Discussion | Lupinus hyacinthinus is found in southern California in the San Gabriel, San Jacinto, and Santa Rosa mountains and on the Sierra San Pedro Mártir in Baja California. It is distinguished from its close relatives by its larger flowers in combination with green (versus gray or dull green) leaves.

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.
