Etymology

Melaleuca, from the Greek 'melas' meaning black and 'leucon,' meaning white, alluding to the contrasting colours of the bark of the first species described, which is said to have had white branches against a black trunk. Acuminata, from Latin meaning tapering to a long point, referring to the leaves having an acute apex.

Distribution and status

Found in the southern part of South Australia growing in mallee woodland and heath on sand. Also found in Western Australia, New South Wales and Victoria. Native. Common in South Australia. Rare in New South Wales. Common in the other States.

Plant description

Shrub to 4 m high with rough and scaly bark. Leaves opposite, narrowly elliptic, to 10 mm long and 4 mm wide, apex acuminate, mucronate, glabrous. Inflorescence in lateral clusters of 3–6 white, or sometimes tinged with pink, flowers. Flowering in spring. Fruits are grey-brown, smooth, sub-globular woody capsule to 4 mm in diameter with valves to 2 mm wide; sepals persistent, in clusters on old wood Seeds are tiny brown rectangular or pyramid seed to 1 mm long and 0.5 mm wide. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between January and December. Collect capsules that are large and hard, with closed valves. Place the capsules in a tray and leave to dry for at least two weeks or until all the valves are open. Then place all the capsules into a bucket with a lid if possible and shake hard to dislodge the seeds from the capsules. Use a sieve to separate the seeds from the capsules. The fine material will contain the seeds and other flowering material. It is very difficult to separate the seeds from this other material as the size, shape and weight are very similar. However the seeds will be a darker brown. 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 75%. Seeds are non-dormant, viable seed should germinate readily.
