Dalea phleoides
Dalea grayi
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.

Dalea grayi occurs in southeastern Arizona as far northwest as Gila County and far southwestern New Mexico (Grant and Hidalgo counties).
