Plant description

Single or multi-stem tree to 10 m tall with smooth light grey to pinkish-grey bark or loose and rough near the base. Juvenile leaves opposite for few pairs then alternate, ovate, to 12 cm long and 6 cm wide, green. Adult leaves alternate, broadly lanceolate to lanceolate, to 15 cm long and 2 cm wide, dull to slightly glossy green to blue-green. Inflorescences terminal panicles with white flowers. Bubs to 7 mm long and 4 mm wide, bud-cap cone-shaped, shorter than the base. Flowering between May and December. Fruits are woody cone-shaped to barrel-shaped fruit to 9 mm long and 6 mm wide, disc ascending, valves 3 or 4 below the rim. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between January and December. Collect mature fruits that are dark and hard (difficult to break with a finger nail), with the valves un-open any time of year. Leave the fruits in a breathable container in a dry room for one to two weeks. This allows the valves on the fruit to open and release the seeds. Separate the seeds by placing all the materials into a bucket and shaking it to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds (soft) and frass (hard) usually distinguishable from each other but can be very similar in shape and colour. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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. Seeds are non-dormant, viable seed should germinate readily.
