|Hieracium joannei Szeląg|
Hieracium joannei, a new, apomictic species in H. sect. Cernua is described from the Şureanu Mountains, Southern Carpathians, Romania, and illustrated with photos of the holotype and living plants in the locus classicus. Hieracium zanogae (= H. tubulare), previously considered to be endemic to the Retezat Mountains, has been found in the Parâng Mountains. This is the easternmost occurrence of the species, disjoined ca 50 km from the nearest localities in the Retezat Mountains. A key for the species of H. sect. Cernua in Romania is provided.

Hieracium joannei Szeląg, sp. nov.
Type:— Romania. Southern Carpathians, Şureanu Mountains, SE slope of Muntele Pravăţ ridge. ...
Distribution and habitats:— Endemic to the Şureanu Mountains, Southern Carpathians, known only from the type gathering; nevertheless its occurrence in the adjacent Parâng Mountains has been expected. The population of Hieracium joannei was composed of a few hundred flowering plants growing on a south-facing slope covered by grassy vegetation and Brucenthalia spiculifolia, and on siliceous rocks and crevices along the Picea abies forest margin.
Mode of reproduction:— Agamospermous.
Etymology:—The new species is named in honour of Dr. hab. Jan (Latin: Joannes) Bodziarczyk, University of Agriculture in Cracow, who accompanied me on a field trip to Romania in July 2014.
