Notes Glossary
  • Rare at all occurrences, and seriously threatened by grazing; reduced to one plant on ANA Isl. One occurrence introduced on SMI Isl. (SMIE); historical, presumed extirpated occurrence on SNI Isl. is not native. May not be native to SRO Isl.; plants on mainland, SCZ Isl., and Todos Santos Isl. (BA) most likely planted. Recovery efforts ongoing on ANA Isl. See L. assurgentiflora in The Jepson Manual. See The California Islands: Proceedings of a Multidisciplinary Symposium, pp. 175-178 (1980) for species account.
