Xylocarpus moluccensis MELIACEAE
Local name: Nyireh batu
Two small mangrove trees with very large fruit can be found growing along the Borneo coast. The large angular corky nuts are a very common drift seed on sandy beaches.
Xylocarpus moluccensis has the smaller fruit which reach a maximum of 11 cm diameter. X. moluccensis is also much less common than Xylocarpus granatum. Xylocarpus granatum fruit reach 25 cm in diameter.
The individual nuts/seeds of the two species are similar and cannot be told apart.
