Thinly pubescent or glabrate, the stems mostly <1 dm, the peduncles most often 0, rarely well developed at some nodes; lf-formula and lft-size as given in the key to varieties; lfts often well separated along pinna- rachis; color of androecial tassel scarcely known.

In habitats of var. humilis but of narrower range in and around the margin of the Gila Basin in Arizona and s.-w. New Mexico, thence s. along the w. and s. margins of the Mexican Plateau to Jalisco, n. Mexico, w. Hidalgo, and (reportedly, Standley, 1922: 387) Puebla. — Map 10. — Fl. VI-IX.
