Known only from the Shasta Lake region. Threatened by Shasta Dam raise and reservoir enlargement. Possibly threatened by road maintenance, mining, alteration of fire regimes, and non-native plants. Previously identified, and similar to, E. alsinoides and E. pulsiferae. Also similar to E. ampliata, an Idaho endemic that is hypothesized to be its closest relative. Not in TJM 2. See Phytoneuron 2013-43:1-10 (2013) for original description.
