Observations

• A large tree up to 50 m tall, with columnar, frequently fluted bole up to 115 cm in diameter and buttresses.
• Leaves loosely to densely clustered at tip of twigs, elliptical to obovate, with reticulate to parallel-reticulate tertiary veins often sunken above, glabrous on both sides.
• Flowers in c. 6-flowered clusters, borne on 12-20 mm long pedicels (up to 28 mm in fruit).

P. impressinervium is locally common in forest on hill slopes below 350 m. The timber is heavy (about 950 kg/m³ at 15% moisture content) and durable, but it is difficult to saw and bore and has poor nailing properties. It is moderately smooth to finish, it is difficult to peel and shrinks considerably during drying. See also the table on wood properties.
