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 ornata is nearly endemic to the Columbia-Snake river basin. In California, the species is known only from the Shaffer Mountain region in Lassen County.
