Plant description

Tree to 30 m tall with mostly smooth yellowish to cream bark throughout, some loose bark on the lower trunk. Juvenile leaves cordate to ovate, pruinose, bluish. Adult leaves to 200 mm long and 25 mm wide, lanceolate, dull to slightly glossy, blue-green. Inflorescence axillary in groups of 3 on individual stalks. Buds to 10 mm long and 8 mm wide, globular, pruinose, bud-cap conical, equal to or slightly shorter than the base. Flowers cream to rarely pink appearing in winter and spring. This subspecies is distinguished from the other four subspecies that occurs in South Australia by having distinctive waxy juvenile leaves and some adult features, short peduncles and pedicels and small-sized, near-round to cup-shaped fruits. Fruits are near-round to cup-shaped fruits to 10 mm long and 14 mm wide, pruinose when young, disc descending, valves 5 or 6 below the rim. Seeds are dark grey-brown seed. 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.
