Stem short, pitched up to the ground and flowers, are often part of the (red) purple, often with the length of hair below the book. High 0.2 - 1.5 m, in other places may be more.

Ecology and distribution
Reed can multiply quickly, with the seed-benihnya which spread quickly with the wind, or a trek through rimpang penetrate the soil loose. Contrary to the general belief, reed does not like to grow in poor soil, dry-stone or berbatu. Grass is pleased with the land that is fertile, many sunlit until quite calm, with a dry or humid conditions. In the lands that tarnish or submerged, or that always ternaungi, reed also did not want to grow. Weeds with the immediate former forest land that is damaged and open, the former field, the field dry up, curb and others. In places such reed can grow dominant and cover a wide area.
To a certain extent, vegetation fires can stimulate the growth of reed. shoot ilalang that grow after a fire favored by animal-animal eater grass, so that the lands used to ignite this kind are often used as a place to hunt.
Reed natural spread from India to east Asia, Southeast Asia, Micronesia and Australia. Now reed also found in northern Asia, Europe, Africa, the United States and in several islands. However, because these are the invasif, in many places reed often regarded as weeds that are making.
Type of relatives, Imperata clan members have about 8 or 9 species. Imperata cylindrica addition, several other types such as:
* Imperata brasiliensis - Brazilian bladygrass, Brazilian satintail
* Imperata brevifolia - California satintail
* Imperata conferta - plumegrass, kunay grass
* Imperata contracta - guayanilla
as weeds that are making.
One way to eradicate reed plant is the area with the types of trees that ulet, rapid growth, and has a feature that is relatively a meeting to form a fairly heavy shade. One of the recommendations is Gamal (Gliricidia spp.). Perhaps, the name "Gamal" has too ganyang dead reed.

Benefits for treatment
Rimpang: soft leather; exuviate urine, cleaning the blood, increase appetite, stopping bleeding. in addition, can also be used in the treatment efforts venereal disease (gonorrhea, urinating blood, syphilis), kidney disease, injury, fever, high blood pressure and nerve disease. All the plants used as animal feed, paper materials, and treatment for scabies.
Securities that are not in want: head sick, nausea, an increase risibility defecate, sometimes occurred in the use of clinic.
PART ARE USED:
Only the root (rimpang) used for treatment

Composition:
Roots: metabolit that have been found at the root of reed consists of arundoin, fernenol, isoarborinol, silindrin, simiarenol, kampesterol, stigmasterol, ß-sitosterol, skopoletin, skopolin, p-hidroksibenzaladehida, katekol, acid klorogenat, isoklorogenat acid, p-acid kumarat, neoklorogenat acid, acetate acid, oksalat acid, d-malat acid, citric acid, potassium (0.75% of dry weight), a large amount of calcium and 5-hidroksitriptamin. Other research results from the roots and leaves of the 5 kinds of derivative found that flavonoid derivative 3 ', 4' ,7-trihidroksi flavon, 2 ', 3'-dihidroksi kalkon and 6-hidroksi flavanol. A derivative of flavonoid, including the possibility flavon, flavonol tersubstitusi on the 3-0H, flavanon or isoflavon there is a faction in the extracts dissolved in etilasetat root reed. At the faction that extracts dissolved in water reed roots found the compound without flavon free OH group, flavon, flavonol tersubstitusi the 3-0H, flavanon, or isoflavon.
