Discussion | Plants of Dalea pulchra are attractive in flower. The spikes shatter quickly at anthesis; legumes and seeds are seldom seen. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
