Erythronium grandiflorum
Of conservation concern.
This species is endemic to the Coast Ranges of western Oregon.

Subspecies 2 (2 in the flora).
This beautiful species is often very abundant in mountain meadows of western North America, especially in the Rocky Mountains, where it may form spectacular displays. It is often difficult to grow in cultivation outside its preferred habitats. Bulbs of this species were a staple food for native North American peoples of several tribes, and were eaten in large quantities and also traded. Within the typical subspecies, both anthers and pollen vary considerably in color; plants with pale anthers have been called var. pallidum, and forms with yellow anthers, var. chrysandrum. Plants possessing very short stigma lobes and lacking auricles on the tepals have been recognized as var. nudipetalum, but they do not appear sufficiently distinct to warrant taxonomic recognition and may simply represent depauperate forms.
