Tree to 15 m tall. Bark not fissured. Branches spreading to erect. Male and female cones on the same tree. Leaves to 2.5 mm long, usually somewhat glaucous, dorsal surface prominently but not acutely keeled. Fruits are male cones solitary or clustered, ovoid, to 2 mm long. Female cones usually clustered on clustered fruiting branchlets, ovoid to depressed-globular, to 20 mm diameter, persistent and holding seeds for several years after maturity. Cone bracts 6, thick, with a distinct, short, broad, conical, dorsal protuberance below apex. Seeds are brown ovoid seeds to 3 mm long and 2 mm wide, with wing to 3 mm wide on either side.
Seed collection and propagation
Collect seeds between January and December. Collect cones that are not open but large, hard and dark. These will contain maturing seeds. Place the cones in a tray and leave to dry for 3-5 weeks to allow the cones to open naturally. Then shake the cones in a bucket to dislodge the seeds. Use a sieve to separate the seeds from the cones. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed viability can be low. Viable seed should germinate readily, if stored in a fridge prior to sowing in winter.
