Bauer, N., Lőkös, L.; Papp, B.: Distribution and habitats of Cardaminopsis petraea in Hungary

previously published floras of low and small island-like basalt monadnocks (see BORBÁS 1900, SOÓ 1930, JÁVORKA and Soó 1951, FEKETE 1964). The geomorphological (differently exposed, often vertical stone walls; alternation of debris slopes and crumbling, block disintegrating stone types) and microclimate features (strongly depending on the geomorphology) of the volcanic monadnocks made the remaining of Cardaminopsis petraea, Saxifragapaniculata, Aurinia saxatilis and other glacial and postglacial rocky relicts on the Transdanubian basalt hills [e.g. Dianthus plumarius subsp. lumnitzeri (Szent György Hill, leg. Zsák Z., 1920, publ. BAKSAY 1972), Hieracium wiesbaurianum (Badacsony, Borbás 1900, Szent György Hill, Bauer ined.)] possible. Because of their phytogeographical importance, the populations of Cardaminopsis petraea restricted to limited areas in Hungary would deserve greater attention of the nature conservation authorities. We are working on a proposal that will hopefully result in the declaration of the plants' remaining habitats strictly protected. * * * Acknowledgements - Our thanks are due to Lajos Balogh, István Isépy, Levente Nagy, Balázs Pintér, Gábor Sramkó and Tibor Szerdahelyi for helping in data collection in herbaria under their care, to Lajos Somlyay, Gábor Papp and Attila Szabó T. for helping in literature research, and to János Csiky for the thorough revision of the manuscript.
