Discussion

Variety adenopoda is known from peninsular Florida as far north as Seminole County.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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.
