Floristic composition of a Subtropical bog, Eastern Plateau from southern Brazil

This is a comprehensive list of plants and fungi from a bog in the Southern Brazilian Plateau, which may be used as a reference for subtropical marsh flora investigations. The very well preserved bog named Banhado Amarelo (29°19' S, 50°08' W) is located on the eastern Plateau of Rio Grande do Sul, the southernmost state of Brazil. A total of 262 specific and infra-specific taxa were listed, including six macroscopic fungi, 10 lichens, 21 mat forming algae, 57 bryophytes, 12 pteridophytes, two gymnosperms and 154 angiosperms. For every taxon the mode of occurrence in the bog was indicated. The frequency of distinct taxonomic groups among themselves was determined and a general description of the flora of the main bog environments is presented. The number of taxa found in the bog was compared to those obtained in other surveys of bogs of the eastern Plateau from Rio Grande do Sul
