INTRODUCTORY
ABBREVIATION:PASSMI SYNONYMS:
Agropyron smithii Rydb. [61,66,97] NRCS PLANT CODE:PASM COMMON NAMES:
western wheatgrass TAXONOMY:The fully documented scientific name of western wheatgrass is Pascopyrum smithii P.A. Love (Poaceae) [12,86]. There has been much confusion concerning the taxonomy of western wheatgrass [12,13,14,41,42,43,64,77,78]. It is believed to be the product of an allo-octoploid (2n=56) derived from hybridization of 2 tetraploid grasses (2n=28); thickspike wheatgrass (Elymus lanceolatus) and beardless wheatgrass (Pseudoroegneria spicata ssp. inerme) [111]. Barkworth and Dewey [12] recognize the monotypic genus Pascopyrum A. Love. Ecotypes of western wheatgrass vary in forage and seed production characteristics and in color, coarseness, and competitiveness [68]. LIFE FORM:graminoid FEDERAL LEGAL STATUS:No special status OTHER STATUS:no entry AUTHORSHIP AND CITATION:Tirmenstein, D. (1999, July). Pascopyrum smithii. In: Remainder of Citation
