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
Verified:
11/09/2007 by ARS Systematic Botanists.
