General Information

Oryza barthii is an annual, clump-forming grass with erect to semi-erect culms that form new roots at the lower nodes; it can grow 60 - 150cm tall.
Because they are a source of resistance to, or tolerance of, biotic and abiotic stresses, the most important use of the various species of wild rice is probably in breeding programmes to improve the species of cultivated rice (Oryza sativa, Oryza glaberrima). The edible seed of this species is sometimes harvested from the wild for local use. It is not cultivated; in fact, the grain has very limited use because of the difficulty in harvesting it. It is sold at a very high price, however, and is considered a product of unusually choice quality[

].
The panicle is short; and the ripe grain, which is small, falls out of the husk very easily. For this reason it is impossible to cut the heads for thrashing without losing most of the grain. To obviate this difficulty, local people, in those regions where the plant is common, paddle among the ripe grain in their canoes, shaking the panicles over a small calabash, or basket, held in one hand. Most of the grain falls into the basket and is saved. If it is late in the season, the ripe grain will float on the surface of the water and that which falls outside of the basket may be recovered[
