Rank Reasons
Endemic to central and southern Cascade Mts., Klamath ranges in southwestern Oregon and northern California. This species was described as uncommon in California (Hickman 1993). It grows on open, rocky, cliff faces so surveying is difficult but because of this, sites are self-protecting. Considered rare in Oregon until a botanist who was also a rock climber observed it in numerous rock climbing expeditions.
