Discussion | Dalea tenuis is largely a species of central Texas occurring as far east as McLennan County and south to Bandera County. (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.) |
