Cyperus odoratus is a species of sedge known by the common names fragrant flatsedge and rusty flatsedge. This plant can be found in much of the tropical and warm temperate world, including South, Central, and North America, much of Asia and the Pacific, Australia, and parts of Africa. It is a plant of wet, muddy areas, including disturbed and altered sites. This species is quite variable and may in fact be more than one species included under one name. In general this is an annual plant approaching half a meter in height on average but known to grow much taller. It usually has some long, thin leaves around the base. The inflorescence is made up of one to several cylindrical spikes attached at a common point. Each of the spikes bears a large number of flat, oval-shaped spikelets. Each spikelet is usually light brown to reddish-brown and has a few to over 20 flowers. Each flower is covered by a tough, flat bract with a visible midvein. The fruit is a flat achene less than two millimeters long.
