Type: “Hab. in Armeniâ Rossicâ vel Persiâ bor. (Szow!)”.

Holotypus: AZERBAIJAN: “Armenia”, s.d., Szovits s.n. (G-BOIS [G00154035]; iso-: GH [GH00283045], K [K000693833], LE) .

= Erysimum hajastanicum Wissjul. & Bordz. in Bull. Jard. Bot. Kieff 12–13: 125. 1931.

Notes. – POLATSCHEK (2011: 423) lectotypified E. brachycarpum based on the G-BOIS duplicate above, whereas DOROFEYEV (1987: 1539, 2012: 403) lectotypified the name twice based on one of two sheets at LE. However the specimen of G-BOIS is recognized herein as the holotype because it was the sole sheet on which the species description was based.

The status of E. brachycarpum has fluctuated a great deal among authors or sometimes by the same author. It was recognized as a distinct species (BUSCH, 1939; AVETISIAN, 1966; POLATSCHEK & RECHINGER, 1968; DOROFEYEV, 1987, 2012), as a synonym of E. chazarjurti N. Busch (POLATSCHEK, 2011), or a synonym of E. hajastanicum (GERMAN, 2014) . For a thorough discussion on the problem, the reader is advised to consult the last reference.
