Discussion | 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.) |
The ranges of Dalea searlsiae and D. flavescens overlap only in a small area of south-central Utah and north-central Arizona. In California, D. searlsiae is known from the Inyo and White mountains and other desert mountains in the southeastern part of the state.
