PENKSZA Department of Botany and Plant Physiology, Agricultural University H-2103 Gödöllő, Hungary Floristic data collected by the author since 1990 on the Fehér-szirt and its surroundings near Kesztöíc, Pilis Mts, Hungary are presented. The list of taxa consists of 593 species. Key words: floristics, check-list, Pilis Mts, Hungary INTRODUCTION Investigations on the flora and the vegetation of the Fehér-szirt and its surroundings near Kesztöíc have been carried out since 1990. Areas close to the natural state got priority during our work, however, abandoned vineyards were investigated as well. Arable lands were omitted. The flora of the Pilis Mts, especially its southern parts close to Budapest were studied by several notable botanists. The herbarium of Kitaibel already contains plants from the Pilis Mts (JÁVORKA 1926-1936). SADLER (1825, 1840) made detailed investigations in the region. KERNER (1857) gave an overview of the Pilis Mts, too. The studies of BORBÁS (1871, 1879) dealt with the parts of the mountains belonging to Pest county. Floristic data on the northern part of the Pilis Mts were published by FEICHTINGER (1864, 1899). Despite other floristic studies he enumerated the exact localities of each occurring. Authors publishing additional floristic records on the Pilis Mts are BOROS (1917, 1919, 1923, 1938, 1970), CSAPODY (1935, 1939), DOMOKOS (1939), FEKETE and JAKUCS (1957), GRÜNDL (1863), HORÁNSZKY (1957), JÁVORKA (1904,1915,1940) and LENGYEL (1906, 1909). However, few studies have exact reference on Kesztöíc or its close surroundings. Floristic data on the swamp meadows in the vicinity of Kesztöíc and on the Hosszú-rét between Piliscsaba and Piliscsaba-Jászfalu were published by PENKSZA (1991). The most important floristic data on the Fehér-szirt (PENKSZA 1992a) and the phytosociological characterization of the swamp meadows found here were reported by PENKSZA (1992&). The phytogeography of the Pilis Mts and its surroundings were described by BOROS (1953) and FEKETE (1988). BORHIDI (1956) studied the sandy vegeta-
