SCIRPUS is a genus 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 plant genera so-named). Other common names are DEERGRASS or GRASSWEED. They have grass-like leaves, and clusters of small spikelets, often brown. 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.
The genus has a nearly cosmopolitan distribution , found on every
The taxonomy of the genus is complex, and under review 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 it have now been reassigned, and it now holds an estimated 120 species.
