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.) |
Dalea obovata occurs in the southern coastal plain of Texas as far north and west as Frio, Medina, and Travis counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
