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 distinct morphotypes, and a method to isolate these structures has been developed.[7] The rhizomes store a significant amount of salt and also control the flow of salt to the developing shoots.[8][9]
