Two new species of Cyperus (Cyperaceae) from Brazil

Abstract: Two new species of Cyperus L. (Cyperaceae), both from Brazil, are described and compared to near relatives. Cyperus hooperae is described from two collections from the Chapada do Veadeiros in the State of Goiás; it is most similar to C. refractus of the southeastern U.S. Cyperus thomasii is described from a single collection from the municipality of Caruaru in Pernambuco; it is most similar to C. granatensis of Colombia. Following IUCN standards, both are considered threatened.

“…In the New World, Brazil is among the areas of high diversity and endemism in Cyperus with several new species recently published, mainly from aquatic environments [26][27][28][29][30][31][32][33]. In Brazil, the aquatic ecosystems suffer severe degradation because of activities such as illegal logging, mining, ranching, and agriculture [34][35][36][37], which reduce vegetation cover, decrease rainfall, increase evaporation and incidence of drought, and thus trigger decline in populations or even extinction of species not yet discovered [36][37][38][39][40].…”
