3 Specimens from kerangas in Sarawak may deviate by a stouter habit and less contrasting colour of the dry leaves. 2 Because var. polyspherula is mainly characterized by its smaller fruits, it is often difficult to tell whether specimens with fruits just over 25 mm long belong to var. sumatrana or to var. polyspherula. 1 The leaves, as in var. sumatrana, are usually brittle when dry and often fragmented in herbaria; they are usually greenish above and contrast well with the light to chocolate-brown colour of the lower surface. The hairs of the leaf buds and young twig apex are rather long, 0.2-0.6 mm, slightly longer than in the other varieties.
