Deerweed in the desert

Acmispon glaber is a member of the Fabaceae (Pea) family. It is considered a pioneer species that will be one of the first to appear in disturbed areas. Like many members of its family, it has nitrogen-fixing root nodules that nourish the soil. Organic matter from the plant will fall and decompose, creating a more nutrient-rich layer of soil for other plant life.  Pipes Canyon | May 26, 2010
