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. Xerophila, from the Greek 'xeros, meaning dry and 'phila', meaning loving, alluding to its arid desert habitat.

Large shrub or small spreading tree to 6 m, with fibrous or papery bark. Leaves alternately or spirally arranged; narrow elliptic to 5.2 mm long and 1.5 mm wide. Inflorescences are arranged in heads near the ends of the branches, each head usually consisting of one to nine bright yellow, pale lemon-yellow or whitish flowers, turning pink with age. Flowering between October and November. Fruits are grey-brown woody, cup-shaped capsule to 3.5 mm diameter, Seeds are tiny brown cylindrical to pyramidal-shaped seed to 0.8 mm long and 0.4 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 two collections, the seed viability was average to high, ranging from 80% to 100%. Seeds are non-dormant, viable seed should germinate readily.
