Dalea foliosa
Dalea leporina
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.

Dalea leporina has the broadest range of any member of Dalea, from the interior of the United States and Mexico to Costa Rica, and is disjunct in the Andes Mountains of South America. It varies in some characters, most of which were regarded by R. C. Barneby (1977c) as trivial or not taxonomically useful. It has been found on occasion as a weed far east of its range, for example, in Massachusetts (D. E. Snyder 1950).
