Rosa × braunii, a new rose hybrid in Slovakia

Abstract

A new rose hybrid was found in Slovakia, Malé Karpaty Mts, close to the Plavecky Peter on the hill Ježovka. This rose taxon called Rosa × braunii was described by Jenő B. Keller from the Bruck an der Leitha (Austro-Hungarian Empire) in 1882. It is a hybrid of R. tomentosa Sm. and R. spinosissima L. Its morphology, diagnostic features, chorology and conservational status are discussed. Legal protection of this taxon is highly recommended, because this is its second population in the world, the only currently known locality, and it is a unique taxon, not an introgressive hybrid
