The Family Cyperaceae, or the Sedge family, is a taxon of monocotflowering plants that superficially resemble grasses or rushes. The family is large, with some 4,000 species described in about 70 genera. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in all kinds of situations, they tend to be associated with wet places and poor soils.

The Cyperaceae (sedges) form one of the larger and more diverse plant families being actively researched at the Royal Botanic Gardens, Kew, comprising c.
As a result the Kew herbarium has a collection of c.100,000 Cyperaceae specimens which is unrivalled elsewhere and continues to grow at some 2,000 to 3,000 specimens per year.
Cyperaceae Newsletter published by the Royal Botanic Gardens, Kew and Gent University (Belgium) contains news of current research and short papers on sedges together with comprehensive lists of new names and bibliographies of newly published literature.
