Abstract

We present in this paper the phytosociological analysis of 50 samples of peat deficient alder swamps (Angelico sylvestri-Alnetum glutinosae) found in the Zákány Hills along the Drava river in southwestern Hungary. Most of these swamps are found on nutrient-rich alluvial soil along the Visszafolyó stream. The species composition of them does not show signs of sub-Mediterranean and Illyrian influences, which generally are characteristic of the Zákány Hills. Instead, it is characterized by the occurrence of a number of regional rarities, such as Alnus incana, Cardamine amara, Carex elongata, C. pseudocyperus, C. rostrata, C. strigosa, Doronicum austriacum, Dryopteris carthusiana, D. dilatata, D. expansa, Equisetum hyemale, Geranium palustre, Leucojum aestivum, Peucedanum palustre, Ranunculus lingua, Ribes rubrum, Rubus idaeus, Scilla drunensis, Thelypteris palustris, Veratrum album. The stands are somewhat related to alder gallery forests (Carici pendulae-Alnetum glutinosae), but are more closely related to typical alder swamps (Carici elongatae-Alnetum glutinosae). As an associastion, it is classified in the suballiance Scirpo sylvatici-Alnenion glutinosae Kevey 2008a.
