Discussion | Of conservation concern. Calochortus umpquaensis is known only from Watson and Ace Williams mountains on both sides of the Little River, Douglas County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Calochortus coeruleus appears to intergrade with C. tolmiei to some extent, especially in petal ciliation (K. L. Chambers, pers. comm.), and it might better be treated as a variety of the latter, more widespread species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
