[wikipedia] Range, Rarity: Distribution The plant is endemic to California, where it is known from the Inner Northern California Coast Ranges and Southern Sierra Nevada foothills. Southern Sierra Three recent occurrences in the southern Sierra, all of which may have been extirpated by now.[3] The plant was thought extinct in the southern Sierra until it was rediscovered at one site in Tulare County in 1992. This site, which was located on private land, has since been converted for orange groves, possibly eliminating the plant.[4] The owner of the land has not allowed any searches for the plant since then, but the area is considered critical habitat for this federally listed endangered species.[4] (contributed by Mary Ann Machi)
