Discussion | Dalea foliosa is rare and in 1991 was designated federally as endangered. At that time, there were 14 known populations, only four of which had state or Nature Conservancy protection. The species is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 9 (1 in the flora). R. C. Barneby (1977c) recognized nine varieties in Dalea carthagenensis, a complex and polymorphic species. The eight varieties found outside the flora area occur in Mexico, West Indies, Central America, and South America. The calyces of D. carthagenensis sometimes have slightly hooked lobes when mature, a feature used to distinguish D. scandens; the two species are allopatric.
