|discussion=<p>Oryza sativa is cultivated in California, Arkansas, Texas, Louisiana, Mississippi, and Florida and is sometimes found as an adventive in moist or wet places, particularly in the southeastern United States, but it is not established in the Flora region. It used to be extensively cultivated in the Carolinas and Georgia, but no rice plantations are currently known to be in operation in those states. Many cultivars have been developed; there is considerable morphological, as well as ecological, variability in the cultivated crop.</p>
