Penksza, Károly: Flora of the Fehér-szirt and its surroundings near Kesztölc, Hungary

gifolia W. et K., Kesztöíc in connection with the range of oak forests and Csaba (by its recent name Piliscsaba) in the enumeration of plant species of sandy habitats. FEICHTINGER (1864) enumerated 61 species according to their localities near Kesztöíc (Kétágú-hegy, foot of Kétágú-hegy, sand dunes, Fehérkő). The species number is 115 in the flora of Esztergom county (FEICHTINGER 1899). Most of these species are characteristic of forests, shrub-forests or rocky grasslands. However, Hypericum tetrapterum Fr., Triglochin maritimum L. and Gentiana austriaca A. et J. Kern, indicate wetlands. Five species are published by JÁVORKA (1904) from the Kesztöíc region: Alisma graminifolium Ehrh., Anemone nigricans (Stork.) Fritsch., Linum nudifolium Wierzb., Laserpitium Pruthenium L., Pharbitis purpurea Aschers. CSAPODY (1935,1939) reported two species from the vicinity of Esztergom {Adonisflammea Jacq., Arenaria graminifolia Schrad.). BOROS (1946) visited the Kétágú-hegy three times and the Fehér-szirt twice. He mostly reported bryophytes: Eurhynchium striatum (Hedw.) Schimp., Grimmia anodon B. S. G., Grimmia pulvinata (Hedw.) Sm. var. africana (Hedw.) Hook., Grimmia tergestina Tomm. var. tergestinoides (Culm.) Amann, Mannia fragrans (Balbis) Frey et Clark and Tortula intermedia (Brid.) De Not. The occurring vascular plants were the following: Herniaria incana Lam., Lactuca perennis L., Sempervivum schlechani Schott and Stipa pulcherrima C. Koch. New data were not recorded in BOROS (1953). Alkanna tinctoria (L.) Tausch, can be found in one of the relevés made by BORHIDI (1956). Detailed species list (155 taxa) on the marshlands is published by PENKSZA (1991). Some floristic data on the Fehér cliff are provided by PENKSZA (1992a). BOROS (1925, 1953) as well as BORHIDI (1956) reports on the occurrence of Thymus serpyllum L. RESULTS AND DISCUSSION Since 1990, 590 species have been recorded (see the check-list), of which 74 species were also found by FEICHTINGER (1899). The present list contains one unique species: Tragopogonfloccosus W. et K. Protected species of the area are the following: Adonis vernalis L., Cephalanthera damasonium (Mill.) Druce, Dactylorhiza incarnata (L.) Sou, Epipactis helleborine Crantz, Epipactis palustris (L.) Crantz, Festuca pollens Host, Fumana procumbens (Dun.) Gren. et Godr., Helleborus purpurascens W. et K., Iris graminea L., Iris humilis Georgi, Iris pumila L., Iris variegata L., Jovibarba hirta (Jusl.) Opiz, Lilium martagon L., Neottia nidus-avis (L.) Rich., Orchis mili-
