Introduced and now reproducing on its own in the wild.
Echinochloa colona, commonly known as jungle rice, is a type of wild grass originating from tropical Asia. It was formerly classified as a species of Panicum. It is the wild ancestor of the cultivated cereal crop Echinochloa frumentacea, sawa millet. Some taxonomists treat the two taxa as one species, in which case the domesticated forms may also be referred to as E. colona.
