The four species of wild rice compose the genus Zizania (common names: Canada rice, Indian rice, and water oats), a group of grasses that grow in shallow water in small lakes and slow-flowing streams. Often, only the flowering head of wild rice rises above the water. True rice, genus Oryza, is also a grass; the two genera Oryza and Zizania are closely related, sharing the tribe Oryzeae.

Texas wild rice (Z. texana) is a perennial plant only found in a small area along the San Marcos River in central Texas. and one species is native to Asia:Manchurian wild rice (Z. latifolia; incorrect synonym: Z. caduciflora), is a perennial native to China.
