There are several subspecies, including G. c. ssp. arenaria, the sand gilia or Monterey gilia, which is federally listed as an endangered species. It is known from about 24 occurrences around Monterey Bay. [1] Hoffmann's slender-flowered gilia, ssp. hoffmannii, is also federally endangered and is limited to Santa Rosa Island, one of the Channel Islands of California. [2]
