|Imperata cylindrica, also known as cogongrass or kunai grass, is a species of grass in the genus Imperata. It is placed in the subfamily Panicoideae, supertribe Andropogonodae, tribe Andropogoneae.|
It is a perennial rhizomatous grass native to east and southeast Asia, India, Micronesia, Australia, and eastern and southern Africa. It grows from 0.6–3 m (2–10 feet) tall. The leaves are about 2 cm wide near the base of the plant and narrow to a sharp point at the top; the margins are finely toothed and are embedded with sharp silica crystals. The main vein is a lighter colour than the rest of the leaf and tends to be nearer to one side of the leaf. The upper surface is hairy near the base of the plant while the underside is usually hairless. Roots are up to 1.2 meters deep, but 0.4 m is typical in sandy soil.
The plant has become naturalized in the Americas, Northern Asia, Europe and Africa in addition to many islands and is listed as an invasive weed in some areas. In the U.S. it survives best in the Southeast (and, according to a 2003 survey, has overtaken more acreage in that region than the notorious kudzu), but has been reported to exist as far north as West Virginia and Oregon. Worldwide it has been observed from 45°N to 45°S. It grows on wet lands, dry lands, areas of high salinity, organic soils, clay soils and sandy soils of pH from 4.0 to 7.5. It prefers full sun but will tolerate some shade.
It spreads both through small seeds, which are easily carried by the wind, and rhizomes which can be transported by tilling equipment and in soil transport.
In the Southeastern United States, state governments have various eradication efforts in place, and deliberate propagation is prohibited by some authorities. Control is typically by the use of herbicides. Burnoff is seldom successful since the grass burns quite hot causing heat damage to trees which would ordinarily be undamaged by a controlled burn and recovers from a burn quickly.
The legume vine Mucuna pruriens is used in the countries of Benin and Vietnam as a biological control for Imperata cylindrica.

I don't know why such a beautiful picture like the one you present us here has not attracted more interest. The simplicity of the subject as well as of the composition, the superb colours and the natural aspect make it very pleasant. Moreover, your notes are interesting to read.
