Bauer, Norbert: Open sandy grasslands of the Bakony region

their (partly) phytogeographical importance in the Pannonian region. Here, Silene conica L., Plantago arenaria W. et K., Corispermum nitidum Kit. can be mentioned on more disturbed patches. During sampling the majority of these plants were proved to occur rarely and locally (appearing only in some parts of the region) on the sandy areas. The local appearance of Scabiosa canescens W. et K., in the grasslands along the railway embankment of Tilos-fenyő and Hangos-Fenyves (Bakonyszentlászló) is also important. The observation of Epipactis atrorubens Hoffm. ex Bess. (Bakonyszentlászló: Tilos-fenyő) also belongs to those absent in the coenological samples. Pulsatilla pratensis (L.) Mill, subsp. nigricans (Störck) Zamels, Chamaecytisus austriacus (L.) Link, Seseli osseum Cr., Silene otites (L.) Wib., Chrysopogon gryllus (Torn.) Trim, and Stipa pennata - dominant on closer sandy grasslands - is typical among the forest steppe species not connected to sand bedrock. The samples (FvS group) characterised by the dominance of Stipa pennata are slightly separated from the other Festucetum vaginatae samples (Fig. Fig. 2. Principal coordinates analysis (PCoA) of the samples (based on AD values). (Key to signs: crossed circle = samples of Fv group; empty circle = samples of FvS group; cross = samples of Br group; rhombus = samples of FvC group; full square = samples of Cc group; empty square = samples of CcK group).
