Fimbristylis dichotoma, commonly known as forked fimbry or eight day grass, is a sedge of the family Cyperaceae that is native to tropical areas.
The annual or perennial plant, 10–80 cm tall, with numerous long stems about 2 mm in diameter, slightly three-angled, compressed below the inflorescence, node-less, smooth and has a tufted habit. The root system is fibrous, wiry, black. Short rhizomes. Leaves numerous, forming a dense tuft at the base of the stem, being at least half as long as the stem.[1]
Fimbristylis dichotoma is widely distributed in Asia, Africa and Australia as well as in other parts of the tropics.[2]
Fimbristylis dichotoma grows well on wet or even flooded soil; it is also found in uplands where the soil has good water retention. It is also found in swamps, open waste places, grassy roadsides, Imperata cylindrica grasslands and some plantation crops.[2]
