Castilleja nervata is a common and widespread Mexican species, from northern Chihuahua and Sonora south to central Oaxaca. It has medicinal value to indigenous peoples of the Sierra Madre. In the flora area, C. nervata is known from a single, presumably extant population in the Chiricahua Mountains in Cochise County, though there are historical records from the Rincon and Santa Rita mountains. The sole recently verified population is on private property and is endangered.
