Selaginella hansenii is one of the four native endemic species of the Tetragonostachys in California. The other three are: asprella, bigelovii, and cinerascens. Unlike the other endemics, S. hansenii is a Sierran species. Supposed populations found in the eastern watershed of the South Coast Ranges of Kern County are input errors of a collection made in the area of Black Mountain south of Table Mountain in eastern Kern County, not western Kern County! Possibly in this area:

Its range of occurrence overlaps that of S. bigelovii in Tulare County.
