Calochortus lyallii

Calochortus lyallii, or Lyall's mariposa lily, is a North American species of flowering plant in the lily family. It is native and endemic to Province of British Columbia in western Canada, as well as the State of Washington in the northwestern United States. It only grows east of the Cascade crest in the mountains and foothills, and though its numbers are apparently secure in Washington, it is considered to be a blue-listed species in Canada- blue-listed taxa are at risk, but are not extirpated, endangered or threatened. It is found in dry to mesic open forest at lower to middle elevations in the mountains, commonly found with Pinus ponderosa (Ponderosa pine), Pseudotsuga menziesii (Douglas fir), Calamagrostis rubescens (pinegrass) and Carex geyeri (elk sedge). rdf:langString
