Retrophyllum minus

Retrophyllum minus, the bois bouchon, is a species of conifer in the family Podocarpaceae. It is endemic to New Caledonia.

It is a sparsely branched small tree rarely exceeding ten feet (three meters in height) with a flared trunk remindful of Bald Cypress and water Tupelo which tapers towards the top and has rough bark. It produces pear-shaped fruits that are dark-red when mature.

The species occurs near rivers and lakes of the Plaine des Lakes in the south of Grande Terre. It is a rheophyte (grows in running water), the only such conifer known.

It is threatened by habitat loss to mining and wildfire. It is a protected species.
