|discussion=<p><i>Zizania aquatica</i> is native from the central plains to the eastern seaboard. It is sometimes planted for wildfowl food. The records from western North America reflect such plantings. Most, possibly all, have since died out. The population in northern Arizona was discovered in 1967, and persisted until the early 1990s. It is presumed to have been extirpated because the area has since been developed into a golf course, and no plants have been found downstream.</p>
