Variety parishii was last seen in 1980 in the Whittier Narrows Nature Center of Los Angeles County. It is known from about five historic locations including the San Gabriel River, San Bernardino Valley, and the Lexington Wash near El Monte, Los Angeles County. According to the California Native Plant Society (http://www.cnps.org/inventory), it was probably extirpated due to a combination of dry years, altered stream flows, fires, habitat loss, and invasive species.
