Penksza, Károly: Flora of the Őr-hegy (Gerecse Mts, Hungary)
The northern border of the investigated area is the Bajna-Epöl highway, in other directions it extends to the arable lands (Fig. 1). The regular field-work started in 1984. Comparative specimens of the herbarium of the Botanical Department of the Hungarian Natural History Museum (BP) were used for the identification of certain species. The species names are followed by references if they were found formerly by other authors. Natural conservation ranks were established according to SIMON (1992). For identification of the Rosa species FACSAR' s monograph (1993) was used. Nomenclature principally follows SIMON's (1992) for the vascular plants and PRlSZTER's (1980) for some author names, while ORBÁN and VAJDA (1983) was used for the mosses. Fig. 2.
