Nomenclatural notes on Euphrasia coerulea Tausch (Orobanchaceae)

Euphrasia coerulea Tausch (1834a: 445) was described based on specimens from the Isergebirge (now Jizerské hory Mountains in the Czech Republic) in the Western Sudetes. The species occurs in Central Europe, in the Hercynian and Carpathian provinces (Smejkal 1963: distribution map). The name E. coerulea was validated by Tausch (1834a: 445) by means of the shortest possible diagnosis: ‘ganz blaue Blumen’ as opposed to the white flowers characterizing E. officinalis var. alpestris Günther et al. (1824: 164) with which Tausch compared his new species. Junger and Engler (Junger 1867), followed by Kerner (1881: 44), Wettstein (1894: 95, 1896: 115), and Smejkal (1963: 28), considered E. coerulea as a nomen nudum, but acknowledged that it was published in Synopsis Florae Germanicae et Helveticae (Koch 1837: 546). They illegitimately renamed the species E. uechtritziana Junger & Engler (Junger 1867: 141), with “E. coerulea Tausch (pl. sel. Boh.) Koch’s Syn. etc. (1837)” cited in synonymy

Hieracia balcanica VIII. Hieracium nigrescens subsp. brachytrichellum (Asteraceae), a new taxon in the Balkan flora

Hieracium nigrescens subsp. brachytrichellum Zahn, known to date only from the Southern Carpathians, was discovered in the Vranica Mountains in Bosnia. This is the first station of H. nigrescens s.l., an arctic-alpine species of H. sect. Alpina (Griseb.) Gremli, on the Balkan Peninsula. A map of general distribution of H. nigrescens s.l. and illustration of the specimens collected in Bosnia are given. The likely origin of the Balkan population is briefly discussed

Typification of the Hieracium (Asteraceae) names described by J. Freyn from Turkey

Nine names in Hieracium s.l. by Josef Freyn and three names by Karl H. Zahn from Turkey are lectotypified from among specimens stored at BRNM. For another two species the holotypes were found in BRNM and WRSL. The authorship of the name H. leucothecum is ‘R. Uechtr.’ under Art. 46.2 of the Code. All discussed taxa are illustrated by photos of original specimens

Taxonomic and nomenclatural notes on Hieracium tomosense (Asteraceae), a neglected Carpathian endemic

Hieracium tomosense Simk., a mountain forest species known to date only from the Piatra Mare Mts in the Southern Carpathians, Romania, has been found in other parts of the Southern and Eastern Carpathians. This hybridogenous species of the morphological formula H. transylvanicum > H. murorum was incorrectly included by Zahn and Nyárády into H. transylvanicum Heuff. as a variety, thus sending H. tomosense into oblivion. A distribution map of H. tomosense is presented and its relation to H. praecurrens is discussed. The name H. tomosense is lectotypified by a specimen stored at the Hungarian Natural History Museum in Budapest (BP)

Hieracium sudetotubulosum (Asteraceae), a new name for the illegitimate H. tubulosum (Tausch) Tausch

Hieracium alpinum var. tubulosum Tausch (1828: 63) was raised to species rank as H. tubulosum (Tausch) Tausch (1837: 68), an illegitimate homonym of H. tubulosum Lamarck (1786: 367). The latter is a different, unrelated species pertaining to the H. intybaceum aggregate and described from the Alps, whereas Tausch’s taxon is endemic to the Sudetes and belongs to the H. alpinum aggregate (Chrtek, 1997). Hieracium tubulosum (Tausch) Tausch differs from other central European species of the H. alpinum aggregate by having tubular florets, so that the replacement name proposed below is etymologically appropriate

Typification of Chrysanthemum zawadzkii (Asteraceae)

The name Chrysanthemum zawadzkii Herbich is typified by the illustration published in the protologue, and epitypified by the specimen collected in 1832 by F. Herbich in the Pieniny Mts, Western Carpathians, and stored at the herbarium of the Ivan Franko National University of Lviv (LW). The original spelling of the species epithet is clarified

Hieracium sudetotubulosum (Asteraceae) rediscovered outside the Karkonosze Mts

Hieracium sudetotubulosum Szeląg [= H. tubulosum (Tausch) Tausch, nom. illeg.], considered to be endemic to the Karkonosze/Krkonoše Mts, has been found on Mt. Szczeliniec Wielki in the Góry Stołowe Mts, SW Poland. This is the easternmost occurrence of the species, disjoined from its continuous geographical range in the Karkonosze Mts by ca 50 km. The occurrence of H. sudetotubulosum on Mt. Szczeliniec Wielki was published by Zahn in 1938 but it was overlooked in the modern literature
