Discussion:D. virgatus [var. virgatus] auct. pro parte The west Texan forms of D. virgatus are poorly differentiated morphologically from the typical tropical D. virgatus (Turner, 1950b and 1950c). But they are considerably disjunct from the latter which is primarily of southeastern coastal Mexico and south, thus adapted to a rather different climatic regime. Turner’s segregation seems justified. Desmanthus virgatus, presumedly meaning var. virgatus is included in the Arizona flora by Kearney and Peebles (1960). Part of their material is C. covillei but two gatherings from a single location (early 1940’s) are of suffrutescent D. virgatus and can reasonably be referred to var. glandulosus. Turner (1950b) also cites var. glandulosus from a Dona Ana Co., New Mexico location. Further collecting, in northern Mexico and adjacent United States, may bring further populations to light. Small (1933) recognized both Acuan depressum and A. virgatum from Florida, but Long and Lakela (1971) take up only D. virgatus var. depressus. Small’s material (NY) includes two sheets which I would consider var. virgatus, but there are no modern collections. Probably these (Small’s plants) represent waif introductions from the West Indies.
