Flora of the Xingo region, Alagoas-Sergipe: Portulacaceae sensu lato

Abstract

Portulacaceae Juss. Includes herbaceous to subshrub plants, presenting fleshy leaves, alternate, sub-opposite to opposite, bisexual flowers, actinomorphic, with or without bracts, and fruit usually in capsule with longitudinal or transverse dehiscence. This paper deals with the floristic-taxonomic study of Portulacaceae in the Xingo region, in the states of Alagoas and Sergipe (Northeastern Brazil). We recorded 2 genera and 6 species: Portulaca L., with 4 species (P. elatior Mart. ex Rohrb., P. halimoides L., P. mucronata Link, and P. oleracea L.) and Talinum Adans., with 2 species (T. paniculatum (Jacq.) Gaertn. and T. triangulare (Jacq.) Willd.). We present descriptions, illustrations, and keys for separation of genera and species, besides distribution and habitat data on the species found in the area.
