Draba mogollonica Greene, Bot. Gaz. 6: 157. 1881. TYPE: U.S.A. New Mexico, Mogollon Mts, 18 Apr 1880, Edward L. Greene s.n. (holotype, NDG). No specimen with that date has been located at NDG. Instead, an excellnt specimen dating 20 April 1880 is in that herbarium, with a duplicate at MO. It is likely that the date given in the original publication is an error. If so, then the sheet at NDG with the 20 April 1880 collection must be the holotype. A duplicate at K exists but the collection date is 19 Apr 1880.

Stems (6–)12–28(–36) cm, usually few branched, pubescent proximally with a mixture of simple trichomes 0.3–1.3 mm and 2–4-rayed trichomes 0.1–0.6 mm, glabrous distally.
