Introduction

Cyperaceae are one of the ten largest plant families in the world. The Global Cyperaceae Database (GCypD) is built on the World Checklist of Vascular Plants which has been imported to the Aphia platform of the World Register of Marine Species through World Flora Online (WFO). The international WFO Taxonomic Expert Network (TEN) for Cyperaceae will assess, edit and update the taxonomic information for this important family.

A Global Cyperaceae Checklist and online taxonomic treatment

Datasets for the Cyperaceae from across the world were integrated in the Global Cyperaceae Database from 2023 onwards. Names were matched using POWO as initial reference. Entries were completed to differing levels by different authors (see authorship at the bottom of the corresponding data page). Distribution data originally compiled from POWO. Taxonomic concepts were initially derived from the data sources and updated according to subsequent treatments and under the criterion of the author in charge of the corresponding taxon.
