Species
About 600 species; see text

Cyperus is a large genus of about 600 species of sedges, distributed throughout all continents in both tropical and temperate regions. They are annual or perennial aquatic plants, growing in still or slow-moving water up to 0.5 m deep. The species vary greatly in size, with small species only 5 cm tall, while others can reach 5 m tall. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish, and wind pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Image File history File links Cyperus_diffusus1. ...

Uses

The Papyrus Sedge C. papyrus of Africa was of major historical importance in providing papyrus. The Chufa C. esculentus, native to India, has edible tubers and is grown for these; several other species are eaten to a smaller extent. Cañita, C. giganteus, is used by the Chontal people of Tabasco, Mexico for weaving sleeping mats and sombreros. Few other species are of economic value, though some are grown as ornamental plants. Interest in the larger, fast-growing species as biomass crops for paper and fuel production is however emerging. Africa is the worlds second-largest and second-most populous continent, after Asia. ...
