Plant description

Small trees or trees to 30 m high, with a single trunk. Bark brown, rough and furrowed. Leaves in whorls of 3 (sometimes 4 or 5 when juvenile), usually glaucous (bluish grey), juvenile leaves to 8 mm long, mature leaves to 3 mm long with apex broadly acute, dorsal surface not keeled. Fruits are dark brown, depressed-globose to ovoid cone to 2.5 cm diameter, surface smooth, solitary, compressible, rarely remaining on the plant long after maturity. Seeds are reddish brown ovoid seed to 6 mm long, with a wrinkled surface and two large wings 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. Viable seed should germinate readily, if stored in a fridge prior to sowing in winter.
