Abstract

SOUZA, Tainã de; TREVISAN, Rafael  and  SILVA, Shirley Martins. Synopsis of Poaceae in the grassland formations of the Parque Estadual do Guartelá, Paraná State, Brazil. Hoehnea [online]. 2018, vol.45, n.2, pp.202-224. ISSN 2236-8906.  http://dx.doi.org/10.1590/2236-8906-36/2017.

Poaceae is a cosmopolitan family that includes species found in both forest and grassland formations. The objective of this study was to carry out the first floristic survey of Poaceae in the Parque Estadual do Guartelá (PEG), one of the last remnants of native grassland vegetation in the State of Paraná, Brazil, and provide resources to assist the identification of genera and species. The survey was conducted based on field collections and searches in the Species Link online database. In the PEG, Poaceae is represented by 29 genera and 54 species, being Paspalum L. (eight spp.), Andropogon L. (five spp.) and Eragrostis Wolf (four spp.) the richest genera. The number of species in the PEG was incremented by 29 new records. In addition, five species were classified as exotic, five as endemic to Brazil, and two were considered least concern in relation to their conservation. We also present information regarding the distribution, habitat and conservation status for each species.

Keywords : Campos Gerais; floristic; Gramineae; grasses; grassland formations.
