Cyperaceae

The Family Cyperaceae, or the Sedge Family, is a family of monocot flowering plants. Many of these plants superficially resemble grasses.

The water chestnut (Eleocharis dulcis) is a sedge. It is called in French liseron d'eau, but is neither a liseron nor a chestnut. In Chinese it is called ma-ti, which means horsekick. Papyrus, the ancient Egyptian writing material was made out of the sedge, Cyperus papyrus.
