Bieberstein ( lectotype LE 01080952, designated by Krytzka et al. (1999 : 611)). Distribution. Europe: France, Italy, Balkans, Greece, Crimea ( Cristofolini 1991 ); Asia: Russian Western Caucasus. Notes on taxonomy and distribution. Cytisus polytrichus sharply differs from C. hirsutus in its creeping stems, small leaves and constantly axillar flowers ( Cristofolini 1991 ). Plants of this species have been known from the Western Caucasus under a wrong name, C. wulffii auct. ( Kreczetowicz 1940 ; Grossheim 1952 ). The latter species is endemic to the Crimea and differs from C. polytrichus in appressed (vs. strictly patent) hairs on its leaves and calyces ( Sennikov and Tikhomirov 2024a ). Notes on nomenclature. Krytzka et al. (1999) designated the only suitable specimen at LE as lectotype, following the unpublished annotation by N.N. Tzvelev.
