Discussion | 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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Dalea wrightii occurs in southeastern Arizona, southern New Mexico, and trans-Pecos Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
