Discussion | Dalea scariosa is a geographically restricted and beautiful plant that is known only from locations near Alburquerque and Belen. It appears to be related to two other rare taxa, D. bartonii and D. sabinalis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
