It is found in the American states of Arizona, California, Nevada, New Mexico, Texas and Utah, as well as in the countries of Argentina, Chile, Mexico and Peru.

Regni Veg. Vol.21 on page 249 in 1925. Then in 1927, Ivan M. Johnston wrote that the genus of ''Oreocarya'' (in the Boraginaceae family) could be combined with ''Cryptantha''.
