Plant description

Multi-trunked mallee to 6 m tall with loose rough bark at the base and smooth coppery to cream bark above and a mix of juvenile and adult leaves in the crown. Juvenile leaves ovate to orbicular, pruinose, bluish. Adult leaves to 90 mm long and 12 mm wide, narrow lanceolate to linear, glossy green. Inflorescences axillary in groups of 7-13 white flowers. Buds to 7 mm long and 5 mm wide; bud cup conical equal in length to the base. Similar to Eucalyptus leptophylla which has smooth bark, less waxy juvenile leaves and has only adult leaves in the mature crown. Fruits are cup-shaped to barrel-shaped fruit to 6 mm long and 96 mm wide; disc descending, valves 3-4 below rim. Seeds are grey-brown ovoid seed to 4 mm long and 2 mm wide, with fine wrinkled surface. 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 average, at 63%. Seeds are non-dormant, viable seed should germinate readily.
