Discussion | Lupinus shockleyi occurs in the desert areas of southern California, adjacent areas of southern Nevada, and northwestern Arizona. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Lupinus andersonii is found widely in regions of the Sierra Nevada in California and western Nevada plus adjacent areas of southern Oregon. The erect branching with puberulent leaflets and a banner that is glabrous abaxially distinguish it from L. angustiflorus, L. apertus, and L. padrecrowleyi, which have pubescence at least on the abaxial crest of the banner. According to P. A. Munz (1959), L. egressus C. P. Smith may be of hybrid origin (L. fulcratus × L. andersonii). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
