Dalea phleoides
Dalea compacta
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 compacta is most abundant in east Texas, where it is found in habitats similar to those occupied by D. purpurea in prairies of the mid United States.
