Plant description

Multi-stemmed mallee to 8 m tall with rough, hard, fibrous-flaky, grey-brown bark below and smooth, orange-tan to pale grey to creamy white bark above. Juvenile leaves lanceolate to broad-lanceolate, dull, green to blue-green. Adult leaves to 130 mm long and 20 mm wide, lanceolate, highly glossy, green. Flowers axillary in umbels of 7-11 flowers. Buds to 12 mm long and 9 mm wide, with smooth or slightly angled base, bud-cap flattened, smooth or ribbed shorter than the bud-base. Flowers white appearing spasmodically depending on rainfall. Fruits are woody cup-shaped to cone-shaped fruit to 11 mm long and 10 mm wide, disc level to descending, valves 3 or 4 around rim level. Seeds are brown ovoid seed to 2 mm long and 1.3 mm wide, with deeply pitted 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 two collections, the seed viability were high, ranging from 80% to 100%. Seeds are non-dormant, viable seed should germinate readily.
