Draba aucheri Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 166. 1842.

Type: “[Aucher-Eloy] N. 92, Alpes Zerdkou”.

Holotypus: IRAN: “in Zerdakou”, s.d., Aucher-Eloy 92 (G-BOIS [G00332072]; iso-: G [G00441255, G00441256], K [K000729819], P [P00747370, P02272365]) .

Notes. – Boissier did not examine or annotate any of the sheets at P or G and based the species solely on the duplicate in his herbarium.

Three species names were published by Boissier and compete for recognition: Arabis sulphurea (see under that genus) was a renaming of Draba aucheri in Arabis, Draba linearis (next entry) was simultaneously published with D. aucheri (BOISSIER, 1842b), and SCHULZ (1927: 316) reduced it to a variety of D. aucheri . Subsequent authors, including myself, have since placed both D. linearis and Arabis sulphurea in synonymy of Draba aucheri . Oddly enough, Boissier recognized the very same species as Arabis sulphurea (Fl. Orient. 1: 173–174) and as Draba linearis (Fl. Orient. 1: 303).

The single species recognized here has yellow flowers, a feature taxonomically important in Draba, though it is never found in any species of Arabis .
