Discussion

In Texas, Lupinus concinnus is known from the trans-Pecos region; in California it is more common in the central and southern areas.

Lupinus concinnus is a highly variable, predominantly self-pollinated complex and the named varieties cannot be consistently segregated. Desert plants with linear, coarsely hairy leaflets and few, minute cilia on lower keel margins (at times recognized as var. desertorum) may be confused with L. sparsiflorus.
