Canarium acutifolium Merr.

A tree which grows to 20 m high and occasionally to 40 m high. The trunk can be 20-90 cm across. It can have buttresses up to 3 m high. The small branches are 1.5 cm thick. The leafy structures (stipules) at the base of the leaf stalk are like threads and 1.5-3.5 cm long. The leaves have 3-5 leaflets. These are oval and 12-30 cm long by 4-11 cm wide. They are papery. The base of the leaflet is slightly oblique but rounded and the tip is long and slender. There are between 11 and 20 pairs of veins which curve near the edge of the leaf. The flower clusters are a shaped like a pyramid and in the axils of leaves. The male clusters are up to 50 cm long and the female clusters 40 cm long. There are many small flowers 4 mm long. The fruit clusters are rigid and have many fruit. The fruit are oval and round in cross section. They are 12-15 mm long by 8-10 mm wide. There is one seed inside. Three different varieties occur based on the number of stamens and number of veins in the leaflets.

Dense, primary forest, also in the more open, secondary formations; especially along forest-edges, river-banks and in clearings; mostly on wet (sometimes temporarily inundated) clayey soil; at elevations up to 200 metres, occasionally to 700 metres.

Plants can be grown by seeds.
