Observations

• A fairly large tree up to 35(-45) m tall, with columnar bole up to 85 cm in diameter, with buttresses.
• Leaves more or less clustered at tip of twigs, spatulate, with slender, reticulate tertiary veins often parallel to secondary veins, initially finely hairy beneath but glabrescent.
• Flowers in 1-5-flowered clusters, borne on short (2-5 mm) pedicels.
• Fruit globose to obovoid, 1.2-2.2 cm long, glabrous.

P. microphyllum occurs very scattered in lowland and swamp forest, usually below 500 m but occasionally up to 1000 m. It is only very locally common, e.g. in Johor (Peninsular Malaysia). The timber is usually fairly heavy for nyatoh, with a density of 530-920 kg/m³ at 15% moisture content.
