Actual geographic distribution of Orobanche pallidiflora Wimm. & Grab. in Poland is presented. All the 40 present-day Polish stations (including new and unpublished ones) of this species are mapped, as well as 19 historic localities from literature and ATPOL data base. The sites have been ordered and numbered according to ATPOL 10 km x 10 km grid and described by its geographical coordinates and references. Brief descriptions of general distribution and habitat of this rare and endangered species is also given. Key words: distribution, Orobanchaceae, Orobanche pallidiflora, Poland, rare species. Słowa kluczowe: gatunki rzadkie, Orobanchaceae, Orobanche pallidiflora, Polska, rozmieszczenie. INTRODUCTION Orobanche pallidiflora Wimm. & Grab. is a species known from only a few sites in Poland (Mądalski 1967, Zarzycki et al. 2002). It has been assigned to a group of plant species regarded as endangered in Western Pomerania (Ginące 1995) and Lower Silesia (Kącki et al. 2003), critically endangered in Gdańsk Pomerania (Markowski and Buliński 2004) and rare in Poland (Zarzycki and Szeląg 1992, 2006). Since recently, the species has been under legal protection (Directive of Minister of the Environment of 9 July 2004, DzU No. 168, Item 1764). The species has been placed on the Red Lists in the German regions of Brandenburg (Rote 1992) and Mecklenburg (Benkert and Klemm 1990). Orobanche pallidiflora represents the family Orobanchaceae which encompasses exclusively the forms which parasitise, by means of suckers, other vascular plants. Its hosts include various Asteraceae species, primarily those belonging to the genus Cirsium and Carduus, and more seldom species of the genus Knautia and Scabiosa (Mądalski 1967, Webb 1972, Gilli 1975, Zázvorka 2000). The present distribution of Orobanche pallidiflora sites in Poland is poorly known. The map, plotted on the basis of the ATPOL data ( Distribution Atlas of Vascular Plants in Poland ), shows a single extant site only. The remaining 24 sites are regarded as extinct, unconfirmed, or doubtful (Atlas 2001). However, the species has been recently reported from new, earlier unknown sites. They are clustered in the North-West (Bacieczko 1984, 1991, 1995, 2002, Ziarnek 2002, Myśliwy 2003, Bacieczko and Myśliwy 2005), North-East (Łachacz 2002), and South of Poland (Kwiatkowski 2001, 2005). Under such circumstances, a new description of the species point-wise distribution in Poland is necessary and is provided by this paper.

6 W. Bacieczko and M. Myśliwy MATERIAL AND METHODS The new map of Orobanche pallidiflora distribution in Poland is based on data drawn from floristic literature and ATPOL as well as information yielded by the authors own research and other unpublished sources. Herbal materials cited in the paper was checked by dr Zbigniew Szeląg. Correct determination of the species from present-day sites cited in the literature was also confirmed by the specialists in Poland and the Czech Republic (personal information from authors). The map was plotted point by point to mark the 40 extant and 19 historic sites of the species (Fig. 1). The sites have been ordered and numbered, from North to South, according to the ATPOL 10x10 km grid (Zając 1978). Each site is described by its geographical coordinates and reference (author s name and year of publication in the case of published evidence).

GENERAL DISTRIBUTION According to Pawłowska (1972), Orobanche pallidiflora is, in the Polish flora, a representative of the Euro-Siberian sub-element. Rothmaler (1988) assigned the species to the

The distrubution of Orobanche pallidiflora Wimm. & Grab... 7 European-West Siberian distributional group. According to the nomenclature of Meusel et al. (1978), Orobanche pallidiflora is the Euro-West Siberian element. The distributional range of Orobanche pallidiflora covers a small continuous part and numerous separate, island-like sites. The continuous part encompasses areas east of the Rhone in France and north of the Po in Italy as well as Switzerland, the southern part of Germany, a major part of Austria (south of the Danube), the south-eastern part of Slovenia, a northern fragment of Croatia, and the western flank of Hungary. The island-like sites are concentrated in Central Europe (Germany, Poland, Bohemia and Slovakia) and South- Eastern Europe (from Greece to Hungary and Romania). The westernmost sites were reported from south-eastern Spain, southern France, and the central part of Great Britain. The northern border of the range is marked by a line connecting Denmark, southern Sweden, Latvia, and Estonia. In the eastern part of Europe, the range extends to the Urals, Don, and Caucasus. In Asia, Orobanche pallidiflora has been reported from the vicinity of Novokuznetsk. The southernmost sites are those found on the northern coast of Africa (Meusell et al. 1978). HABITAT According to the monograph by Mądalski (1967), Orobanche pallidiflora has been recorded in meadows, forest clearings, and scrubs. The recently found sites expand slightly the range of the species habitats. In the Western Sudety Mountains, the species inhabits mainly low calcareous hills with abandoned quarries or gravel pits and grows in xerothermic grasslands, more seldom on wet meadows or in mountain riparian forests (Kwiatkowski 2001). In the Romincka Forest, the species has been recorded in waterhead peatbogs (Łachacz 2002). In the western part of the country, Orobanche pallidiflora is encountered mainly on moist or wet meadows, on the shores of fish ponds or other small water bodies, and more seldom on fallow land, near roads, in balks and scrub (Bacieczko and Myśliwy 2005), and sporadically on plantations of the conifers and black currant (Grzejszczak, personal communication).

CONCLUSIONS Gilli (1975) divided Orobanche pallidiflora into two sub-species: (i) ssp. pallidiflora, with corolla white to yellowish, somewhat maroon near the margin, sparsely glandular pubescent, and with pubescent or naked, sparsely glandular stamens; (ii) ssp. reticulata, with corolla usually purple- or intensively purple pigmented, dark-veined, yellow at the base only, relatively densely glandular pubescent; stamens glandular pubescent below the anthers. While the first taxon occurs mainly on lowlands, the other is rarer and typical of mountainous areas. Present-day sites shown on the map support the first of the two sub-species. Recent floristic studies have greatly expanded the list of Orobanche pallidiflora sites known from Poland. Occasionally, a mass occurrence of the species is observed. Detailed ecological and habitat-oriented studies are needed to propose appropriate methods of the species conservation. In addition, it would be desirable to monitor selected population on a permanent basis. Acknowledgements.
