  The authors report on the occurrence, distribution and invasion potential of Rubus armeniacus, a bramble species of Caucasian origin, in Hungary. The first verified records of the species are from the 1990s. It has established strong populations in ruderal habitats mainly around Budapest and some other cities, whereas its competiveness is rather weak in closed non-lowland forests rich in native bramble species. In terms of conservation, it constitutes a real threat to the vegetation of Pannonian sandy habitats. The results of this study also emphasize the importance of recognising "nonnative cryptic species" for ecology and conservation biology.

  Based on a substantial field-work and herbarium revision carried out between 2007 and 2014, the authors present the taxonomical evaluation of recently known representatives of Rubus L. ser. Micantes Sudre in Hungary, providing the first grid-based distribution maps and an identification key of four species of the section (Rubus balatonicus Borbás, R. clusii Borbás, R. styriacus Halácsy, R. tabanimontanus Figert) for Hungary.
