Discussion | camassia quamash is highly variable morphologically. although there tend to be distinct geographical variants. here recognized as subspecies following f. w. gould (1942), there is much overlap among them. the subspecific status of these taxa is retained to highlight the extreme morphological variability and geographical patterns within the species. a detailed biosystematic study of this complex is needed Subspecies 8 (8 in the flora).

Of conservation concern. Camassia howellii flowers one to two weeks later than sympatric populations of C. leichtlinii. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
