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.) |
Plants of Dalea pulchra are attractive in flower. The spikes shatter quickly at anthesis; legumes and seeds are seldom seen. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
