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.) |
Varieties 5 (1 in the flora). In addition to var. paucifolia, R. C. Barneby (1977c) recognized four varieties from Mexico to the Caribbean region and Central America. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
