Oryza coarctata, synonym Porteresia coarctata, is a species of grass in the family Poaceae, native to Pakistan, India, Bangladesh, and Myanmar.[1] It is a perennial species that shows substantial underground rhizomatous growth. The rhizome tissues give out aerial shoots in a favourable season.[2]

Oryza coarctata is a form of wild rice that grows in saline estuaries and is harvested and eaten as a delicacy.[3] The plant is salt-tolerant, and is seen as a possibly important source of salt-tolerance genes for transfer to other rice species.[4][5] It is closely related to Oryza australiensis.[6] 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.[7]
