Dalea phleoides
Dalea candida
Varieties 2 (2 in the flora).
B. L. Turner (2013) divided Dalea phleoides into three species: D. phleoides, distinguished from D. drummondiana by longer leaf blades and calyces, and D. carrizoana, based on the absence of indument and an allopatric distribution (from DeWitt to Maverick counties) south of the range of the other two species; the latter two are treated here as synonyms of D. phleoides var. microphylla.

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.
