Vogt, Robert & Gottschlich, Günter, 2022, Ferdinand Tessendorff (1879 - 1924) and his Hieracium collection, Willdenowia 52 (1), pp. 83-90 : 89

Hieracium murorum subsp. suevicola Zahn in Engler, Pflanzenr. 76(IV, 280): 306. 1921 (“ suevicolum ”). – Ind. loc.: “ Württemberg ( Hohenacker , Arznei-Pfl. n. 353)! Harz : zwischen Walkenried und Sachsa ( Zobel )! Berlin : Tegeler Forst ! Insel Rügen !”.

– Lectotype (designated here by Gottschlich): [ Germany]: Berlin – Tegeler Forst , 29 May 1920, F. Tessendorff ( B [ B 10 1154496 ]) [ Fig. 3 ]. – Current name: Hieracium murorum subsp. suevicola Zahn.

Remarks — The blank label (“Museum botanicum Berolinense. leg. F. Tessendorff”) bears the handwritten determination particulars of K. H. Zahn. Although it is usually appropriate to select a lectotype among specimens from an exsiccata series, here we selected Tessendorff’s specimen, because we never saw material collected by Hohenacker. Perhaps the indication of “Hohenacker, Arznei-Pfl., n. 353” made by Zahn refers to a specimen formerly at B and now destroyed.
