Taxonomic Comments
There are two varieties based on flower color only. Neither Kartesz's 1999 synthesis nor Cronquist's Intermountain Flora (1997) recognizes the varieties. Roxanne Bittman concurs (1998), adding that California's Jepson Manual only recognizes the full species. FNA (vol. 13, 2024) recognizes two varieties of Cymopterus ripleyi.

Range Extent250-20,000 square km (about 100-8000 square miles)
Number of Occurrences21 - 80
Rank Reasons
Cymopterus ripleyi is known from about 50 sites in southern Nevada, and also from fewer than six extant occurrences in Inyo County, California. Grazing is a threat to this taxon.
Range Extent Comments
Inyo County, California, and Nevada (Skinner, 1997). In southern Nevada, in Nye, Lincoln, and Esmeralda Counties (Kartesz, 1988).
Occurrences Comments
About 50 sites documented in Nevada, with additional suitable habitat unsearched. Known in California from six occurrences; three have been observed in the last twenty years (California Natural Diversity Database, May/1998 report).
Threat Impact Comments
Threatened by cattle grazing on Bureau of Land Management at Lee Flat (Skinner, 1997).
