Cyperus bipartitus
Also called Brook Flatsedge, Shining Flatsedge, River Cyperus
Cyperus bipartitus is a small annual sedge that forms tufts of stems up to about 25 cm tall, found in wet places such as lake shores, sandbars and ditches. It is grown mainly as a damp-soil or pond-margin plant, with moist conditions as the key to growing it.
Cyperus bipartitus, also known as slender flatsedge, river cyperus, or shining flatsedge, is a species of flowering plant in the sedge family Cyperaceae. It is native to the Americas, from southeastern Canada to northern Argentina. In the United States, its season runs from July to October but little else is known about its ecology. It is often confused with Cyperus diandrus, both of which have chestnut-brown scales protecting the flowers. It may also be confused with Cyperus gracilis, another species known as "slender flatsedge". The name "shining flatsedge" refers to the shiny appearance of its heavily pigmented floral scales.
The taxon known as Cyperus bipartitus was described as a variety of Cyperus diandrus by John Torrey in 1836.
Cyperus bipartitus is native to the Americas, from southeastern Canada to northern Argentina. It is found in wet environments such as lakes, sandbars, and ditches at elevations to 1,500 metres (4,900 ft). In the United States, its season runs from July to October, but in Mexico, its season extends into January.
