Narrative
Rhizomatous and forms dense blue-green sward. Leaves less heavily veined and thinner than other western wheatgrass cvs. Average yield of 200 kg/ha more forage than other western wheatgrass cvs. Similar to Rosana in area of adaptation but more productive than Rosana on coarse- textured soils. Seed has short awn that distracts from seed quality but is similar to Rosana in seed yield. Moderate to good resistance to stem rust (Puccinia graminis)

Place of publication:

Amer. J. Bot. 72:772. 1985 (Á. Löve, Taxon 29:168, 547. 1980, nom. inval.)
Comment:
Löve failed to provide a description or diagnosis on p. 168, so the genus Pascopyrum was not validly published until a later issue (p. 547), when he then failed to fully cite a basionym for P. smithii
