Discussion

Chylismia munzii is known from middle elevations in the mountains at the north end, eastward from, and south of Death Valley, from Saline Valley and the Grapevine Mountains, Inyo County, California, and Yucca Flat, Nye County, Nevada, southward to the Kingston Range, San Bernardino County, California.P. H. Raven (1962, 1969) determined this species to be self-incompatible. It sometimes hybridizes with C. brevipes subsp. brevipes and C. claviformis subsp. aurantiaca.
