Dalea leporina
Dalea laniceps
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).

In the flora area, Dalea laniceps is limited to the southeastern area of trans-Pecos Texas.
