“…Rudolf Hoerold (1882Hoerold ( -1945, the one-time Director-General of Sanssouci near Berlin, was a German monographer of the tribe Thibaudieae, of whom Smith said (along with Hemsley) that his was the only comprehensive, if somewhat limited, work available to him. This was due to the fact that Hoerold was only working on specimens from one herbarium when conducting his studies in the early 1900s (Smith, 1932;Smith, 1996). He mentions some 53 species of Cavendishia with 22 of these being new in 1909 (Hoerold, 1909).…”
