Narrative

Pascopyrum smithii (Rydb.) Barkworth & D. R. Dewey

Genus:

Pascopyrum

Family:

Poaceae (alt. Gramineae)

Subfamily:

Pooideae

Tribe:

Triticeae

Nomen number:

102367

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.
