Discussion

Varieties 9 (1 in the flora).

R. C. Barneby (1977c) recognized nine varieties in Dalea carthagenensis, a complex and polymorphic species. The eight varieties found outside the flora area occur in Mexico, West Indies, Central America, and South America. The calyces of D. carthagenensis sometimes have slightly hooked lobes when mature, a feature used to distinguish D. scandens; the two species are allopatric.

Varieties 3 (3 in the flora).

Dalea pinnata, with its headlike spikes and conspicuous involucres, resembles a member of the Asteraceae. This resemblance is heightened after the petals drop because the slender, plumose calyx-lobes begin to resemble a pappus.

The varieties of Dalea pinnata have limited geographical overlap and var. pinnata is the most widespread.
