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. Glomerata from the Latin 'glomeratus' meaning heap or having been made into a ball; referring to the globular flower spike.
Distribution:
Found in the northern part of South Australia, growing on red sand, clay or sandy loam in rocky river beds, shallow depressions and sandy flats. Also found Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Uncommon in Queensland and New South Wales. Common in the other states.
Plant description:
Shrub to 8 m high with grey hairy stems. Leaves alternate, linear to narrowly oblanceolate to 50 mm long and 2 mm wide, sessile, hairy. Inflorescence in dense terminal and axillary globular heads with yellow flowers. Flowers in winter and spring.
Fruit type:
Tawny smooth capsule to 2.5 mm diameter, truncate, slightly compressed in dense clusters mostly near the bases of woody branches.
Seed type:
Tiny brown ovoid seed to 1 mm long and 0.5 mm wide.
Embryo type:
Folded.
Seed collecting:
Collect capsules that are large and hard with closed valves.
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 one collection, the seed viability was high, at 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
