Working List of Invasive Vascular Plants of Wyoming ─ III (Vernacular names from selected major works) Dec 2017
Compiled by R.L. Hartman and B.E. Nelson With assistance from R.D. Dorn, W. Fertig, B. Heidel
The following list contains 372 taxa introduced to Wyoming from outside North America; included are invasives recognized by the Wyoming state government as noxious (; 28; although Ambrosa tomentosa is native). A number of these species repesent escapes from cultivation and are limited to one or a few collections. Nomenclature is based on R.D. Dorn, 2001, Vascular Plants of Wyoming; where updated, Dorn’s synonyms are in square brackets [ ]. Other synonyms found in the list of sources below are not included. Likewise, family names and their circumscriptions follow Dorn; where defined differently by the Angiosperm Working Group IV (APG IV), clarification follows in parenthese. Dorn does not indicate the typical variety or subspecies unless a second infraspecific taxon is recognized. We have included the typical infraspecies where appropriate. The lack of hyphenation, word separation, or capitalization may not reflect the appearance of the vernacular names in the works cited.
