AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 105

Draba affghanica Boiss., Fl. Orient. Suppl.: 55. 1888.

Type: “Hab. in alpinis ad Schendtoi, Sikaram, etc. vallis Kuram Affghaniae (Aitch. 99! 112! 126!)”.

Lectotypus (first step designated by JAFRI, 1973: 134; second step designated here): PAKISTAN: “Affghania”, 12.VI.1880, Aitchison 99 ( G-BOIS [ G00330491 ]; isolecto-: GH [ GH00046951 ], K [ K000568096 ]) . Syntypi: PAKISTAN: “Affghania”, 10000'–14000' [3050–4270 m], 12.VII.1880, Aitchison 112 ( G-BOIS [ G00332438 ]) ; sine loco, 13.VI.1880, Aitchison 126 B ( G-BOIS [ G00332439 ], K [ K000568066 ], LE [ LE00012963 ]) .

Notes. – A second-step lectotypification is necessary to correct the lectotype from K to G-BOIS because Boissier never examined or annotated any of the duplicates at K.

The specimens at K sometimes include different collections of Aitchison or different numbers on the same sheet (e.g., [ K000568066 ]). However , all are from Afghanistan, and they lack data on collection dates or specific localities. Untangling the finer details of each these requires consulting the fieldbooks and travel itineraries of Aitchison, a task beyond the scope of this work, and that is why they are treated herein as syntypes .

What is most important for the lectotypification of the species name is Aitchison 9 9 because it was initially designated by JAFRI (1973: 134), and its single problem is resolved by taking the G-BOIS as the lectotype.
