Discussion

Lupinus dalesiae is known only from the high Sierra Nevada in Plumas County. It is distinctive with its white pubescence, yellow flowers, and banner that is hairy abaxially.

P. A. Munz (1959) treated Lupinus dalesiae as a synonym of L. adsurgens var. undulatus C. P. Smith, but L. adsurgens has a banner that is glabrous abaxially.
