Scleria (Cyperaceae) in the state of Pará, Amazon, Brazil

Abstract

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.

Cyperaceae in Serra dos Martírios-Andorinhas, Pará, Brazil

“…They also reinforce that a deeper understanding of Brazilian flora can only be reached with detailed local and regional taxonomic floristic studies. Recently, new records, nomenclatural novelties, new species, and detailed and illustrated local floras were published for the state of Pará (Maciel-Silva et al 2018Nunes et al 2016aNunes et al , b, 2017Nunes et al , 2019Schneider et al 2017Schneider et al , 2019Schneider & Gil 2021;Braga-Silva et al 2019;Maciel-Silva et al 2022). Amaral et al (2008), in the only published floristic survey for the SMA, recorded 149 plant species present in different ecosystems, with only four belonging to Cyperaceae, in the genera Bulbostylis Kunth and Cyperus L. Thus, aiming to expand the taxonomic knowledge of Cyperaceae in the Amazon, this work aimed to carry out a taxonomic study of the sedges occurring in Serra dos Martírios-Andorinhas, presenting identification keys for the species, succinct descriptions with main diagnostic characteristics, geographic distribution data, habitat, and illustrations.…”
