This study reports the location and presents a characteristic of a new alien species in the fl ora of Poland, i.e. Phytolacca acinosa Roxb. The position of Ph. acinosa is found in the Małopolska province, on the outskirts of the city of Tarnów. It is located at the edge of bushes, at a road leading through the area of settlement tanks and solid sludge dumps of a chemical plant Zakłady Azotowe S.A. in Tarnów-Mościce. Phytolacca acinosa plants are accompanied by species characteristic of nitrophilous ecotone forest edge communities and ruderal species.

CHARACTERISTICS OF THE POSITION The position of Ph. acinosa is located in Klikowa (ATPOL square EF ), in the north- -western district of the city of Tarnów in the Małopolska province (Fig. ). Geobotanically the analysed area belongs to the Baltic Division, the Subdivision of the Piedmont Basin Belt, the Sandomierz Basin Region, the Radomyski District (the inter- fl uve of the Dunajec and Wisłoka) (SZATA ROŚLINNA POLSKI ). In the physico-geographical regionaliza- tion of Poland (KONDRACKI ), this area belongs to the Carpathian Megaregion, the Western Carpathian Province with the Pod- karpacie Region (the Western Carpathians), the Northern Podkarpacie Sub-province, the FIG.

Leaf stalks range from . to cm in length, leaf base is wedge-shaped, the apex of the leaf blade is sharp or pointed. Numerous, densely clustered fl owers form a cy- lindrical raceme of - cm in length, which grows sympodially and is erect not only during fl ower- ing, but also during fruiting. Flowers are radial, bi- sexual, of approx. mm in diameter, growing from axils on peduncles - () mm long. The simple perianth (not diff erentiated into the calyx and the corolla) is composed of fi ve non-connate leafl ets, in- itially white in colour, later changing into green to become purple-red during fruit ripening (Phot. ). Leafl ets of the perianth are elliptical to egg-shaped or slightly elongated, - mm in length and mm in width. After pollination of fl owers they do not drop, but tilt backwards.
