Oryza grandiglumis is a wild rice species from tropical South and Central America that grows in wetlands and can float on water. It is an annual with short rhizomes and long, buoyant stems, so it is grown only in wetland or aquatic conditions.
Oryza grandiglumis is a type of wild rice of the genus Oryza found in tropical countries of South- and Central- America, namely Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Paraguay, Venezuela, and Peru. Studied in 1998 in Caño Negro, in northern Costa Rica, it is an annual plant with short rhizomes; its culms can reach 790 centimetres (311 in) and are 4–9 millimetres (5⁄32–23⁄64 in) in thickness. They have developed aerenchyma which allows them to float.
