Census of South Australian plants (external link)     [genus Melaleuca]
Name derivation:
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.  Lanceolata from the Latin 'lanceolatus' meaning shaped like a lance-head; referring to the shape of the leaf.
Distribution:
Found in the southern part of South Australia, growing on limestone ridges, coastal cliffs and dunes, salt flats, near salt lakes, mallee or open woodland on limestone, clay or loam, brown or grey or white sand. Also found in Western Australia, Queensland, New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Shrub or tree to 10 m high, glabrous except for the softly pubescent young vegetative parts and fruit capsules. Leaves alternate, linear to narrow-elliptic to 15 mm long and 3 mm broad, acute and reflexed at the apex, concave above, thicker at the margins. Inflorescence in dense leafy spike to 40 mm long and 18 mm wide with 10-20 white or cream flowers. Flowers in summer.
Fruit type:
Grey-brown, woody, spherical capsule to 5 mm diameter.
Seed type:
Dark brown pyrimid seed to 1.5 mm long and 0.5 mm wide.
Embryo type:
Folded.
Seed collecting:
Collect capsules that are large and hard with closed valves. Mature capsules are usually found down the stems.
Seed cleaning:
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.
Seed viability:
From two collections, the seed viability were high, ranging from 85% to 95%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
