The
family Cyperaceae, or the sedges, is a taxon of monocot flowering
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, many are associated with wetlands, or with poor
soils.

polystachyos flower head
Some
well-known sedges include the water chestnut (Eleocharis dulcis)
and the papyrus sedge (Cyperus papyrus), from which the Ancient
Egyptian writing material was made. This family also includes
cotton-grass (Eriophorum), spike-rush (Eleocharis), sawgrass
(Cladium), nutsedge or nutgrass (Cyperus rotundus, a common lawn
weed), the large genus of Carex, and white star sedge
(Rhynchospora colorata).
Features
distinguishing members of the sedge family from grasses or rushes
is that members of the sedge family have triangular stems (with
occasional exceptions), and their leaves are spirally arranged in
three ranks (grasses have alternate leaves forming two ranks).
