FWS Digital Media Library — The U.S. Fish and Wildlife Service’s National Digital Library is a searchable collection of selected images, historical artifacts, audio clips, publications, and video.The plant was federally listed as a threatened species in 1995. It is considered threatened due to loss of surrounding habitat to recreational activities, to competition from invasive plant species, to its proximity to a dense population center, and to its confinement to a single population of plants. The population grows on land owned by the Marin County Open Space District, an area previously owned and preserved by The Nature Conservancy. It was first brought to the attention of science in 1971, and was described to science in 1973. It is protected along with a number of other rare serpentine soils endemics that grow on and around Ring Mountain.
