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 sabinalis was first found at the entrance to Sabinal Canyon in Bandera County, but collections are known also from nearby Uvalde and Val Verde counties; it has not been collected since the 1950s, and no extant populations are known.
