Motivation: Geographic occurrences are essential for biodiversity studies, but publicly available repositories like GBIF often contain errors and biases, especially for taxonomically complex groups like Carex L. (Cyperaceae). This work provides an expert-curated global dataset of occurrences compiled from different sources to enhance data accuracy and usability. The final dataset includes 384,067 occurrences of 1790 Carex species. Main Types of Variables Contained: The dataset includes species occurrence records with geographic coordinates, taxonomic identifications, and curation flags (e.g., introduced, erroneous records). Spatial Location and Grain: The dataset covers a global scale, using the WGS84 projection. Spatial resolution is standardised to a minimum of three decimal degrees (~1 km, if possible). Time Period and Grain: Online records span from 1950 to 2020, but some manually georeferenced records are earlier (1850). There is also fieldwork data after 2020, specifically up to 2023. Major Taxa and Level of Measurement: Cyperaceae: Carex. Most records have species-level identification, and some of them are identified at subspecies or variety levels. Software Format: Data are supplied as comma-separated values files with UTF-8 encoding.

Carex huancabambica (Cyperaceae), a new species from the Peruvian and Ecuadorian Andes

2025 , Luis González-Gallego , Carmen Benítez-Benítez , Anton A. Reznicek , Asunción Cano , Oleas Gallo, Nora Helena , Santiago Martín-Bravo , Pedro Jiménez-Mejías

The Huancabamba Depression in Neotropical South America, a natural barrier between the Northern and Central Andes, serves as a refuge for high levels of angiosperm diversity. However, this biodiversity remains understudied, especially in complex and species-rich genera, such as Carex L. (Cyperaceae). This genus is notably underrepresented in taxonomic and systematic research on the Neotropics. In this study, we employed an integrative systematic approach combining molecular and morphological data to elucidate the taxonomic status of several Carex populations from Ecuador and northern Peru, which exhibit morphological affinities with the sect. Porocystis Dumort. (Castanea Clade). We conducted a phylogenetic analysis using two nuclear (ITS and ETS) and one plastid (matK) DNA regions and carried out a detailed morphological comparison with Neotropical relatives within the section. Both phylogenetic and morphological results supported the systematic distinctiveness of the focal populations. As a result, we describe a new species, Carex huancabambica Gonz.Gallego & Jim.Mejías, sp. nov. and provide its taxonomic treatment. This study contributes to disentangling the biodiversity of the genus Carex in the Neotropics.
