Discussion

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).

Coastal plants of Calochortus luteus are mostly triploid, while those of the interior are mostly diploid. Occasionally this species hybridizes with C. superbus.
