Discussion | Lupinus constancei is known from only two populations in the Lassics Range (Inner North Coast Range) in southeastern Humboldt and northwestern Trinity counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Lupinus sericeus is widespread and common from the southern interior mountains in British Columbia and southwestern Alberta southward to eastern Washington and eastern Oregon to northern New Mexico and northwestern Arizona, northeastern Nevada through Idaho and Wyoming to the Black Hills in South Dakota. Plants with creamy or white flowers in southeastern Washington are known as subsp. asotinensis. D. Isely (1998) recognized this taxon based on petal color and distribution, but since white and yellow flowers occur throughout the range of Lupinus sericeus, it is not formally recognized here. Lupinus pureriae C. P. Smith may be a hybrid derived in part from L. sericeus, according to an annotation by D. B. Dunn on the holotype (CAS0008254).
