Plant Description

It is an evergreen tree that grows to a height of 35-50 m and attains a bole diameter of 1-3 m.

Stems (trunks) are straight and massive, with reddish-brown to gray bark that develops vertical fissures with age. The branching pattern is irregular, with branches spreading outwards and upsweeping towards the crown.

Leaves are small, scale-like, and arranged in overlapping spirals along the twigs. They are dark green on the upper surface with a white stomatal band on the underside. Leaves are pressed against the twigs, giving the foliage a dense, feathery appearance.

They are unisexual (separate male and female cones) and appear on the same tree. Male cones are small, yellow clustered at the tips of branches. Female cones are small and green, maturing into woody seed cones.

Seeds are flattened, irregularly ovate, and measure 4-5 mm long by 3 mm wide. They have two wings of unequal width (1-1.5 mm) that encircle the seed like a strip.
