The present study is focused on a volcanic mountain area of Maramures (Gutai Mountains) with specific vegetation that requires identification and analysis. The flora of these meadows has a natural character. The phytosociological study was performed and there was found vegetal associations belonging to classes Nardo - Callunetea Prsg. 1949, Molinio - Arrhenatheretea R. Tx. 1937 and Vaccinio-Piceetea Br.-Bl. in Br.-Bl. et al. 1939. The revealing species of the associations indicate a relatively poor floristic composition; great coverage has Nardus stricta, mainly due to acid substrate and to the bryophytes layer developed. Each vegetal association is described by analysis of the bioforms, of the floristic elements, geoelements, ecological indices and economic value. In all the vegetal associations hemicryptophytes exceeds other categories of bioforms, and considering the geoelements, the greatest rate is held by the Eurasian elements. From the point of view of the ecological character prevails mesophilic plants, micro-mesotherms and euritherms, euriionics and acidophilus. Meadows have a very low nutritive value and a low productivity, especially because of excessive grazing. Mosaic distribution of phytocoenosis is due to the uneven distribution of the climatic factors depending on the exhibition and on the degree of slope inclination.
