A FAMÍLIA POACEAE NA SERRA DE ITABAIANA, PARQUE NACIONAL SERRA DE ITABAIANA, SERGIPE-BRASIL

Abstract

This paper presents the results of a taxonomic study of the family Poaceae held in Parque Nacional Serra de Itabaiana, with the objective of contributing to the knowledge of species richest of the Park. The PARNA Serra de Itabaiana (10 45'15''S and 37 25'15''O) is located in the state of Sergipe and covers an area of 7966 ha which includes three units, the serra do Cajueiro, Comprida and de Itabaiana. Collections were made between April 2006 and April 2008 and deposited in UFP, ASE, MO, and RB. Information on distribution have been raised from herbaria, literature and databases available on the Internet. We identified 40 species in the PARNA classified into 19 genera, the richest of which is Paspalum L., with eight species. Five species had their distribution extended in this work. A key to identify the species is presented, as well as comments on distribution and ecology.
