Plant description

Multi- or single-stemmed trees to 10 m high with smooth, dull, grey bark, shedding in flakes to reveal a paler layer, some rough bark persisting at the base. Juvenile leaves elliptic to ovate. Adult leaves to 180 mm long and 30 mm wide,narrow-lanceolate to lanceolate, dull to slightly glossy, green to blue-green, veins clear. Flowers in groups of 3-7 in the axils of the leaves. Buds to 13 mm long and 6 mm wide, smooth, ovoid to obovoid, bud-cap cone-shaped, longer than the base; Flowers white. Flowering between September and November. Fruits are ovoid to broadly cone-shaped fruit to 8 mm long to 10 mm wide , smooth, disk level to ascending, valves triangular, exserted above the rim. Seeds are dark brown to black irregularly pyramidal-shaped seed to 1.5 mm long and 1 mm wide, fine wrinkled. 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. From one collection, the seed viability was high, at 95%. Seeds are non-dormant, viable seed should germinate readily.
