Discussion | Calochortus howellii is known only from the Illinois River valley, Josephine County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
recent collections of calochortus longebarbatus from oregon exhibit intergradation in the characters that heretofore have been thought to distinguish the following two varieties (k. l. chambers pers. comm.), and their continued recognition may prove unwarranted Varieties 2 (2 in the flora).
