Discussion | Varieties 5 (5 in the flora). Various authors have differed in their circumscriptions of Lupinus latifolius. For example, P. K. Vaughn and D. B. Dunn (1977) recognized three varieties, D. Isely (1998) recognized six varieties, and C. L. Hitchcock et al. (1955–1969, vol. 3) recognized three varieties. The most conservative approach has been taken here by recognizing taxa that have the clearest characteristics, but that approach might not reflect phylogeny. Research is needed to clarify the varieties and particularly the relationships among L. latifolius and L. arcticus, L. perennis, and L. polyphyllus. Lupinus latifolius is known to cause birth defects in livestock (R. F. Keeler et al. 1977). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Lupinus affinis is mostly a coastal species that occurs from the San Francisco Bay region northward to Lane County, Oregon. Lupinus affinis intergrades with L. nanus and can be confused with L. littoralis var. variicolor, a perennial species with a toothed keel.
