It grows in primary rainforest with canopy heights to 50 metres or more, occurring from lowlands to montane forested ridges at elevations to 2,100 metres

Nageia wallichiana is an erect evergreen and glabrous tree tall up to 50 m with a cylindrical stem and thin colourless juice. The bark is smooth with a brown and white mottled appearance and 0.5-inch thickness. The bark is hard and scaly with a dark or reddish-brown colour and peeling into thin flakes. The inner bark is pinkish or reddish in colour with 5–6 mm thickness and slightly fibrous. The wood as aromatic, grey coloured, and moderately hard. The anatomy of the wood is described as extremely fine, with numerous rays and faint annual rings. The weight of the wood is recorded as 32 lbs per m3.

The crown is described as conical or irregularly rounded. Leaves are opposite decussate, subopposite, or rarely alternate towards the end of branchlets. The length of the leaf is recorded as 3-7 inches and width 0.75- 2 inch. The petiole is 5– 10 mm long and twisted 900 at the base. Leaf shape is narrowly elliptic to ovate-lanceolate with acute or obtuse apex. Leaves are coriaceous, tapering at both ends, and have numerous longitudinal nerves. Leaf colour is dark shining green. Stomata seen on both surfaces and is more conspicuous in the underside.

Pollen cones are arranged axillary, on a 4–10 mm long peduncle in clusters of up to 7–10. The pollen cones become cylindrical at its full length and consist of two pollen sacs. Seed cones are axillary, solitary, and arranged in long peduncles, with a few deciduous bracts near the base of the peduncle. The cone bracts fuse to a green swelling and later red or purplish receptacle. The ovoid seeds with 1-inch length are formed at the end of receptacle and enclosed in a green epimatium which later turns into a purple coloured fleshy structure. The fruiting season is January to February.

Based on data from 64 collection localities, its climate preferences include a mean annual temperature of 24.7°c, with an average minimum in the coldest month of 19°c, and a mean annual precipitation of 2711mm. It is hardy to Zone 9 (cold hardiness limit between -6.6°c and -1.1°c. Plants can succeed in soils with low levels of nutrients. A dioecious species, both male and female forms need to be grown if fruit and seed are required.

Propagation: Through seeds.
