Arabis carduchorum 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 : 28

Arabis carduchorum Boiss., Fl. Orient. 1: 173. 1867.

Type: “Hab. in summo jugo Agerowdagh Armeniae Kurdicae inter Van et Müküs alt. 12000' (Ky!)”.

Lectotypus (designated by VITEK et al., 2018: 228): TURKEY: “Plantae in Karduchia ad Agerow Dàgh lectae. Crescit in summo jugo inter Wan et Müküs”, 12000' [3660 m], IX.1859, Kotschy 747 ( W [ W0050692 excl. plant in the middle]; isolecto-: G-BOIS [ G00332071 ]) .

Notes. – The lectotype at W has the collection number as Kotschy 747, but all other information on its label are basically identical to that of the G-BOIS isolectotype except the missing number and date and the original naming of the plant as “ Draba gigas Stur”.

At the end of the protologue, Boissier wrote “Drabo gigas Stur mss. in herb. Imp. Vindob!” This clearly means that he based his species description on the sheet at W. Furthermore, the sheet at W is a mixed collection involving a tiny fruiting plant of Erysimum sp. , a sterile portion of cushion, and much larger one of which the fruits were taken, except one left on the sheet which confirms the generic identity. Boissier did not annotate the W sheet, though based on the phrase above, he examined it and from which he most likely took the plant in G-BOIS and wrote its label. Therefore, the name needed lectotypification.
