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.
