Discussion

Lupinus brevicaulis resembles L. flavoculatus except that its flowers are smaller.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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.
