Four new species of Mapania Aubl. from montane habitats in Guyana are described. A new combination at new rank, Scleria subeggersiana (Kük.) Camelb. & Goetgh., is published for Scleria microcarpa Nees ex Kunth var. subeggersiana Kük. The new combination Cephalocarpus spongiosus (M. T. Strong) M. T. Strong and the replacement name Rhynchospora hollowellii M. T. Strong, replacing the later homonym R. capillifolia W. W. Thomas, are published. Typifications are made for 30 names representing 27 currently accepted names in Cyperaceae occurring in the Guianas, South America: Becquerelia glomerulata Brongn. var. euglomerulata f. rubra H.
