Discussion

Dalea foliosa is rare and in 1991 was designated federally as endangered. At that time, there were 14 known populations, only four of which had state or Nature Conservancy protection. The species is in the Center for Plant Conservation’s National Collection of Endangered Plants.

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.
