Discussion | 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.) |
Dalea multiflora shows considerable geographic variation in stature. Its floral structure is similar to that of D. candida var. candida, and individuals intermediate between the two species occur (R. C. Barneby 1977c). In Texas, D. multiflora is known from the eastern two-thirds of the state. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
