The Americas.
While beans are native to the Americas, rice is not.
Rice was introduced to the Caribbean and South America by European colonizers at an early date with Spanish colonizers introducing Asian rice to Mexico in the 1520s at Veracruz and the Portuguese and their African slaves introducing it at about the same time to Colonial Brazil.
More recent scholarship suggests that African slaves played a more active role in the establishment of rice in the New World and that African rice was an important crop from an early period.
In either case, varieties of rice and bean dishes were a staple dish among the peoples of West Africa, and they remained a staple among their descendants subjected to slavery in the Spanish New World colonies and elsewhere in the Americas. 
Lemuelites () were a subdivision of Lamanites, a purported people of the ancient Americas referenced in the Book of Mormon.
To save time and prevent confusion those who were sought to destroy Nephi's people were often just called "Lamanites".

The Native Americans of what is now the Eastern United States may have practiced extensive agriculture with forms of wild rice.
Patna rice, a variety of the species "Oryza sativa", and one of the varieties of long-grain white rice, is extensively cultivated in the Indo-gangetic plains, in and around Patna, capital of Bihar state, India.
Patna rice is known for its elongated kernel with grain length greater than 6 mm, and has been used as staple food by the local people for thousands of years.
Sometimes, Patna rice is also called "Parimal" rice locally.
This mildly flavoured rice comes from the Bihar region of the Ganges plains.
It has a robust, long and narrow, opaque grain that keeps its shape well for curries.
Basmati rice is closely related to the Patna rice but has a stronger aroma.
The Mughal chronicler Abul Fazal who collected the various types of rice grown in the Gangetic belt has described the rice cultivated in Patna in glowing terms.
William Fullarton of Skeldon UK made his fortune by dealing in Patna rice.
He chose Patna as the name of the coal-miners' hamlet he built in East Ayrshire, Scotland.
Since most of the rice sold in Europe came from this region at one time, the term "Patna rice" also sometimes loosely designates any long-grain aromatic rice.
Another example of long-grain rice is American long-grain rice which include Carolina rice.
It is believed that Patna rice was the first type of rice cultivated in America [http://www.dailybread.co.uk/food/rice.htm], and acquired the name Carolina rice.
The seeds of Patna rice were taken to America, grown in Carolina and exported to Britain before the American Civil War.
Thus the term Carolina rice is also sometimes used to denote this variety of rice. 
Rice was established in Arkansas in 1904, California in 1912, and the Mississippi Delta in 1942.
Rice cultivation in California in particular started during the California Gold Rush.
It was introduced primarily for the consumption of about 40,000 Chinese laborers who were brought as immigrants to the state; only a small area was under rice cultivation to meet this requirement.
However, commercial production began only in 1912 in the town of Richvale in Butte County.
Since then, California has cultivated rice in a big way, and as of 2006, its production of rice was the second largest in the United States.
