Howell's Mariposa Lily/ Howell Mariposa Tulip/
(Calochortus Howellii)

Habitat Howell’s mariposa lily is typically found on dry, rocky slopes with serpentine derived soils in the Illinois River valley. These soils are wet in early spring as plants emerge, but dry quickly as the season progresses. Vegetation is sparse and associated species include Pinus jeffreyi, Calocedrus decurrens, Arctostaphylos viscida, Ceanothus pumilus, Eriophyllum lanatum, Allium amplectens, and Triteleia hyacinthina.

Range Populations of Calochortus howellii are concentrated along the Illinois River drainage in southwest Oregon. The northernmost occurrence is located a few miles west of Selma, with populations extending south along the Illinois to within a few miles of the California border. This species has not been reported from California.
