Description

Elaeocarpus polystachyus is a medium-sized rainforest tree to 23 m tall that occurs from lowland to hill dipterocarp forest to 840 m altitude, including peat swamp and coastal forest, but rarely up to montane forest. This sun-loving species usually grows in small populations, on hill slopes and ridges but is more common in secondary forest than in primary forest.

The outer bark of E. polystachyus is grey-brown with pale brown inner bark and cream sapwood. The stipules are narrowly triangular, dark brown or black, and sometimes persist even after leaf maturity. The simple leaves are spirally arranged and loosely grouped towards the twig tips. The flowers are 4-merous, but mutation in flower part number is recorded in two specimens: one from Slim Hills Forest Reserve, Perak (Whitmore FRI 717) has 5-merous flowers, and the other from Bukit Timah, Singapore (Samsuri Ahmad SA 1353) has a mixture of 4- and 5-merous flowers. The oblong or ellipsoid fruits are green and hairy when young, turn glabrescent and once were recorded as yellow when mature (Suppiah FRI 11360) instead of blue as in most Elaeocarpus fruits. Often only one seed is developed in each fruit and the seed is enclosed within a hard stone that develops from the inner mesocarp.

This species is endemic to Peninsular Malaysia and Singapore and is locally abundant in Bukit Timah Nature Reserve, Singapore, but becomes less common from Johor northwards to Kelantan and Perak.
