Discussion | Triphysaria micrantha is known from central California from the coast to the Sierra Nevada. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Triphysaria floribunda is known from the San Francisco Bay area. The species is threatened by grazing, non-native plants, and trampling (California Native Plant Society, http://www.rareplants.cnps.org); only 14 of the 150 specimens for T. floribunda in the California Consortium of Herbaria portal (http://ucjeps.berkeley.edu/consortium) were collected after 1971.
