Rottboellia cochinchinensis is a species of grass known by the common names Itchgrass,[1][2]Raoul grass,[3]corngrass,[4]Kokoma grass, Guinea-fowl grass, jointed grass, Shamwa grass[1] and Kelly grass.[5] It is a tall, tufted annual grass whose stems (culms) grow up to 3 metres (9 ft 10 in) in height with leaf-blades of up to 45 centimetres (1 ft 6 in) in length.[6] The species flowers at the apex of culms in the form of spike-like racemes composed of paired spikelets.[4] The common name Itchgrass comes from the bristly (hispid) leaf-sheath which can be irritating to the skin.[4]
Rottboellia cochinchinensis is native to tropical Asia and Africa and has also been introduced to the Americas where it is often considered to be an invasive species.[1][7][2] It is a major weed of a wide range of crops including maize, rice, sorghum and sugar cane.[1][8]
