Typus-Material imHieracium-Herbar von Hans Schack

Ferdinand Tessendorff (1879–1924) and his Hieracium collection

“…In the backlog of the Botanical Museum Berlin, the first author recently located several bundles containing 565 Hieracium specimens collected by Ferdinand Tessendorff between 1902 and 1922, all revised by the monographer of the genus, Karl Hermann Zahn. Like the important Hieracium herbaria of Karl Touton (Vogt 1998), Hans Schack (Vogt 1999;Vogt & Schuhwerk 2000& 2001, Joseph Bornmüller and August Schlickum (Vogt 2001), this collection of Tessendorff was not incorporated into the general herbarium before 1 March 1943, and for that reason it escaped the disastrous fire of the Botanical Museum Berlin. All these collections were relocated to a safe place in the Harz mountains, where they survived the Second World War unscathed.…”
