Notes Glossary
  • Rediscovered on Carrizo Plain by David Keil in 1992. Also found at Lawrence Livermore Laboratory Site 300, ALA Co. in 1997. Historical occurrence for SJQ Co. from literature lacks documentation; occurrence from La Panza, SLO Co. (244C) probably misidentified E. lemmonii ssp. lemmonii. Threatened by agriculture and grazing. See Madroño 47(2):138 (2000) for ALA Co. occurrence information and 50(1):1-7 (2003) for population characteristics information.
