Discussion

Subspecies peeblesii is known throughout almost all the southwestern half of Arizona and locally in northwesternmost Sonora, and was recently collected in Grant and Hildago counties in New Mexico. It intergrades with subspp. aurantiaca and rubescens, and hybridizes with all subspecies of Chylismia brevipes.
