Hieracium guentheri-beckii subsp. portentosum Hayek & Zahn in Zahn (1921: 580).

Ind. loc.: “Nordost-Albanien: Felsen der Gipfelregion des Paštrik (Doerfler, Cerny)!”

Lectotype (designated here by Gottschlich): — ALBANIA. Kukës: Flora v. N. Albanien, Distr. Hasi, Felsen der Gipfelregion des Paštrik, 1700 m, 27 July 1918, I. Dörfler (Reisen in Nord-Albanien 1916 und 1918, no. 877a) ( B barcode B 10 0001200!; isolectotypes: B barcode B 10 0420876!, BRNU barcode BRNU 34032!).

Remarks: —We selected here as lectotype the specimen from D i rfler´s personal herbarium – mentioned in Vogt et al. (2018: 82) as syntype – because it bears the handwritten determination by Zahn and contains three well developed plants instead of one reduced plant on the specimen in the Bornmüller herbarium. The isolectotype in B bears a preprinted label from Bornmüller with the (erroneous?) elevation “ 1800 m ”.
