Checklist of the Vascular Plants of Saskatchewan - Native Plant ...

INTRODUCTION
This Annotated Catalogue of Saskatchewan Vascular Plants is a compilation of
the native and naturalized pteridophytes, conifers and flowering plants recorded in the
uncultivated flora of Saskatchewan. It represents an updating of the floral listings in
Harms (2003). Since publication of the latter, numerous taxonomic (and resultant
nomenclatural) changes have been proposed by recent revisionary studies, often with
molecular data inputs reinterpreting genetic relationships, and subsequently published
since early 2003 have been eight additional volumes of the presently ongoing Flora of
North America (FNA) series. Also, since 2003, the Biota of North America Project
(BONAP) (Kartesz & Meacham, 1999-2006) plant list has undergone revisions. To
remain relatively current, regional floral lists and manuals require periodic updating that
incorporates newly available taxonomic information.
Most recently proposed taxonomic revisions with their associated name changes
have been accepted in this catalogue, especially if included in published volumes of the
Flora of North America (FNA), or alternatiovely by the Biota of North America Project
(BONAP) (Kartesz & Meacham, 2006). But, when personal experience with regard to
particular plant groups contradicted recent innovations, my preferred alternative
taxonomic interpretations are followed in this catalogue.
In this catalogue, the plant families are alphabetically arranged under the
following three major vascular plant groups: I. Pteridophytes (Fern Allies and True
Ferns); II. Gymnosperms: Conifers (Cone-bearing Naked-seed Plants); and III.
Angiosperms (Flowering Plants). In turn, the genera, species, subspecies, and varieties
are listed alphabetically under their respective families. Taxonomic forms (formae) are
not included. For each taxon entry, the accepted scientific name is given with its
authorship, followed by its common name(s). With non-standardization of plant common
names, various ones may be used for any one species, and the more frequent ones are
given here. A more comprehensive listing of common names is provided in Harms
(2003). Listed in square brackets following the common names, are the more important
scientific synonyms with their authorships, allowing for the interconnecting and
interrelating of alternative names for taxa that may be found in presently used floral
manuals and reference sources. More comprehensive synonomy lists are found in Harms
(2003). Cross-referencing is provided for alternate names often used in more recent
literature for genus-level name changes, although nor for changed species’ epithets within
a genus which the listed synonyms should help to clarify.
Finally, following the synonymy list for each listed taxon, brief status indicators
are given using the following abbreviations as defined below for presence/origin status,
and for rarity/abundance status:
Presence and Origin Indicators:
N -- native taxa: the indigenous or original species in Saskatchewan prior to
European settlement.
In -- naturalized exotic taxa (broadly defined as all non-native plant taxa, whether
