Observations
- A small to medium-sized tree, up to 32 m tall with straight bole up to 20 m long and up to 40(-50) cm in diameter and small buttresses.
- Leaves elliptical to lanceolate, 6.5-20 cm × 2-8 cm, with 6-9 pairs of secondary veins, glabrescent, petiole 10-18 mm long.
- Inflorescences irregularly branching, up to 9 cm long.
- Flower buds up to 10 mm long.
- Nut ovoid, up to 30 mm long, with 5 equal, incrassate fruit calyx lobes, adpressed to the base of the nut.
V. pauciflora is common on river banks and in freshwater swamps, the same habitat as for V. umbonata; the latter species differs in the larger, more corky fruit calyx lobes fused to the nut, but it is otherwise very similar. V. pauciflora is one of the very few Vatica species that has been subject to tests on growth, propagation, mycorrhizae and pests and diseases. The bole is often too short and thin to be important; the density of the wood is 550-960 kg/m3 at 15% moisture content.
