Hieracium dolopicum subsp. niphophorum Zahn (1921: 576) .

Ind. loc.: “ Mazedonien: Treska! Serbien: Berg Basara bei Pirot! Suha Planina bei Nisch! Felsen bei Ušica (Adamović!, Ilić!, Bornmüller!). Bulgarien: Trojan Balkan! Bosnien: Rogatica!, Staribrod! Hercegowina: Suha Gora! Albanien: Neresi!, Skala Bicajt!, Berg Tomor, Kalarryta, Syrakou (Baldacci III n. 172 pp., 210 pp.)!”

Syntypes:— SERBIA: Serbiae austr., Suha Planina, July 1887, G. Ilić ( B barcode B 10 1154371!); Prope Užica , in rupibus, July 1887, J. Bornmüller ( B barcode B 10 1154370!) ; SERBIA: Serbia austr.-occid., in rupestr. umbrosis supra Ušica , 23 August 1887, J. Bornmüller ( B barcode B 10 1154369!).—Current name: Hieracium bosniacum Freyn (1895: 508) .

Remarks: —The latter syntype bears two labels from Bornmüller with differing collection dates, 23 August 1887 and 24 August 1887, respectively. Zahn cited Hieracium bosniacum as synonym, so H. bosniacum subsp. niphophorum must be synonymized with the nominal subspecies. The treatment of H. bosniacum in Freyn (1895) includes some nomenclatural inconsistencies. As stated in the introduction, Josef Freyn wanted to list the taxa in the key without stating a definitive rank, although all are listed with the prefix “H.”. On p. 652/653 he presented a systematic treatment, in which he specified three main species, a lot of intermediate species and some subspecies. Hieracium bosniacum is listed there as intermediate species, however, in the enumeration of all taxa it is listed in the rank of subspecies.
