Hesperis thyrsoidea Boiss., Fl. Orient. 1: 234. 1867. Type: “Hab. in rupestribus faucium prope Baibout Armeniae (Bourg!), in monte Berytdagh Cataoniae (Haussk!)”. Lectotypus (designated here): TURKEY: “Taurus Cataonicus. Berytdagh in ipso Popul.”, 6000' [1830 m], 10.VIII.1865, Haussknecht s.n. (G-BOIS [G00332222]; isolecto-: JE [JE00002541]). Syntypus: TURKEY: “Dans les ravins près Baibout”, 2.VII.1862, Bourgeau 132 (G-BOIS [G00791931], P [P00234985, P02272559, P04661335]). Notes. – Boissier in Flora Orientalis based the species description only on the G-BOIS and JE duplicates of both syntypes above. The fragmentary W0032956 specimen has a preprinted label with Haussknecht’s handwritten information “In dumetis popul. Bewul. m. Berytdagh Cataoniae. alt. 7000 ped. die 7.8.1865 ” that differs in the elevation and day of collection and, therefore, is not considered here as part of the type collection. Based on these facts, the listing of DVOŘÁK (1968b: 273) of that sheets as part of the type collection is erroneous. The three Bourgeau syntypes at P do not have a collection number and the G-BOIS syntype is a collection folder of two sheets. CULLEN (1965: 455) placed H. thyrsoidea as a synonym of H. cappadocica E. Fourn. (Bull. Soc. Bot. France 13: 351. 1868) because he interpreted the publication date of the latter name as 1866 instead of 1868. For exact publication dates of that journal, see LEUSSINK (1985).
