The plant genus Scirpus consists of a large number of aquatic, grass-like species in the family Cyperaceae (the sedges), many with the common names club-rush or bulrush (see also bulrush for other plants so-named). Other common names are deergrass or grassweed. For other uses of the word, please see Genus (disambiguation). ... Genera See text The Family Cyperaceae, or the Sedge family, is a taxon of monocot flowering plants that superficially resemble grasses or rushes. ... The term bulrush (or sometimes as bullrush) typically refers to tall, herbaceous plants that grow in wetlands. ...

The genus has a cosmopolitan distribution, and grows in wetlands and moist soil. Some species specialize in saline, marshy, environments such as intertidal mud-flats; others prefer ponds or lake-sides and river-beds. They have grass-like leaves, and clusters of small spikelets, often brown in colour. Some species (e.g. S. lacustris) can reach a height of 3 m, while others (e.g. S. supinus) are much smaller, only reaching 20-30 cm tall. A cosmopolitan distribution is a term applied to a biological category of living things meaning that this category can be found anywhere around the world. ...

The taxonomy of the genus is complex, and under discussion by botanists. Recent studies by taxonomists of the Cyperaceae have resulted in the creation of several new genera, including the genera Schoenoplectus and Bolboschoenus; others (including Blysmus, Isolepis, Nomochloa, and Scirpoides) have also been used. At one point this genus held almost 300 species, but many of the species once assigned to this genus have now been re-assigned, and it now holds an estimated 120 species.
