Synonyms [1] [2] | |

Porteresia coarctata is a species of grass in the family Poaceae, native to India, Sri Lanka, Bangladesh, and Myanmar. [3]
Porteresia coarctata is considered by some botanists to be the only species in the genus Porteresia. Other authors maintain instead that it should belong in the rice genus Oryza, [3] as Oryza coarctata Roxb. [4] It is a form of wild rice that grows in saline estuaries in Bangladesh and India and is harvested and eaten as a delicacy. [5] The plant is salt-tolerant, and is seen as a possibly important source of salt-tolerance genes for transfer to other rice species. [6] [7] It is closely related to Oryza australiensis. [8] The leaves of this species secrete salt through special microhair like structures that have three morphotypes, and a method to isolate these structures has been developed. [9] Porteresia coarctata is a perennial species that shows substantial underground rhizomatous growth. The rhizome tissues give out aerial shoots in a favourable season. [10]
