“…Nevertheless, there are still few studies developed in the Brazilian Amazon region. Some local studies have been developed focusing on the Cyperaceae in the state of Pará, such as: (1) Nunes et al (2016) for the "cangas" of Serra dos Carajás; (2) Silva et al (2021) for the "campos de natureza" in the municipality of Cametá; and (3) Schneider et al (2017), Maciel-Silva et al (2018), and Schneider & Gil (2020b) focusing on Rhynchospora, Eleocharis, and Scleria for the "restingas", respectively. These studies provided taxonomic and nomenclatural novelties, and presented new records for the Flora of Pará, which demonstrates the need for further taxonomic research.…”

The present study analyzes the diversity of Scleria in the state of Pará and presents taxonomic treatments for all recorded species. The analysis was based on extensive herbarium studies (CEN, HBRA, HCJS, HSTM, IAN, IBGE, INPA, MFS, MG, RB, and UB) and field expeditions to several municipalities of the state of Pará. Specimens were identified using relevant literature, protologues, and type specimens available online. We recognize 30 species of Scleria arranged in two subgenera and nine sections. Four species (i.e., Scleria arguta, S. burchellii, S. longigluma, and S. vaginata) represent new records for Pará, and a new species is proposed (i.e., Scleria sp.). An identification key, descriptions, illustrations, and comments on diagnostic characters, geographic distribution and habitat for all species are also provided.
