Notes

Move to List 1B? Plants from SHA and THE Co. may be different taxon; needs study. Occurrence on 608C needs confirmation. Threatened on private lands by logging and development. Other threats include vehicles, road maintenance, recreational activities, alteration of fire regimes, erosion, non-native plants and overshading. See Leaflets of Western Botany 1:55 (1933) for original description as F. phaeanthera, and MadroƱo 25(2):93-100 (1978) for revised nomenclature.
