Discussion

Subspecies yumae is known from southeastern Imperial County, California, Yuma Desert, Arizona, and from El Gran Desierto to Puerto Peñasco in northwestern Sonora, and in northeastern Baja California. The subspecies is probably from hybridization between subspp. aurantiaca and peirsonii; it intergrades with subsp. aurantiaca and rarely hybridizes with Chylismia brevipes subsp. arizonica.
