Hieracium caesium f. aphyllopodum Zahn in Bornmüller (1943: 266).

Ind. loc.: “In consortio subspecie typicae” [= Villach, in den Auenwäldern am Ufer der Gail, sehr zahlreich am Weg von Warmbad-Villach nach Müll[n]ern, ca. 500 m.]

Lectotype (designated here by Gottschlich): — AUSTRIA. Carinthia: Villach, bei Müllnern, Wäldchen am Weg nach Warmbad, 500 m, 19 July 1938, J. Bornmüller (B barcode B 10 0453999!; isolectotype: B barcode B 10 0454000!).—Current name: Hieracium caesium subsp. brennerianum ( Zahn 1901: 1817) Gottschlich (2007: 45) .

Remarks: —Label with handwritten determination and diagnosis of Zahn. The only diagnostic character given by Zahn (“foliis radicalibus nullis, ergo caulinis ad 10”), relies on phenotypic variation due to overwhelming with fine rock debris. For this reason the form aphyllopodum should be considered as synonym of Hieracium caesium subsp. brennerianum (Zahn) Gottschl. , the current name of Zahn’s subsp. sarntheinianum .

Hieracium canescens subsp. chaunotrichum Bornm. & Zahn in Zahn (1935: 755), nom. inval.: sine descr./diagn. Lat. (ICN Art. 39.1, Turland et al. 2018).

Ind. loc.: “Riesengebirge: Kirche Wang Ɨ Schlingelbaude, 1000 m!”

Relevant specimen:— POLAND. Lower Silesia: Riesengeb [irge] [Karkonosze Mts.], zwischen Wang u. Schlingelbaude , Nadelwald , 8 August 1930, J. Bornmüller (B barcode B 10 1154503!) .

Remarks: — Hieracium canescens Link (1822: 288) is one of the most critical species within the genus and needs a thorough revision. Bornmüller´s specimen may belong to Hieracium levicaule Jordan (1848: 23).
