Introduction
Previous versions of this publication were based on the Ontario Plant List (OPL),
published by the Ontario Ministry of Natural Resources, 1998. There have been some
notable changes in plant systematics and nomenclature over the past 15 years
necessitating the need to update this species list. As a result of research associated with
the publication of the Flora of North America (26 volumes in total) many taxonomic and
nomenclatural updates have appeared in the literature.
Concurrently, additional alien and native species have been observed and are now
recorded as part of the flora of Ontario. With the release of this 3rd edition of the Southern
Ontario Vascular Plant List there is a more harmonious linkage with the plant names
listed in web based databases such as NatureServe, PLANTS, VASCAN, FOIBIS and
ITIS.
The main function of this document is to provide a list of standardized species codes
which can be used to quickly record plant species. Although this list has been compiled
for use with the provincial Vegetation Sampling Protocol (VSP) and Ecological Land
Classification (ELC) programs, it can also be used by other researchers who are
collecting field data in southern Ontario. These seven digit species codes are used by
ecologists and biologists to speed up the time required to document plant species
observed in the field.
With over 3,400 plant species [including subspecies, varieties and hybrid forms] to
choose from (Natural Heritage Information Centre web site, 2011) it can sometimes be a
bit problematic when identifying plants in the field. In an effort to simplify this process,
plant species normally not observed in southern Ontario have been removed. Excluded
species are those found in northern Ontario (Boreal Forest Region, north to Hudson Bay)
and western species which are normally restricted to the Kenora, Rainy River and
Thunder Bay districts. This brings the number of species down to roughly 2,900 species.
This is still a sizable number of species to work with, but it does reduce the number of
species to below 3,000. As a consequence of using this list, the accuracy of our field data
has improved, eliminating records for more northern species which are not normally
found in southern Ontario.
ii
Geographical Coverage
This species checklist has been compiled in order to assist field biologists who are
sampling vegetated communities in southern Ontario. The intended range of coverage is
ecoregions (Site Regions) 5E, 6E and 7E.
iii
Total Number of Species
John Morton and Joan Venn, University of Waterloo, published A Checklist of the Flora
of Ontario - Vascular Plants in 1990. The total number of species in the province at that
time was 2,888 species (including subspecies and varieties). In 1998, the Ontario Plant
List was published by the Ontario Forest Research Institute, a branch of the Ontario
Ministry of Natural Resources, which provided a listing of 3,340 vascular plants (tree,
shrub, herbaceous and fern species). A more current number of over 3,400 plant species
is listed on the Natural Heritage Information Centre (NHIC) website.
Our provincial flora is dynamic in nature, changing from year to year. Each year seeds
from non-native species are introduced into new environments within the jurisdictional
boundary of Ontario. Sometimes these are accidental introductions, where seeds are
attached to incoming railway cars, boats, or automobiles. Other introductions are a
consequence of planting horticultural species in urban landscapes, and the subsequent
dispersal of seeds into surrounding areas.
There are also a few instances when plants were deliberately introduced into our flora.
For example, White Mulberry (Morus alba) was planted in eastern north America to
provide a food source for the Mulberry Silkworm (Bombyx mori). It was hopped that a
North American silk industry could be developed replacing the importation of silk from
China and Japan. However, the invention of modern day synthetic materials put an end to
this endeavour in the mid 1940’s. Today this introduced tree species from northern China
is found in Ontario, Quebec and most of the United States.
Another reason for updating this species list is the discovery of previously unknown
native plants species after the release of the OPL in 1998. This includes the addition of
Swamp Cottonwood [Populus heterophylla], discovered in Essex County; Dwarf
Dandelion [Krigia virginica] in Pinery Provincial Park, and Trailing Bush Clover
[Lespedeza procumbens] discovered in Haldimand County. There are still some regions
of the province that are poorly botanized and may still yield some new discoveries to our
botanical flora.
Some native species are disappearing from our flora as a result of the introduction of
fungal pathogens which have been detrimental to some of our native trees. Two species in
particular, American Chestnut (Castanea dentata) and Butternut (Juglans cinerea) are
disappearing due to the introduction of infectious microorganisms. Chestnut blight and
Butternut canker, along with a loss of suitable habitat have the potential to eliminate these
species from our flora. Other plants such as Ginseng (Panax quinquefolius) are
disappearing as a consequence of the over harvesting of its underground tubers.
As a result of these influences, the total number of species in Ontario will always be
fluctuating to some extent. At best all we can do is provide a listing of the observed
documented plant species, and continue to protect the varied habitats that are essential for
their survival.
iv
Nomenclature
The nomenclature used for this listing of 2,919 plant species (including subspecies,
varieties and hybrid forms) is aligned with the Integrated Taxonomic Information System
(ITIS). This website is a reference site that is utilized by many environmental
organizations and provides access to recently published plant nomenclature.
English (Common) names listed in this publication are from the ITIS website. For a
number of species the common name is derived from the NHIC or PLANTS databases.
There has been no attempt to correlate these names with local field guides or plant
manuals.
As plant nomenclature changes, printed species list become outdated with time. While
producing this publication, the ITIS website was accessed during a two month period (Jan
& Feb, 2013), making this plant list static in time. Some entries in the ITIS database will
have changed after this time period, thus making this species list slightly outdated before
it is published. However, for the 98% of the names that do not change, this publication
will still remain relevant and useable.
Do not be surprised if there is a difference in the nomenclature used by these databases
and the names found in this species list. As with political doctrine there is always some
disagreement as to which phylogenetic treatment or species name to use. For example a
common shrub found in wetlands and along the shoreline of lakes, Labrador Tea (Ledum
groenlandicum) is listed as Rhododendron groenlandicum in the VASCAN and FNA
databases. However, in the ITIS and NatureServe databases Labrador Tea is still listed as
Ledum groenlandicum. In reality both names convey a label for a specific plant form, and
both are valid names which are used to identify this species. It only becomes an issue
when the binomial in use becomes obscure, thus making it difficult to quickly transfer
knowledge relating to that plant species.
Additional References
The downside to these nomenclatural changes is the creation of multiple names for a
single plant species. There are two publications which provide an annotated list to most
of the older plant names which have been published in the past. Morton and Venn’s
Checklist of the Flora of Ontario (1990), is still very useful since it can be used to trace
the usage of older plant names. Likewise the Ontario Plant List (Newmaster, 1998) on
which this document was originally based, includes a listing of many of the synonyms
that have been published in the botanical literature.
For a listing of plant species found outside of the intended geographical range of this
publication check out web based resources such as the Northern Ontario Plant Database
(NOPD), Flora Ontario – Integrated Botanical Information System (FOIBIS) or Natural
Heritage Information Centre (NHIC).
Here are some other useful web sites which can be helpful when looking for references to
vascular plant names.

Species Code
For data entry in the field it is more efficient to write down (or enter) an abbreviated
code, rather than writing out the entire plant species name. It is much quicker to record
the code APOCANA for Spreading Dogbane, rather than writing out Apocynum
androsaemifolium ssp. androsaemifolium.
Each seven digit code is constructed by using the first four characters of the genus name
followed by the first 3 characters of the species name. Therefore, White Trillium
(Trillium grandiflorum) has the 7 digit code TRILGRA. If there is an additional
subspecies or variety ranking for a species, then the first two characters of the species
epithet are used and the third (last) character consists of the first letter of the subspecies
or varietal epithet. Winged Sumac (Rhus copallinum var. latifolia) has the code
RHUSCOL. All of the abbreviated codes produced for this listing are unique for each
species, subspecies and variety.
In situations where the 7 digit code generated is the same for two separate species, then
an alternate alphabetical character is used for the seventh digit of the code. For example,
Water Arum (Calla palustris) and Spring Water Starwort (Callitriche palustris) would
both produce the same seven character code. In this case the code CALLPLS is used for
Water Arum, and CALLPLU is used for Spring Water Starwort.
Here are some additional examples;
Common Lady Fern
Slender Loose-flower Sedge
Graceful Sedge
Plantain-leaf Sedge
Broad-leaved Sedge
Athyrium filix-femina var. angustum
Carex gracilescens
Carex gracillima
Carex plantaginea
Carex platyphylla
ATHYFIA
CAREGRA
CAREGRM
CAREPLA
CAREPLT
For plants which have had their names changed, the original seven digit code will remain
the same as before, with only the scientific name changing in the plant listing. For
example, Fireweed listed in the previous versions as Epilobium angustifolium, is now
listed as Chamerion angustifolium ssp. circumvagum. The 7 digit code EPILANG will
remain the same, even though this species has been placed into the genus Chamerion.
Often when new varieties are described for an existing species, the resulting code does
not match as it did before. For example Spotted Coralroot (Corallorhiza maculata) had
the code CORAMAC assigned to it. Now that there are two varieties listed for this
species, the original code of CORAMAC is still used for Corallorhiza maculata var.
maculata while Corallorhiza maculata var. occidentalis receives the code CORAMAO.
vi
The logistics of trying to go back to all of the exiting versions of these databases and
changing the plant species code is very cumbersome. Therefore the original codes
developed for a species takes precedence even though there have been recent
nomenclatural changes.
List of Synonyms
To make this third edition of the Southern Ontario Plant Species List more user friendly,
a list of synonyms has been included. When looking for Round-lobed Hepatica (Hepatica
americana) and not finding it in the main species list, then look in the List of Synonyms.
Here the name Anemone americana [ANEMAME] is cited, since this binomial is
currently used for this species.
If a species name is listed twice in the List of Synonyms, it is a result of genetic evidence
indicating that a species once thought of as a single species is actually two closely related
species. For example Maidenhair Spleenwort (Asplenium trichomanes) used to be
considered just one species. However it has been shown that one subspecies grows
specifically on calcareous bedrock, while the other subspecies if found on metamorphic
or igneous rock outcrops. Asplenium trichomanes is split into two separate subspecies
with Asplenium trichomanes ssp. quadrivalens growing on the Niagara Escarpment,
while Asplenium trichomanes ssp. trichomanes is found on the Canadian Shield.
SRank
The Natural Heritage Information Centre uses a ranking system that considers the
provincial rank of a species (element) as a tool to prioritize protection efforts. Provincial
(Sub-national) ranks are also known as SRANK. These ranks have been assigned using
the best available scientific information, and follow a systematic ranking procedure
developed by The Nature Conservancy. Sub-national ranks are based on three factors:
estimated number of occurrences, estimated community extent, and estimated range of
the community within the province. These provincial ranks are summarized below.
SH – Possibly Extirpated (Historical); species occurred historically and there
is some possibility that it may be rediscovered. Its presence may not
have been verified in the past 20-40 years
S1 - Extremely rare in Ontario; usually 5 or fewer occurrences in the province,
or only a couple remaining hectares
S2 - Very rare in Ontario; usually between 6 and 20 occurrences in the province,
or only a few remaining hectares
S3 - Rare to uncommon in Ontario; usually between 21 and 80 occurrences in the
province; may have fewer occurrences, but with some extensive examples
remaining
S4 - Considered to be common in Ontario. It denotes a species that is apparently
secure, with over 80 occurrences in the province
vii
S5 - Indicates that a species is widespread in Ontario. It is demonstrably secure
in the province
? - A question mark following the rank indicates that there is some uncertainty
with the classification due to insufficient information.
These provincial ranks may further be modified.
S2S3 - Indicates that an element is rare, but insufficient information exists to
accurately assign a single rank
SNR - Unranked — conservation status Not Ranked
SNA - Not Applicable – a conservation status rank is not applicable because
the species is not a suitable target for conservation activities
SX -
Indicates that an element is extirpated from the province
SU -
Indicates that the status is uncertain due to insufficient information
An additional rank not used by the NHIC.
SHY - Indicates that the species is of a HYbrid origin
(This rank is not used by the NHIC, but is included in this listing to
identify plant forms that are variable and are the result of
cross breeding)
Plant Form Codes
This column describes the general growth form of a plant species. Is it a forb, shrub or
tree?
Non vascular plants such as moss, liverwort, hornwort, algae and lichen have general
placeholder codes which are included in this listing. In the case of some rock barrens,
moss and lichen species are the dominate plant forms, so it is necessary to record a
percent cover for these non-vascular plant groups. If your organization has someone who
has expertise with non vascular plants or lichens, then identify them down to the genus or
species level whenever possible. Generally, most organizations estimate just one percent
cover value for all of the moss species combined together.
The following is a listing of the abbreviations used in the table along with a brief
explanation for each code.
