Lectotypus (designated here): IRAN: “Ad radices m. Demawend pr. p. Lar.”, 19.VI.1843, Kotschy 333 (G-BOIS [G00332600]; isolecto-: BM [BM000582563], E [E00386030, E00386031], FI [FI 005706], G [G00371783, G00371784], GOET [GOET002619], K [K000642860], KW [KW000127956], LE [LE00012915, LE00012916], MO [MO1930850], P [P00580385, P00741455, P00741456, P00741457, P00741458, P004745146, P05384224], W [W0050808, W0075582], WAG [WAG0000827]) .

Notes. – The sheet in Bunge’s herbarium P00741456 was annotated on a small piece of paper by Boissier as “ Isatis kotschyi B.”, and that annotation justifies lectotypifying the name.

Label of one duplicate [P05384224] has exactly the same information as that of the type except for a collection number as Kotschy 333a instead of 333, and it is recognized here as an isolectotype.
