Saccharum spontaneum
Saccharum spontaneum (wild sugarcane, Kans grass) is a grass native to the Indian Subcontinent. It is a perennial grass, growing up to three meters in height, with spreading rhizomatous roots. In the Terai-Duar savanna and grasslands, a lowland ecoregion at the base of the Himalaya range in Nepal, India, Bangladesh and Bhutan, kans grass quickly colonises exposed silt plains created each year by the retreating monsoon floods, forming almost pure stands on the lowest portions of the floodplain. Kans grasslands are an important habitat for the Indian rhinoceros ("Rhinoceros unicornis"). In Nepal, kans grass is harvested to  thatch roofs or fence vegetable gardens. Elsewhere, its ability to quickly colonize disturbed soil has allowed it to become an invasive species that takes over croplands and pasturelands, as has been documented in the Republic of Panama. Uses. "Saccharum spontaneum" has a considerable number of regional names in the Indian Subcontinent, for instance "kash" (কাশ) being common in Bengali, "kohuwa" (কঁহুৱা) in Assamese and "kasatandi" (କାଶତଣ୍ଡୀ) in Odia. It is used in Ayurveda. This plant has hybridized with "Saccharum officinarum", a domesticated sugarcane. The hybridization may have produced "Saccharum barberi" and "Saccharum sinense".
