Many sites likely extirpated; need current information on rarity and endangerment. Need quads for COL Co. Threatened by development, trampling, road construction, and vehicles. See Manual of the Botany of the Region of San Francisco Bay, p.100 (1894) for original description, and Brittonia 32(1):55 (1980) for revised nomenclature.
