Changes to the Committee
The Management Committee is grateful to
Peter Johnson for his work over the past year
as a Committee Member. Although Peter
stood down from this role in June, I am sure
he will continue to support the Society by
helping our Membership Secretary, his wife –
Sue, with the quarterly despatch of the
Journal. The Committee is delighted to
welcome Linda Seal who was elected as a
Committee Member at the AGM. Many
thanks to all those who stood for re-election.

Neofinetia falcata has moved to become Vanda falcata
Changes to Vandeae
Just when you thought it was safe to stop
renaming your orchids … a recent press release
from the RHS’s Orchid Hybrid Registration
Advisory Group advises further changes to
Vandeae following a meeting in May.
A full account is due to be published in
Volume 6 of Genera Orchidacearum, which is
scheduled for publication in February 2014,
and is the final volume of the series.
The members of the Advisory Group
unanimously recommended adoption of the
proposed changes in the Hybrid Register
immediately, some of which are listed below.
Vanda is to be expanded to include:
Ascocentropsis, Ascocentrum, Christensonia,
Eparmatostigma, Euanthe, Neofinetia and
Trudelia
Papilionanthe is to be accepted as distinct
from Vanda
174 • OSGBJ 2013, 62(3)
Phalaenopsis is to include: Doritis, Kingidium,
Lesliea, Nothodoritis, Ornithochilus and Sedirea
Full details of the proposed changes can be
found on the News page of the OSGB
website, www.osgb.org.uk
PayPal facility on OSGB
website
Members can now make payments to the
Society using the new PayPal facility on
the membership page of our website,
www.osgb.org.uk, including payments for
annual subscription renewals, Colour
Fund donations and purchases of Society
merchandise. However, please contact Val
Micklewright before ordering
merchandise from the website to ensure
the items required are in stock and to
arrange either delivery, collection or the
correct postal charge payable.
The world’s first blue Phalaenopsis were
unveiled at Japan’s 11th Asia Pacific Orchid
Conference in February 2012. Visitors queued
for an hour to view these extraordinary
plants which were dramatically displayed in
spot-lit glass cabinets within a darkened
room, watched over by security guards.

These transgenic flowers were created
through genetic engineering, using a gene
from the Asiatic dayflower, Commelina
communis, which has bright blue flowers.
This was used to replace the colour gene in
plants of Phal. Wedding Promenade. Peloric,
or deformed, blue Phalaenopsis flowers were
also on display, which had been created
before the non-deformed flowers were
finally achieved. Masahiro Mii of Chiba
University delivered a lecture outlining the
different methods trialled over many years
and the final, successful process of genetic
engineering.

Introduction to the President
Introduction to the President
Peter White
I began to check most days until the plant
was in full bloom. The small flowers were
white in colour with a deep red lip and that
was me hooked.
My interest in orchids started over 35 years
ago when a relation of mine was head
gardener at Aynhoe Park, not far from my
home near Banbury.
I searched around to find where to buy more
plants. At that time there were two orchid
nurseries close by – Ratcliffe Orchids, near
Oxford and Wyld Court Orchids, near
Newbury – and this is where I spent my
spare time. My next move was to find a local
orchid society and the nearest one to me
was Solihull & District. I soon became a
member and met many interesting and
experienced orchid growers. After a few
years I became Show Secretary, then
Chairman and now I am that society’s
President.
The tropical house there had a few orchids
and the one that really got me interested
was Cattlianthe (previously Cattleya) Portia.
During one of my visits the plant was being
loaded onto a van heading for the RHS
Chelsea Flower Show; it had over 700
flowers and the rear of the greenhouse had
to be removed as the door was not wide
enough for the plant to get through.
I was given a small Cymbidium to take home
and try. The plant was placed in my 8ft x 6ft
greenhouse along with the tomato plants. I
was checking the greenhouse one winter’s
day and found the Cymbidium was in bud so
Peter White was elected President of the OSGB at the
AGM in June (photo by Sam Hurley)
being nominated to be the next President of
the OSGB. I did not have to give this too
much thought as I knew the people I would
be serving with are hard-working and
dedicated to the Society. I was delighted to
be elected as the Society’s new President at
the AGM in June.
I would like to thank our outgoing President,
Henry Oakeley, in particular for his
contributions to the Journal over the years –
making it one of the best journals around.
Henry has been an ambassador for the OSGB
for many years, both at home and abroad,
and we are all grateful to him for his hard
work.
I was put forward by Solihull & District to
join the BOC judge training scheme in 1987
and qualified after three years. I have judged
at many different congresses around the
world, learning much over the years working
with top orchid growers. In 1996 I started my
business, Orchids by Peter White, growing
and selling orchids, and attending shows at
which I have won many awards including
five RHS Gold medals. I have also achieved
some Awards of Merit and Botanical
Certificates, along with Awards of Garden
Merit for my plants (see page 241).
In 2005 I was invited to join the RHS Orchid
Committee. This was a great honour for me,
being able to work and judge with such
knowledgeable people. Over the years I have
met many people around the world who
share my passion for orchids.

Paphiopedilum hybrid
I was amused to note the flower used to
illustrate the packaging of some vanilla
yoghurt in my local supermarket.
Graham Le Tissier
Dear Editor,
I am writing from Guernsey with reference
to an article by Henry Oakeley in the last
Journal (OSGBJ (2013) 62(2): 92) on
‘curiosities’, a much nicer term than
mutations.
What a shame that Vanilla flowers are not
considered attractive enough in their own
right.
I have a Paphiopedilum with three sepals –
the lateral sepals, which are usually fused to
form a synsepal, have become two.
Personally I find it enhances the appearance
of the flower but then I guess I am biased.
I have had it for four years and it blooms true
every year. It is an unnamed hybrid which I
bought from a local garden centre. I’ve
called it my ‘Guernsey Girl’.
Dendrobium hybrid
Spot the obvious mistake – which orchid flower is this?
(answer at bottom of page)
Sam Hurley (photos by Sam Hurley)
While paying a little more attention than
usual when watering my Dendrobium
kingianum hybrid I notice that it had
produced a ‘curious’ flower – one with two
lips.
I am certainly growing this plant too warm,
with not enough cool winter rest, because it
is covered in a number of keikis, the top one
of which has produced the latest flowers.

Sadly, this time, too good to be true. Many

contacted me about the identity of Judith
Hoggarth’s bargain Phalaenopsis which was
featured in the previous issue (OSGBJ (2013)

primary hybrid Phalaenopsis Wiganiae.
Our new President, Peter White, offers the
following information:
This plant is often seen in garden centres and
supermarkets and is grown by the Dutch
nurseries. It has a commercial name of
‘Philadelphia’ and is an easy plant to grow;
the attractive flowers are slightly scented.
I think the article by Judith Hoggarth shows
what you can find in superstores. From the
‘Judith’s plant is not Phal. schilleriana but a

OSGB Autumn Show and Wraysbury
Orchid Event
Valerie Pugh
The Society’s last show of the year will be on
Saturday 2 November 2013 at Wraysbury
Village Hall, The Green, Middlesex, TW19 5NA,
held in conjunction with the Wraysbury
Orchid Event.
The show will be open to the public from
10:30–16:00. This year judging will
commence later than usual in order to give
members more time to deliver their plants.
Registration of plants will be from 09:00–
11:00, and judging will commence at 11:00.
Entry to the show is free with plenty of free
parking nearby. There will be a wide selection
of hardy and tropical orchids for sale, along
with orchid sundries, from a variety of
traders; a potting demonstration; and talks
about ‘Orchids in the home’ and ‘Orchid
culture’. Refreshments will be available
throughout the day.
Travel directions to the show can be found
on page 22 of the Annual Supplement. For
more information please contact Valerie
Pugh, tel: 01403 251176; e-mail:
[email protected]
Wraysbury can be reached by train on the
line from London Waterloo. Taxis from the
station to the venue need to be pre-booked
as there is no taxi rank at the station (and
paid for by individual members). Members
wishing to arrange for a taxi, or share one,
should contact Kim Solomon (by Wednesday
23rd October please) who will help coordinate bookings, tel: 020 8946 4410,

The OSGB’s Gold medal-winning exhibit at the RHS London Orchid Show
The OSGB exhibit
Our display skills – and specifically André
Roux’s – go from strength to strength. Good
plants and good design are, of course,
necessary for a Gold medal exhibit and the
degree of effort (the RHS calls it ‘endeavour’)
expended is also assessed.
Effort there was! Towering boxes piled on
top of each other, covered with chicken wire,
formed the back-drop; flat sheets of builder’s
grade polystyrene the foreground. A rugged
cliff evolved; vertical sheets of cork bark
draped with long strands of Spanish Moss
(Tillandsia usneoides) formed a two metre
182 • OSGBJ 2013, 62(3)
high, central waterfall falling into a river of
large white pebbles which flowed to an
estuary of grey slate pieces laid over the
polystyrene.
Terry Vasey’s pendant Epidendrum
parkinsonianum with half a dozen
noctilucent flowers, and a delightful
Coelogyne flaccida framed the waterfall, with
historic Cymbidium hybrids and modern
Phalaenopsis on the cliff top. On the
orchidaceous plain, Mike Powell’s Eulophia
guineenensis from Arabia and North Africa
and his European terrestrials, Ophrys,
Dactylorhiza and Orchis, grew together, rising
from the polystyrene (now covered with
moss islands and fields of fine bark
chippings), and were complemented by
Paphiopedilum and clumps of Ludisia discolor
from Asia.
Sheets of moss from the pine forests of
Denmark (via Nine Elms flower market)
covered the chicken wire, with Cattleya,
Phragmipedium, Paphiopedilum, Prosthechea,
Coelogyne and more, growing – as in nature –
epiphytically and lithophytically through the
moss, with not a pot showing. The delicate
foliage of Himalayan Maidenhair ferns
(Adiantum venustum) provided a beautiful
pale green foil to the pink, scarlet, gold, white
and yellows of the orchids.

favourite, Dendrobium Thwaitesiae ‘Veitch’
proving its robustness in cultivation – for this
plant is over 110 years old and gained a
FCC/RHS in 1904. It was surrounded by
Maxillaria from Michael McIllmurray, who
holds the UK National Collection, including
his rambling Maxillariella (previously
Maxillaria) variabilis with over 50 flowers
which commanded a bun-moss island in the
stream.
No plant had a spotted leaf; no flowers
showed travel damage; no scale, aphid, virus
or mealy bug disgraced the stand; not a pot
was to be seen; the boxes, wire, polystyrene,
all vanished under immaculate moss (no
pine needles either) and all that work with
staplers, moss pins, tin-snips, electric
screwdrivers, plant ties, ferrying plants from
around the country, early morning shopping
and leaf cleaning, became ‘orchids in a
naturalistic setting’ and a Gold medal
exhibit.
Plants cascaded down the cliff-face, alongside a
waterfall of Spanish Moss, to spread out across the
orchidaceous plain
The final touch, never to be forgotten, is
superb labelling. Val Micklewright’s crisp
black labels with genus, species and country
of origin (or parentage if a hybrid), provided
that essential, informative, icing on the cake
of a marvellous creation. To the workers who
laboured and advised, to the members who
supplied plants, the OSGB is grateful, but to
our designer and builder, André Roux, whose
‘eye’ made the masterpiece, we join the
judges in simple, unreserved, and enormous
praise (plus a big ‘thank you’). We look
forward to his next display (and all our
members’ contributions to it).
Plant highlights included a 110 year-old Dendrobium
Thwaitesiae (yellow - middle left) and a Maxillariella
variabilis with over 50 flowers on a bun-moss island
André Roux created another enchanting masterpiece for
the OSGB at the RHS London Orchid Show
OSGBJ 2013, 62(3) • 185
The show was well-attended, with an
increased number of visitors to the RHS halls
which are now leased to Westminster
School. It was a pleasure to see so many
educational exhibits in one hall: Helen and
David Millner, Writhlington School Orchid
Project, Laneside Hardy Orchids and
University of Kent.
The Best Orchid Exhibit and Most Creative
Orchid Exhibit awards went to Vacherot &
Lecoufle for their elegant and modern
display of species and hybrids. Writhlington
School Orchid Project won Best Orchid for
Dendrobium thyrsiflorum and Best Specimen
Orchid for Coelogyne cristata forma alba.
Gold medals were won by Burnham
Nurseries, Helen and David Millner, McBean’s
Orchids, Vacherot & Lecoufle, Writhlington
School Orchid Project and the OSGB.
Lea Valley Orchid Society was the only other
society exhibiting amongst the numerous
traders’ displays and created a charming
greenhouse full of orchid treasures.

Dendrobium kingianum – a much
maligned orchid
Dendrobium kingianum – a much maligned orchid
Derek Belcher
Most of us have a sample of this orchid in
our collection, even if it was obtained via a
raffle (often the last of a mixed bunch) or
bought at this year’s auction. But do we
know much about this diverse group?
Dendrobium kingianum is a much maligned
orchid in the UK with small plants available
at giveaway prices or given as ‘freebies’,
whereas in its native country it is much
prized. This species comes from the eastern
coast of Australia, just north of Sydney in
New South Wales, up beyond Brisbane to
Carnarvon Gorge in Queensland.
Its name does not come from a royal
connection, but from a Captain King (1758–
1808), the son of Governor Philip King.
Captain King was instrumental in surveying
Australia’s coast line and in early records this
orchid was known as Captain King’s
Dendrobium and later as the Small Rock
Orchid or the Pink Rock Orchid.
Dendrobium kingianum is highly prized in its native
country of Australia but often disregarded in the UK

188 • OSGBJ 2013, 62(3)
Variations of colour and shape are considerable in Dendrobium kingianum
The growth of this plant varies considerably
as does the colour. The height of the plant
can vary from 7.5cm to 25cm, and its colour
from dark purple to white, and there is some
suggestion that a yellow-flowered variety
exists (at best this is cream). Variations of
colour and lip shape are considerable.
Whatever the shape of the lip, the colours
can vary greatly, from full colour to highlyspotted (which can also apply to the whole
flower), giving an exceptional choice of
effects, including a gorgeous splash effect.
What more could you want in a collection of
orchids, along with flowering from late
winter to early summer?
Dendrobium speciosum hybridises in the wild with Den. kingianum to produce Dendrobium x delicatum

in temperature down to 0°C and up to 40°C.
They require good light year-round although
shading is needed during the summer
months and, as with most orchids, good
ventilation and air movement are important.
Potting should allow for about two years’
growth; choose a pot that will give you about
2.5cm space all-round the existing plant. As
this Dendrobium grows as a lithophyte in
nature it may be advisable to add some small
gravel to the medium, eg 60% bark and 40%
gravel, which may require revision of the
watering regime.
Maximum growth occurs over the summer
and early autumn period, when good light,
ventilation and regular watering should be
provided to promote as much growth as
possible. In the late autumn reduce watering
to allow the canes to mature, and only water
when the potting mixture has dried out. This
will give the plant a rest before it begins to
produce flower spikes. If grown in the right
light conditions spikes will not require
staking and should produce around two to
ten flowers on each spike.
Dendrobium x delicatum (kingianum x speciosum)
This Dendrobium will quickly grow into a
specimen plant expanding each year by 20%
to 30% and when covered in spikes will look
stunning. Yet another bonus is that the
flowers are fragrant but, as with all other
aspects of this plant, it varies depending from
which area it originates.
Because there so many variations it is not
surprising that there are many named plants,
such as ‘Purple Cascades’, ‘Pink Icicle’, ‘Peaches
and Cream’ or ‘Shady Lady’. But even without
varietal names they must be worth growing,
so why not set about growing some varieties
into specimen plants?
For a plant that was first named by John Carne
Bidwill in 1844 it is a shame we do not see
more specimen plants on our show tables.

Around 300,000 orchid enthusiasts visited
the Japan Grand Prix International Orchid
Festival held over nine days at the Tokyo
Dome baseball stadium in February.
The Grand Champion Plant this year was a
single-flowered Phragmipedium kovachii
‘Second Smile’ which was a marked contrast
to the multi-flowered plants that have won
in previous years.
However, second prize went to such a plant,
a specimen of Cattleya trianae ‘Okada’ which
was nearly two metres in diameter and
displayed over 200 flowers. This also won the
RHS Trophy for Best Specimen Plant.
Phragmipedium kovachii ‘Second Smile’ won Grand
Champion Plant at the Tokyo Done show in February
Both plants were grown by Dr Masahiro
Saito who grows a limited collection, albeit
full of specimen plants, in a greenhouse
described by Henry Oakeley as ‘not huge’.
Henry wrote about his visit to Dr Saito in
OSGBJ (2012) 61(1): 7.
The thousands of visitors to the vast show were greeted by a giant clock decorated with colourful orchid hybrids
While many of the orchid displays were large
and bold, suitable for the stadium venue,
there were also enchanting small displays of
‘miniature gardens’.

Photographic and Art
Competition 2013
Sam Hurley
Members attending the AGM in June had the
added bonus of viewing and voting for
entries in the Photographic and Art
Competition. The rising popularity of the
Christmas lunch party in December meant
that this competition was becoming
marginalised so it was transferred to the
June meeting to allow more time and space
to be devoted to it. The move seems to have
proved a success all round; entries to the
competition were up 50% on last year and
the AGM was better attended.
Members successfully navigated the latest
changes to the competition rules and
classes, the main change being the increase
in minimum photograph size from 7 x 5
inches (17.8 x 12.7cm) to 8 x 6 inches (20.3 x
15.2cm). This made the images easier to view,
particularly when held up to the audience
for final voting to decide the trophy winner.
The competition received 76 entries from 15
members, two of whom took advantage of
being able to enter by post. After voting,
Henry Oakeley kindly talked about the
various class winners, discussing the relative
merits of each photograph.
The winner of this year’s Photographic
Trophy (and of Class 1) was Nigel Johnson,
whose image featured a Male Digger Wasp
(Argogorytes mystaceus) resting on the
flower of a Fly Orchid (Ophrys insectifera). It
perfectly depicts the similarity between
flower and insect and raises a smile as one
realises just what one is looking at. Being

able to photograph both flower and insect is
always a bonus and this entry proved the
runaway winner for the trophy. Nigel took
the image with an Olympus OM2SP camera
with a Zuiko 50mm macro lens using Fuji
Velvia 100 film. He entered a number of
superb images, mainly in the habitat classes.
Classes 1 and 3 are for photographs of orchid
plants, flowers or parts thereof. They should
act as portraits and be accurate and
appealing representations of the orchid
concerned. Robert Simmons’s winning entry
in Class 3 of Paphiopedilum haynaldianum
was just that. Robert’s images are always
immaculate - beautifully lit and showing
incredible detail. This clear image is in sharp
focus, showing the delicate hairs on the
petals and stem. Robert took his image of
Dave Thurtle’s plant using a ring flash with
his Olympus E-5 camera fitted with an
Olympus 50mm macro lens, using manual
exposure at 1/250 sec, f8, ISO100.

The habitat classes (Classes 2 and 4) are
designed to give clues as to how plants grow
in nature – their habitat and its atmosphere.
I was delighted (not to mention astonished)
to find that I was the winner of both classes
and can only advise members to head for
Ecuador, for that is where I took both
photographs. My image of Fernandezia
subbiflora won Class 2 and shows these
miniature plants with their gem-like flowers
growing on a tree branch covered with moss
and lichen. The light is quite dull because,
while we were photographing, cloud rolled
in across the field where these plants were
growing at altitude.

twigs on which this epiphyte grows
OSGBJ 2013, 62(3) • 197
My image of Telipogon tesselatus, winner of
Class 4, tells a different story. The
surrounding thin branches show this plant
growing as a twig epiphyte and the bright
light shows that it enjoys full sun although it
too grows at altitude and can be subjected
to cool, damp cloud cover at times. To get
good photographs I need time to fiddle with
the multitudinous camera settings but when
one is in a tour party of 14, all being very
British and politely queuing to photograph
the latest discovery, time is in short supply.
So I was not surprised to find that both
images were taken using the Auto setting on
my Nikon D3000 camera which is usually a
quick and reliable default position and
produces surprisingly good results.
Class 5 for photographs of an orchid display
was won by Stuart Meeson’s dramatic image
of the Vanda walk, staged during Kew’s
Tropical Extravaganza, which draws one
down the path into the photograph. The
purple and orange arches of vandas contrast
boldly with each other and are perfectly
highlighted by the dark green foliage and

Chelsea’s centenary 1913-2013
Sam Hurley
Val Micklewright changed my life (for a few
months at least) with eight little words:
‘Come on, Sam, we could do it together’. She
was proposing that we design, mastermind
and build the OSGB’s exhibit at Chelsea’s
centenary show this year. We did it
(together) and it was wonderful; the Gold
medal was a great bonus and a credit to the
phenomenal team effort produced, yet
again, by members of this Society.
Val and I decided to start small for our first
Chelsea display and try to create something
slightly different to celebrate the show’s
centenary. We settled upon an educational
exhibit which would include information
panels along the front of the stand offering
visitors some introductory facts about
orchids. Education is, after all, one of the
remits of the Society. Our background site
was smaller than previous island sites and in

an excellent position by the Bull Ring
entrance to the Grand Pavilion.
The display was designed to highlight
changes in orchid growing over the years,
which have often reflected changes in
society and fashion. In 1913 suffragettes
attacked the orchid houses at RBG Kew, in
protest at the male-dominated world of
horticulture. In 2013, and for the first time,
two female members of the OSGB designed
its display for the flagship show of the RHS,
whose president is a woman. A flamboyant
corsage used to be the de rigeur orchid
accessory but today’s must-have orchid
accessory is more likely to be a modern
hybrid for the windowsill.

genera which have been popular over the
past century. Members’ plants, many of them

We were delighted to receive sponsorship
from the Sultanate of Oman Ministry of
Tourism. Oman’s diverse landscape includes
over 3,000 kilometres of sandy Indian Ocean
beaches; magnificent desert expanses;
majestic fjords in the north; and lush green
valleys in the south. A number of orchids are
native to Oman, including Epipactis, Eulophia,
Habenaria and Nervilia. Eulophia guineensis
grows in the tropical highlands in southern
Oman and, thanks to Mike Powell and Penny
Hayes, we were able to feature this species
on the display. A new Botanic Garden is
being created near Muscat, Oman’s capital,
with the aim of displaying the entire flora of
the Sultanate, including its native orchids.
Val and I are incredibly grateful for all the
help and support we received for this show,
and offer our sincere thanks to everyone
involved. Simon Waddilove kindly took a
week’s holiday to help us and was a joy to
work with; Jeanette Beaney dealt with the
RHS online administration; and Mary-Jane
Hawkins acted as sponsorship liaison.

McBean’s Orchids are one of only three
nurseries to have exhibited at the original

since. In celebration of this they recreated
their 1913 exhibit using an old sepia print for
reference and produced a flamboyant
display, in the high Edwardian tradition. The

plants than are used for modern displays, to
create the massed layers of colourful blooms

Table Shows
April 2013
André Roux
Filled with uncertainty by the seeming
paucity of plants in bloom for our display at
London Orchid Show, it was with no small
measure of trepidation that I peered through
the crowd towards the display table … and
exhaled a sigh of sweet relief. And, amongst
the more ostentatious colours and attentionseeking flowers, there was, as is usually the
case, an unusual orchid.
That said, you might counter with the
opinion that Sally Mill’s Coelia triptera is to
orchids what Marmite is to condiments. The
fat, clustered pseudobulbs, which are
sometimes intertwined with the straggly
roots, are topped with three or more tall
plicate leaves that narrow tightly at their
base to form a long stem. Curiously short
inflorescences arise in spring with the onset
of new growth, bearing sweetly fragrant
white flowers that do not fully open and last
less than a fortnight. The long floral bracts
are particularly apparent, radiating outwards
like spines. Native to Mexico, Guatemala,
Cuba and Jamaica, this species grows as an
epiphyte in low elevation forests and
benefits from a fairly dry winter rest but
copious watering during the rapid growth
phase. First described as an Epidendrum in
1793 and later transferred to Coelia in 1840,
Coelia triptera used to be the only recognised
species in the genus but today is one of five.
In contrast, although the magnificent
Epidendrum parkinsonianum is considered by
some experts to be a member of the genus
Coilostylis, this is yet to gain general
acceptance. The large blooms are startlingly
beautiful in their simplicity and it is hardly
surprising that this species is highly prized. It
typically grows as an epiphyte, hanging from
branches at the top of the tree canopy, and
occasionally as a lithophyte on cliff faces.
Epidendrum parkinsonianum is widespread
from the southern states of Mexico through
Central America to Panama with the
exception of Belize, at altitudes from 1,000–
2,300m. Whilst this variation in habitat
introduces a degree of tolerance to a range
of conditions in cultivation, there are some
important constants. The long (almost

lugubrious) fleshy, greyish-green leaves
indicate a need for light that is bright but
indirect; excellent drainage and air
movement will help avoid any chance of rot
to which this species is prone if kept too
damp, particularly in winter; and, for a plant
intolerant of disturbance, a robust potting
medium that will endure in good condition.
Coelogynes are also sensitive to damage
when repotting, and careful handling should
prevent them throwing a sulk. Described in
1905 and named in honour of Sir James
Lawrence, a former President of the RHS,
Coelogyne lawrenceana, exhibited by Norma
Burgess, has long been popular for its sizeable
flowers, the lips of which are crowned with
prominent, intricate, ribbon-like, lamellae.
Although the inflorescences are slow to
mature, the successive blooming habit and
waxy substance of the flowers make for a
long-lasting display. It is a Vietnamese species,
found on the western slopes of forested
mountains in the south of the country, and
enjoys cool but frost-free temperatures with
ample humidity and moisture.
Paphiopedilum haynaldianum is an endemic
species too, further east though on the
Philippine islands of Luzon and Negros. Closely
related to Paphiopedilum lowii, from which it
may be distinguished by the large blotches on
both the petals and narrow dorsal sepal
(among other features), it is undoubtedly one
of the loveliest of the ‘coloured’ multi-florals.
Growing mostly terrestrially or lithophytically
in its natural habitat, this species experiences
the monsoon throughout the summer, with
the warmest temperatures in spring. Humidity
and rainfall remain significant during winter
but night-time temperatures can drop very
low. Discovered in 1870, Paphiopedilum
haynaldianum was named in honour of
Cardinal Lajos Haynald, Archbishop of KalocsaBács in Hungary who, as a young priest, was an
ardent student of botany and collected many
plants and books. (Ed: please see page 196 for
Robert Simmons’s photograph of David
Thurtle’s Paphiopedilum haynaldianum.)

More often than not, Napier Hall is buzzing
when I arrive, but I had the distinct
impression at the May meeting that it was
the vivid colours emanating from the display
table that were reverberating equally
excitedly, shimmering in the diffused
afternoon sunlight pouring through the
windows. Spring, it seemed, had finally
unfurled itself and of this there was no
clearer affirmation than the presence of
those enchanting dendrobiums from Section
Densiflora.
Dendrobium chrysotoxum bears glowing
golden flowers that resemble the sun itself.
Unhappily they are, in common with the
species in this group, all too short-lived – it is
understood that the flowers are self-sterile
and fall about ten days after self-pollination
has occurred. Results of one study
demonstrated, however, that crosspollination within Dendrobium chrysotoxum
was highly successful, almost all flowers
producing viable capsules leading to
germination of over 75% of the seed. This
delightful species demands warm
temperatures, high humidity and frequent
watering when in growth, mimicking the
summer monsoon of its native habitat,
where, although days are seldom clear,
plants will bear exposure to bright light in
the early morning. Generous fertilising will
result in vigorous growth but it is vital to
ensure that salts do not accumulate in the
mix, as this leads to poor roots, shrivelling of
pseudobulbs, and even to the demise of the
plant. Winter daytime temperatures are
barely cooler than during summer but drop
markedly at night to an average of 10°C. Early
winter sees high humidity from fog and mist
so plants should not remain dry for long; in
late winter the atmosphere is very dry and
they will benefit from a cool, almost
completely dry rest and bright light to
encourage blooming.
Dendrobium lindleyi (previously Dendrobium
aggregatum) shares its distribution across
north-east India, Myanmar, south-west
China, Thailand and Laos with Dendrobium
chrysotoxum, but it is also located in Bhutan
and Vietnam. The small plants can be found
growing on the trunks and branches of
deciduous trees in montane forest. Cultural
requirements are similar to those described
above, although Dendrobium lindleyi enjoys
brighter light, particularly in winter, and
strong air movement. A cool, very dry rest of
four to five months during this latter season
maintains the health of this species and its
blooming; while the pseudobulbs will shrivel
naturally during this period, early morning
misting is recommended and plants should
not remain completely dry for long periods.
Under cool and dry conditions, the honeyscented flowers will last for up to three
weeks, dropping seven days after selfpollination.

Hummingbirds surely rank among the most
glamorous of orchid pollinators and it is the
fiery blooms of Cattleya (previously
Sophronitis) cernua that attract these
fascinating birds. Described in 1828 and
native to south-eastern Brazil, slipping into
Paraguay and Argentina, this charming
miniature species tolerates the warmest
temperatures when compared to its sibling
species. Plants naturally grow predominantly
on rocks, nestled in a layer of Sphagnum
moss, and are exposed to strong light and
buoyant, refreshing breezes. They produce
two growths a year although it is only the
pseudobulbs which mature in winter that
flower. All factors considered, constant high
humidity (averaging 80%), plentiful moisture
and cool temperatures are critical to the
health and blooming of Cattleya cernua.
Cattleyas have long been deemed the queen
of orchids by virtue of their lavishly
decorative blooms, and the attraction never
seems to wane. No revelation, then, that
Cattleya Tokyo Magic (Irene Finney (1964) x
briegeri) proved a much-admired entry on
the display table. Hybridisers have excelled
at creating increasingly intense hues and
colour combinations; larger and shapelier
flowers; and plants which have diminished in
size to the extent that they can be cultivated
on windowsills. Good light levels, humidity
and warm to intermediate temperatures are
the core requirements in Cattleya culture;
watering is, perhaps, the trickiest element
and it is sensible to allow the potting
medium to become almost dry between
applications.
Sarcochilus, on the other hand, appreciate
cooler conditions with increased shade and
even moisture at the roots. Hybrids, beyond
the inevitable Sarcochilus Fitzhart, are less
well known – a great loss when the true
extent of their number is more closely
investigated. What was a writer’s-cramp of a
label, Sarcochilus [Fitzhart ‘Tambet’ x (Hot Ice
x fitzgeraldii ‘Red Rock’)] has been registered,
simply, as Sarcochilus Marlene. With its
fetching rose-purple flowers pleasingly
arranged on the inflorescence, this hybrid
offers a revitalising aspect of Sarcochilus
breeding that is steadily producing ever
more colourful and intricately patterned
flowers.

The judging of orchids is an aspect that may
be viewed as adding value and expanding
knowledge, a vanity project, perhaps – after
all, loveliness is purely subjective – or
altogether a rather mysterious other-world.
While it undoubtedly involves years of
training and practice to qualify in this field
(indeed, it is a lifelong dedication given the
immeasurable diversity of our fêted plants),
some of the basic principles are within
anyone’s reach, as illustrated by a few of the
specimens that caught my eye in June.
Masdevallia coccinea is a fine, cool-growing,
high altitude species from Colombia and
Peru renowned for its purity of colour,
flowers held grandly above the foliage,
flaming. The clone on display was
exceptional, quite likely a tetraploid, with
exceedingly tall inflorescences. Apart from
the trademark radiant colour, the flower was
perfectly symmetrical and of full form, both
lateral sepals meeting along their entire
inner margin and excluding any ‘windows’ of
light. Alas, only one flower was fully open to
champion its genetic finery – to be worthy of
a ranking, two-thirds of flowers, where this
can reasonably be expected, should be open
on a plant submitted for judging.
Sarcochilus Marlene is one of an increasing range of
hybrids in this genus
And that was a winning feature in favour of
Masdevallia welischii, a charming Peruvian
species described some 130 years after its
relative above. This species is reminiscent of
Masdevallia veitchiana, having squatter but
similarly scarlet-orange blooms but with the
dorsal sepal covered with minute, iridescent,
purple papillae. Crowning healthy foliage, all
flowers were in peak condition and well
positioned around the perimeter of the plant
to create a pleasing display.

symmetrical blooms

Today, the source of species material is largely
derived from the selective breeding of quality
clones and it is fair to attribute at least a
portion of that approach to benchmarks set
by the judging system. A case in point was a
striking Cattleya (previously Laelia) purpurata
(‘Rio do Sul’ x ‘Schusteriana’). Clarity and
defined contrast are key tenets when
evaluating colour, beautifully pictured in this
highly variable Brazilian species which is
grown by more devotees than one might
imagine, many of whom grow no other
orchids. Nevertheless, colour quality is not
the exclusive preserve of the genes – texture
(surface appearance) and substance
(thickness) of the flower parts can either
enhance or undermine it. In this clone, the
sparkling texture of the fleshy sepals and
petals, married with the velvet of the lip, was
unquestionably flattering.
Sally Mill’s Cattleya (previously Laelia) purpurata (line-bred from the cultivars ‘Rio do Sul’ x ‘Schusteriana’) exemplifies
high quality flower texture and substance
222 • OSGBJ 2013, 62(3)
Patterns or markings are desirable features in
many orchid flowers and their clarity and
harmony is an important consideration. Poor
definition, bleeding or fading of one colour
into another, is a less pleasing trait; Tolumnia
Volcano (a hybrid I could not validate on the
International Orchid Register, oddly) boldly
portrayed the opposite. Furthermore, the
flowers were neatly arranged towards the
top of the arching inflorescence, a
characteristic of this genus, without undue or
irregular crowding. Also referred to as
equitant oncidiums, in reference to their
distinctive fan of three-sided leaves, Tolumnia
species hail from the Caribbean and are
intolerant of poor-quality water or excessive
fertiliser, both of which damage the roots.
Tolumnia Volcano is belongs to the equitant oncidiums;
‘equitant’ referring to its fan of leaves
There are fortuitous occasions, of course,
when the fundamental judging criteria are all
represented as an agreeable whole.
Cypripedium Cleo Pinkepank (kentuckiense x
macranthos) was one such, a healthy plant
with immaculate foliage and robust stems,
barely noticeably tied to discreet supporting
stakes. Each growth appeared to be
performing to its potential, equal in height to
its neighbour and topped with a well-formed
and attractively coloured flower in pristine
condition. Encouragingly, this temperate
region hybrid slipper orchid represents a
quietly growing trend that looks set to bring
immense pleasure in the years ahead. It goes
by the trade name Cypripedium Kentucky Pink
though, according to the International Orchid
Register, it has been given three legitimate
grex epithets depending on which variety of
Cypripedium macranthos was used, but
Cypripedium Cleo Pinkepank is the earliest
registration and should be regarded as the
correct name.

Trey Sanders – Dendrochilums: species and
general culture
Mary-Jane Hawkins
At our April meeting Trey Sanders gave the
Society a lecture, with a PowerPoint
presentation to show us what Dendrochilum
look like and how to grow them.
Trey has been growing the genus
Dendrochilum for over 26 years; he started in
his backyard in Australia when he was 12 and
continued when he moved to England in
2003. When Trey lived in London, he was a
Dendrochilum originate from the Malesian
region, which includes; the Malay Peninsula,
Indonesia, Borneo, Papua New Guinea,
Philippines and Sumatra. The greatest
concentration of Dendrochilum is in the
Philippines where 112 species are found
which is 37% of all Dendrochilum species. It is
believed that Dendrochilum evolved from the
Pholidota section Acanthoglossum, which is
primarily found in Borneo, and they are part
of the Coelogyninae family which (amongst
others) includes Pleione, Pholidota,
Chelonistele, and Coelogyne.
The grass-like Dendrochilum tenellum is one of the more widely available species
Dendrochilum were first discovered by Carl
Blume while travelling around South East
Asia in the 1820s. He wrote up his orchid
discoveries in 1825, creating the genus
Dendrochilum and describing six species,
splitting them into two sections. More
species continued to be discovered, and
J J Smith wrote the first monograph on
Dendrochilum in 1904, describing 43 species.

be worth having a look at YouTube to see if
there is any footage from amateur trekkers
who have explored some of the mountains.
Air movement is essential when growing
Dendrochilum, as in the wild they grow in
exposed conditions on the tops of
mountains, on rocky ridges and on cliff faces.
Humidity is also important, as these orchids
are mostly mossy cloud forest plants and
even those which live at low elevations
experience high humidity. The majority live
at high altitudes and are cool-growing;
however, there are some that grow at lower
altitudes which are warm-growing.
Trey has found that fine potting media, such
as coconut husk and live Sphagnum moss,
get good results. Dendrochilums do not like
to be repotted, and they can sulk afterwards,
Dendrochilum wenzelii is a highly variable species with
yellow, orange or red flowers
Dendrochilum cymbiforme grows in cloud forests on the
island of Luzon in the Philippines (photo by Henrik
Pedersen)
with some species losing their leaves or even
dying, whilst others may not flower for a
couple of years. Dendrochilum enjoy plenty of
water and it is important not to let them get
dry. The exception to this is Ddc.
convallariiforme and a few others which
prefer to be kept drier. Apart from these, Trey
grows his Dendrochilum in pots sitting in
water. The water quality needs to be good as
they do not like hard water. Some of Trey’s
plants do better if they are mounted, or
attached to a wet mossy pole; he has done
this quite successfully with some of his
species and it makes an attractive feature.
Trey has found that feeding Dendrochilum
results in better flowering. However, it is
important to give Dendrochilum only welldiluted fertilizer and not to over-feed them
or the tips of their leaves go brown; flushing
Species have continued to be discovered and
today almost 300 have been described. The
more common species include: Ddc. tenellum,
Ddc. pangasinanense, Ddc. wenzelii (a highly
variable species with yellow, orange or red
flowers), the widespread Ddc. gracile, and
Ddc. longifolium.
During his talk, Trey also looked at how to
grow Dendrochilum. He made a point of
emphasising that what works for him may
not necessarily work for others, and growers
need to try out different things. It is most
important to research where orchids come
from, and their growing conditions. Trey
suggested that it might be a good idea to
see what cloud forests (where Dendrochilum
tend to live) look like. He added that it would

the potting media with rainwater should
overcome this problem. Other problems
which can be encountered when growing
Dendrochilum include rotting new growth,
especially if growing indoors, and bud blast
which can occur if the plant is kept too dry or
in a room which is too warm. As with many
orchids, red spider mite is the commonest
pest.
There are many beautiful Dendrochilum, but
two which stayed in the mind after the talk
were Ddc. Tortile, which is an amazing
species that carries its flowers upside down,
and Ddc. septemnervium which smells of
crushed millipedes!

Ian Parsons – The genus Phalaenopsis
Mary-Jane Hawkins
In May, Ian Parsons, the Chairman of the
British Orchid Council, visited Napier Hall to
talk about the genus Phalaenopsis. For many
years, the only book available was The genus
228 • OSGBJ 2013, 62(3)
Phalaenopsis (1980) by Herman Sweet, which
successfully organised random papers into a
comprehensive publication, but this was
superseded by Eric A Christenson’s
Phalaenopsis: a monograph (2001). Ian’s talk
was based on the original classification
carried out by Herman Sweet, although he
also showed two charts which set out the
accepted classification up to 2012, along with
numerous images of species, and their
varieties, in the different Sections. (Ed: for the
sake of clarity, Christenson’s classification of
Phalaenopsis has been used in this report.)
Ian’s first experiences of Phalaenopsis
occurred over 40 years ago, when he grew
hybrids in his university office. An elderly lady
(a professor of bacteriology) invited him to
look at her species Phalaenopsis which she
grew in a warm and bright conservatory
(with humidity at 70%) in an old Victorian
house, heated by a coal-fired central heating
system which she had to stoke every morning
and evening. Ian left with a list of 20
Phalaenopsis species which she was growing
and from that moment on he was hooked.
Native to South East Asia, Phalaenopsis
species are widespread, ranging from
eastern India to Papua New Guinea. Some
are found on both sides of the Wallace line,
generally grouped around geographical
areas including the Indian sub-continent and
Myanmar, with other groups in Thailand and
Malaysia and some further out in the
Philippines and Indonesia. (Ed: the Wallace
line runs through Indonesia, between Borneo
and Celebes, separating the plants and
animals of Asian origin to the east and of
Australian origin to the west.)
The genus is divided into five subgenera and
over 50 species. Like many other genera
Phalaenopsis has been reclassified for many
reasons, including DNA testing. The
subgenera are: Phalaenopsis, Aphyllae,
Proboscidioides, Parishianae and Polychilos.
Paraphalaenopsis, which used to be in
Phalaenopsis, can be separated on the basis
of DNA studies.
shedding their leaves in dry conditions,
growing new ones and flowering when it
rains again, which is very different from the
hybrid Phalaenopsis we know, which die if
kept too dry. This section is comprised of
Phal. chibae, a variety with small flowers and
upright stems native to Vietnam, discovered
and named in 1996; Phal. deliciosa; and Phal.
mysorensis.
Subgenus Phalaenopsis
Subgenus Phalaenopsis contains some of the
species with which we are most familiar and
is split into four Sections: Phalaenopsis,
Deliciosae (previously the separate genus
Kingidium), Stauroglottis and Esmeralda
(previously the separate genus Doritis).
Section Stauroglottis
Section Stauroglottis is made up of Phal.
celebensis, white with brown centrally; Phal.
equestris which produces long flowering
stems with lots of small flowers; and Phal.
lindenii which has a spectacular little flower
with stripes on the lip.
Section Phalaenopsis
Section Phalaenopsis is comprised of six
species: Phal. amabilis, which has large white
flowers measuring 5–8cm across; Phal.
aphrodite also a large white; Phal.
philippinensis which comes from the
Philippines and has spotty leaves and
spotting at the base of petals, with the
colouring of the flowers ranging from white
to pink; Phal. sanderiana which produces eyecatching flowers with a flesh-pink lip and
markings; Phal. schilleriana which has
marbling on the leaves which is often the
source of the mottling seen in hybrids and
produces a profusion of flowers which vary in
colouring from plant to plant from white to a
deep rose pink; and Phal. stuartiana which
has a differently shaped, larger lip and, like
Phal. schilleriana, is very variable in the wild.
Section Deliciosae
Most Section Deliciosae are deciduous,
Phalaenopsis chibae, discovered as recently as 1996, has
small flowers and upright stems
OSGBJ 2013, 62(3) • 229
Section Esmeralda
Unlike the epiphytic Phalaenopsis, the
species Phal. pulcherrima and Phal.
buyssoniana in Section Esmeralda are
terrestrial and can be lithophytic, growing in
leaf litter and humus. They have upright,
seasonal growth; around the base of the
shoot they grow a collar from which new
roots are produced, an adaptation to the
rising levels of leaf litter experienced in
nature. They produce a vertical flower spike
with flowers at the top and have been used
in hybridisation to improve colouration as
they are a brilliant purple.
Subgenus Aphyllae
The subgenus Aphyllae has been reworked
and includes Phal. wilsonii, which like all the
Aphyllae species, is deciduous with the flower
spikes coming out of a mass of roots. During
the dry season it sheds its leaves to survive,
creating a cork layer across the base of the
leaf, and new leaves grow when the plant has
water. This subgenus also includes Phal.
stobartiana (syn. Phal. hainanensis), Phal.
honghenensis, Phal. finleyi (syn. Phal. minor)
and Phal. taenialis, a species which has next
to no leaves and comes from the eastern side
of India, Sri Lanka and up into Myanmar.
Subgenus Proboscidioides
Subgenus Proboscidioides contains just one
species, Phal. lowii. This species had been
thought lost in the wild until it was
rediscovered in 1996. Although not very
floriferous, it has dainty fragrant flowers
which have a long beak-like rostellum (part
of the column).
Phalaenopsis stobartiana, like all species in the subgenus Aphyllae, is deciduous, shedding its leaves in the dry season
230 • OSGBJ 2013, 62(3)
Subgenus Parishianae
Subgenus Parishianae is characterised by the
keels and markings on the lip and the
general structure of the base of the flower. It
includes Phal. parishii, Phal. lobbii, Phal.
gibbosa and Phal. appendiculata.
Subgenus Polychilos
Subgenus Polychilos is a large subgenus
containing four Sections: Polychilos, Fuscatae,
Amboinenses and Zebrinae.
Section Polychilos
Section Polychilos contains Phal. cornu-cervi,
widespread from the Philippines through
Indonesia to Myanmar; and Phal. mannii,
which has two long wings on the flower’s lip
which fold up (a characteristic of the group).
Phalaenopsis borneënsis, Phal. lamelligera,
Phal. pantherina and Phal. thalebanii are all
now considered synonyms of Phal. cornu-cervi
according to the Kew Monocot Checklist.
Section Fuscatae
Species in Section Fuscatae include Phal.
fuscata, Phal. viridis, Phal. cochlearis and Phal.
kunstleri, with yellow flowers variously
marked with brown. Phalaenopsis cochlearis
differs from the others in having a concave
lip, the edges being turned up all the way
round and resembling a cockleshell, with
longitudinal stripes.
Section Amboinenses
Section Amboinenses contains some of the
largest Phalaenopsis. Phalaenopsis
amboinensis is a large plant with flowers
measuring 7.5–10cm. Ian showed us a
Phalaenopsis cornu-cervi is widespread from the Philippines through Indonesia to Myanmar

photograph of one growing in the wild,
which had thick, leathery leaves 30–45cm
long, with the roots extending for metres up
and down the tree. Markings are generally
arranged around the flower in concentric
patterns. Other species in this section are:
Phal. floresensis; Phal. gigantea (which is well
worth growing as it has big, bold flowers, big
leaves, but is a huge plant to manage); Phal.
javanica; Phal. micholitzii, which has
beautiful dainty flowers that are translucent
when they have rain on them; Phal.
robinsonii; and Phal. venosa.
Also in this section are Phal. violacea (often
the source of the ‘blue’ in blue hybrids) and
Phal. bellina, which were originally thought
to be the same species. Phalaenopsis violacea
Phalaenopsis gigantea has big, bold flowers but can be a
huge plant to manage
232 • OSGBJ 2013, 62(3)
grows in the Malaysian Peninsular whilst
Phal. bellina grows in Borneo. They have
different scents and are probably pollinated
by different insects. DNA analysis has shown
that only some Phal. violacea/Phal. bellina
populations are separate species. (Ed: only
the populations of Phal. violacea on Mentawi
island are shown by DNA analysis to be
separate from Phal. bellina, giving rise to the
concept of only Phal. violacea var. mentawi
being separate from Phal. bellina).
For completeness, this section now includes
Phal. pulchra, Phal. fimbriata, Phal. fasciata,
Phal. doweryënsis, Phal. luteola, Phal. modesta,
Phal. maculata, Phal. mariae, Phal.
lueddemanniana, Phal. reichenbachiana, Phal.
pallens, Phal. bastianii and Phal. hieroglyphica.
Phalaenopsis bellina is native to Borneo and often
confused with Phalaenopsis violacea (native to the
Malaysian Peninsular)
Section Zebrinae
The final Section, Zebrinae, contains Phal.
corningiana and Phal. inscriptiosinensis
whose name means ‘Chinese writing’ due to
the markings on the petals which look very
similar to those of Phal. hieroglyphica (now
in Section Amboinenses, where the markings
on the petals resemble hieroglyphs).
Phalaenopsis inscriptiosinensis has a
particularly pronounced restriction of the lip
as do Phal. tetraspis and Phal. speciosa, also
members of the Section, which have
asymmetric, blotchy flower markings which
vary from flower to flower so each is unique.
Paraphalaenopsis
There is a final genus, Paraphalaenopsis, over
which debate raged as to whether it should

be included within the genus Phalaenopsis
until it was separated in 1975/6.
Paraphalaenopsis is made up of four species
(Para. denevei, Para. labukensis, Para. laycockii
and Para. serpentilingua) which are only
found in Borneo.
They are different from Phalaenopsis in two
respects: they exhibit a marked difference in
their leaves from Phalaenopsis, the leaves
bring long (up to two metres) and cylindrical
(terete), and they are incompatible
genetically. It was believed that they had a
different chromosome count which stopped
cross pollination to Phalaenopsis, but Ian
advised that recent work by the University of
Singapore showed the chromosome count to
be the same as all but one Phalaenopsis (Ed:
Paraphalaenopsis labukensis is native to north Borneo
234 • OSGBJ 2013, 62(3)
this is contrary to the findings reported in
Genera Orchidacearum Volume 1). Ian told us
the National Taiwan University reported that
crosses may be difficult due to the genome
properties of the genera which arise from
their evolving in differing environments to
adapt to altitude and humidity (Ed:
differences in the genes is, of course, why
most genera do not hybridise). Ian’s opinion
was that there is good evidence to dispute
the claim that Paraphalaenopsis are not part
of the Phalaenopsis genus.

A Christenson is available from the OSGB
library. A pictorial guide to identification of
