Notes: Threatened by development, foot traffic, grazing, recreational activities, and vehicles. Possibly threatened by alteration of fire regimes and non-native plants. Easily confused with E. davidsonii; possibly overlooked. See E. foliosum in The Jepson Manual (1993). Most occurrences not seen recently; need field surveys. See Phytologia 86(3): 133 (2004) for original description, and Madroño 59(3):150-155 (2012) for information on rediscovery. |
