Abstract

CERVI, Armando Carlos; BONA, Cleusa; MOCO, Maria Cecília de Chiara  and  VON LINSINGEN, Leonardo. Aquatic macrophytes at General Carneiro, Parana State, Brazil. Biota Neotrop. [online]. 2009, vol.9, n.3, pp.215-222. ISSN 1676-0611.  http://dx.doi.org/10.1590/S1676-06032009000300022.

A floristic study of macrophyte communities was conducted at General Carneiro township, situated in Southern Parana State, among 26º 19' 37"/ 26º 26' 40" S and 51º 26' 51"/ 51º 19' 14" W. Samples were collected at São Pedro, São Pedro II, Santa Cândida and Lageado Grande farms, between the rivers São Pedro, São João, São Manoel, Iratim, Lajeado Grande and Neno, in order to study the flora of the rivers and ponds in this region. Macrophyte samples were randomly collected between 2004 and 2006 and registered in the UPCB and MBM herbaria. A total of 45 families was found, 42 of them being angiosperms, 70 genera and 117 species. The aquatic environments are floristicaly characterized by Cyperaceae, represented by 22 taxa, what means approximately 21% of all the encountered taxa, followed by Poaceae (8), Asteraceae (7) and Polygonaceae (6). Among the registered species we can highlight the first record in this state of Lilaeopsis minor Prez-Mor, Apiaceae.

Keywords : hydrophytes; aquatic plants; floristic survey; Cyperaceae; Poaceae.
