Cyperaceae do rio Apodi-Mossoró, Estado do Rio Grande do Norte, Brasil

Abstract

-(Cyperaceae in the Apodi-Mossoró River, Rio Grande do Norte State, Brazil). The Apodi-Mossoró River, located in the Caatinga biome, has its course characterized by diverse landscape sand humid environments, as well as by many members of the family Cyperaceae. Studies on the flora of Cyperaceae are scarce in northeastern Brazil and nonexistent for Rio Grande do Norte State. Twenty-one botanical expeditions were undertaken in this area during the period from July 2007 to May 2008 on four main points in the municipalities of Felipe Guerra, Governador Dix-Sept Rosado, Luís Gomes, and Mossoró. Seven genera and twenty-five species of Cyperaceae were found in the Apodi-Mossoró River, twenty-one of which are new records for Rio Grande do Norte State.This figure more than doubled the number of species of the family known to occur in this Brazilian State. Botanical descriptions, taxonomic comments, identification keys, and illustrations are provided.

Integrative research identifies 71 new plant species records in the state of Rio Grande do Norte (Brazil) and enhances a small herbarium collection during a funding shortage

“…Groups that have been studied recently include Chamaecrista (Queiroz and Loiola 2009), Turneraceae (Rocha et al 2012), Paspalum (Oliveira et al 2013a), Leguminosae-Papilionoideae (São-Mateus et al 2013), Erythroxylaceae (Costa-Lima et al 2014), Capparaceae (Soares-Neto and Jardim 2015), Cyperus (Ribeiro et al 2015a), Fabaceae (Amorim et al 2016), and Bignoniaceae (Colombo et al 2016). Recent floristic studies focused on specific areas or vegetation types, such as the deciduous and semi-deciduous forests (Cestaro and Soares 2004; 2008), savanna (Oliveira et al 2012), riparian vegetation (Oliveira et al 2013b, Ribeiro et al 2014) and the herbaceous vegetation in Seridó (Santana and Souto 2006, Amorim et al 2006, Ferreira et al 2009, Queiroz et al 2015). Furthermore, field work in RN has produced new records (e.g.…”
