Systematics of the tribe Orcuttieae (Gramineae) and the description of a new segregate genus, Tuctoria

Systematics of the tribe Orcuttieae (Gramineae) and the description of a new segregate genus, Tuctoria

American Journal of Botany 69(7): 1082-1095

The 2 genera Neostapfia and Orcuttia are treated as sole members of the tribe Orcuttieae. Results of field studies and examination of 550 herbarium spp., chromosome counts and seed protein analyses for the monospecific Neostapfia and the 8 Orcuttia taxa are presented. It is concluded that the 6 spp. and 2 var. of Orcuttia should be all considered as separate spp. and divided into 2 genera.
