Discussion

Dalea gattingeri is a narrow habitat specialist that can be locally common in suitable habitat.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Dalea bartonii is known only from the type locality in Brewster County, although a vegetative specimen from adjacent Terrell County was annotated as D. bartonii by B. L. Turner.

Dalea bartonii was assigned by D. K. Wemple (1970) to D. sabinalis (as Petalostemon sabinalis), but R. C. Barneby (1977c) considered it closer to D. scariosa and could not readily accommodate it in his concept or either D. scariosa or D. sabinalis. The known specimens were collected in July but were in late flower and early fruit, indicating that the peak of bloom was earlier.
