Notes



Move to List 4? Location, rarity, and endangerment information needed, especially quads for FRE and TUL counties. Many misidentifications of Sequoia-Kings Canyon NP plants. See Bulletin of the California Academy of Sciences 1:117 (1885) for original description, Phytoneuron 2012-39:1-60 (2012) for revised nomenclature, and Phytoneuron 2012-42:1-4 (2012) for taxonomic treatment.
