Discussion

Variety albifolius was described as an elongate, ungainly, trailing or scrambling halophyte (D. Isely 1998); it occurs at the eastern base of the Sierra Nevada in Inyo County near Big Pine and Lone Pine, near Muroc in Kern County, and near Lancaster in Los Angeles County.

Astragalus albifolius (M. E. Jones) Abrams is an illegitimate later homonym of A. albifolius Freyn & Sintenis 1893.
