Kivonat:

Geum rivale L. new for the Hungarian Flora was discovered in Aegopodio-Alnetum community of Szuha-streamlet N of Szuhafő village, NE-Hungary, near the Slovakian border. Coenosystematical affinity of the species in the Carpathian Basin (with regard to the latest Slovakian and Romanian literature) is discussed. Considering relation between Aegopodio-Alnetum and Alnetum incanae communities, on the base of Hungarian data, contrary to Jurko (1961) Geranium phaeum, Geum rivale, Oxalis acetosella, Petasites hybridus, Senecio fuchsii can not be considered as differential species of Alnetum incanae, while some characteristic shrubs (e.g. Acer tataricum, Malus sylvestris) seem to prefer Aegopodio-Alnetum (see Kárpáti–Kárpáti–Jurko 1963; Nagy 1997; Vojtkó 1995 and our relevé).

Some coexisting characteristic species of the Aegopodio-Alnetum community of Szuha-streamlet (e.g. Anemone nemorosa, Cardamine amara, Carex elongata, Cirsium oleraceum, C. palustre, Dryopteris carthusiana, D. dilatata and especially Oenanthe banatica) are also mentioned.
