Discussion

Dalea feayi occurs in xeric soils and generally does not grow in the same habitats as D. carnea. In Florida, the species is frequent in the peninsula and central panhandle regions.

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

Dalea enneandra is native to the Great Plains and as far east as the Texas coast and the loess hill prairies of western Iowa and northwestern Missouri. It is naturalized in DuPage County, Illinois. Its persistent calyx aids in wind dispersal of fruit.
