Botanic information
Leaf: The dark green pungent linear needle-like leaves are furrowed on the upper surface and have 2-greyish stomatic bands on the underside. They are up to 4 mm (⅛ in) wide with a twisted base and the obtuse apex is bifid particularly on juvenile foliage. The leaves are arranged in a comb-like, pectinate manner along the branchlets in a V-like pattern.

Flower: The small yellowish cylindrical male catkin-like strobili is up to 30 mm (1⅛ in) long and appear singularly on the underside of the branches in the leaf axils, releasing pollen during spring. The upright cylindrical yellowish-green female cones appear in the upper branches during early summer.

Fruit: The resinous yellowish-green short-cylindrical cones mature with yellowish-brown linear-lanceolate exserted bracts. The seed-scales are up to 25 mm (1 in) long by 32 mm (1¼ in) wide and contain brownish winged seeds that are up to 8 mm (⅓ in) long and are dispersed by wind.
