Treatment

Pilosella sericochrota (Zahn) Szeląg & Vladimirov , stat. et comb. nov.

Basionym:― Hieracium pseudopilosella subsp. sericochrotum Zahn View in CoL in Ascherson & Graebner (1922: 60).

Type:― BULGARIA. Plantae Rumeliae orientalis, exssicatae curante Dre de Degen. In graminosis regionis alpinis vallis Maritzae superioris sub monte Musala, Rhodopes centralis, 30.07.1892, J. Wagner (lectotype BRNM 10983/36, designated here).

Distribution and habitats: ― Pilosella sericochrota is a high-mountain species and prefers habitats on siliceous (mainly granite) bedrock, above 2000 m a.s.l., and is frequent in the Pirin Mountains and Rila Mountains. It is likely that P. sericochrota is endemic to Bulgaria because its occurrence in thermophilous vegetation on Mt. Chortiatis (Χορτιάτης) (only 1201 m a.s.l.) near Thessaloniki in Greece as reported by Zahn (1923) seems very unlikely. Furthermore, this locality is attributed to Imre Friváldszky, an eminent Hungarian entomologist, who organized the expeditions to the Balkan Peninsula but did not participate in these expeditions himself (cf. Szeląg & Somlyay 2009).
