Description
"Only the slightly more ascending pedicels and usually entire or subentire leaves serve to distinguish this [A. selbyi] from A. perennans. Possibly, it would be treated better at infraspecific level within that species." (Welsh et al. 1993)
Distribution
It appears to be a Colorado Plateau endemic. Western Colorado and southwestern Wyoming to northwestern New Mexico and eastern Utah (Rollins 1993); Carbon, Daggett, Duchesne, Emery, Garfield, Grand, Kane, San Juan, Sevier, Uintah, Utah, and Wayne counties; western Colorado and northwestern New Mexico (Welsh et al. 1993).
Habitat
Sandy knolls, steep hillsides, among sagebrush or under junipers and pines, rocky slopes, base of sandstone cliffs, chip-rock (Rollins 1993); sagebrush, pinyon-juniper, mountain brush, ponderosa pine, and Douglas fir communities mostly at 1,500 to 2,625 m elevation (Welsh et al. 1993); common, pinyon-juniper and sagebrush (Weber & Wittmann 1996).
