Kokoona zeylanica, known in Sinhala as කොකුන් - (Kokun) is a species of plant in the family Celastraceae. The genus was formerly classified in the family Hippocrateaceae.[1]

It is endemic to Sri Lanka. It is extant at Adam's Peak[2] and at Kanneliya.[3]

The species has been listed by the IUCN as threatened.[4]


The kokun is a large tree with a rough grey bark. It flowers from March to May.[3]


The kokun is regarded as a medicinal plant traditionally used in a number of conditions.[3][5] The seed oil from this plant is effective as a leech repellent.[1][3]

The inner bark has been used by jewellers as a polish.[1]
