Narrative
One cycle of phenotypic recurrent selection for plant height, density of foliage cover, and rhizomatous spread at Mandan, ND. Plant vigor greater than Flintlock or Walsh, similar to ND-WWG931, and less than Barton, Rodan, or Rosana. Similar to ND-WWG931 for foliage density, however, its rate of rhizome production was 10% less. Matures four days earlier than ND-WWG931

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
