Erysimum pallidum Boiss., Fl.

AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 44

Erysimum pallidum Boiss., Fl. Orient. 1: 207. 1867.

Type: “Hab. in rupestribus regionis alpinae Lyciae supra Elmalu (Bourg!)”.

Holotypus: TURKEY: “In rupestribus regionis alpinae montis Elmalu”, 26.V.1860, Bourgeau s.n. ( G-BOIS [ G00154049 ]; iso-: K [ K000075601 ], P [ P02272748 ]) .

= Erysimum kotschyanum J. Gay, Erysim. Nov.: 5. 1842.

Notes. – The three duplicates above fully agree with the protologue and all were collected on the same date. Boissier based the species description solely on the unicate in his herbarium, and that specimen has to be taken as the holotype, instead of lectotype as listed by YILDRIMILI (2008: 14).

POLATSCHEK (2011: 406) erroneously listed an entirely different collection with a label that reads: “ E. Bourgeau – Plantae Lyciae 1860. Erysimum kotschyi J. Gay (Boiss.) In cacuminibus regionis alpinae montis Elmalu, 9 Jun.”, designated the W duplicate as the lectotype, and listed specimen in G-BOIS, GOET, and K as the duplicates. There are no such duplicates in G-BOIS or K, and Boissier never examined such a collection for this species .

Furthermore, the material collected on 26 May was distributed under the name E. pallidum whereas that collected on June 9 was distributed as E. kotschyi . All these factors collectively show some inaccuracies in designating a type. Since Polatschek examined the holotype of E. pallidum , it is surprising that he considered the two mixed collections as one.
