Discussion

Dalea foliosa is rare and in 1991 was designated federally as endangered. At that time, there were 14 known populations, only four of which had state or Nature Conservancy protection. The species is in the Center for Plant Conservation’s National Collection of Endangered Plants.

Varieties 2 (2 in the flora).

Varieties candida and oligophylla were treated as separate species by D. K. Wemple (1970) and are fairly well defined. In regions of overlap, var. oligophylla normally occupies higher, drier sites than var. candida.
