Discussion | Lupinus arizonicus occurs in the eastern Mojave and Sonora deserts of southeastern California, southwestern Arizona, and southern Nevada, plus adjacent areas in northern Mexico. Robust plants have been named var. barbatulus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Lupinus padrecrowleyi is known from the southern Sierra Nevada, mostly on the east slope, in Inyo, Mono, and Tulare counties. Lupinus padrecrowleyi can easily be distinguished from other Lupinus species by its usually white-woolly leaves, both clustered at base and along the stem, banners that are hairy abaxially, glabrous keels, and cream to yellow flowers.
