FLORA OF COUNTY WATERFORD
Knautia arvensis (L.) Coult.
Native. Road banks, sea-cliffs, dry
rocky areas, banks of disused railways
and dunes. Populations are always
small with the majority of sites found
on road banks. The New Atlas also has
records for S10, S20 and S21 for after
1950.
First record: west of Clonmel, S11 or
S12, 1897, R.L. Praeger.

ASTERACEAE
Carlina vulgaris L.
Carline Thistle
Native. A rare declining plant confined to dunes and unstable cliffs along the coast. All records
are: Co. Waterford (before 1866, I. Carroll); Stradbally Inlet (X39T, 1882, H.C. Hart); dunes of
Tramore Burrow (S60A, 1899, R.L. Praeger – 2003, WFS field meeting); Dungarvan (X29,
1899, R.L. Praeger); Brownstown (X6198, 1960, I.K. Ferguson); cliffs, Kilfarassey (X5298,
1962, I.K. Ferguson); dunes at Bunmahon (X4398, 1967, I.K. Ferguson – 2000, I.P. and P.R.
Green); cliff of small cove, Templebrick, Bunmahon (X4297, 2002, PRG). [The New Atlas has
records for S30, and S40, which are inland squares and for S50, which has a small stretch of
coast, which may be an error for S60. These are likely to be errors made when converting the
old Irish grid to that used today.]
[Arctium minus subsp. minus (Hill) Bernh
Lesser Burdock
Error? There are records for S10, S20, S31, S41, S60 and X29 for after 1950 and for S12, S41
and X19 made by myself in 1997. Without specimens these records should be treated with
caution.]
Arctium minus subsp. nemorosum Lej.
Wood Burdock
Native. Roadsides, waste ground, river
and stream banks, disused quarries and
railways, etc. My opinion is that this is
the only species of Burdock to occur
in the county. It is very different from
what I take to be Lesser Burdock in
southwest England.
First record: Lismore, X09, 1950s, C.
Longfield.

had bronze-coloured leaves, Tramore (S5902, 2006, PRG).
Lactuca serriola L.
Prickly Lettuce
A rare but increasing species in Ireland, still not yet established in the county but likely to be as
it becomes more common. All Co. Waterford records are: six plants on newly-sown road verge

Mycelis muralis (L.) Dumort.
An increasing species, which was
probably a garden escape originally
and now common on walls in the
Lismore and Cappoquin area. Also
found on rock faces, along rides of
conifer plantations and on road banks
and verges. All plants that I have seen
in the county have a purple hint to the
leaves.
