Zizania latifolia (Griseb.) Turcz. ex Stapf

Zizania latifolia (Griseb.) Turcz. ex Stapf. Zizania latifolia, known as Manchurian wild rice, is the only member of the wild rice genus Zizania native to Asia. It is used as a food plant. Both the stem and grain are edible. Gathered in the wild, Manchurian wild rice was an important grain in ancient China. A wetland plant, Manchurian wild rice is now very rare in the wild, and its use as a grain has completely disappeared in Asia, though it continues to be cultivated for its stems. A measure of its former popularity is that the surname Jiǎng, one of the most common in China, derives from this crop.
