Melaleuca dealbata is a relatively slow-growing tree to 25 m (80 ft) with blue-grey foliage, hairy, pendulous branchlets and papery, layered bark.
The leaves are arranged alternately along the branches and are elliptic to oval in shape, 50–126 mm (2–5 in) long, 10–30 mm (0.4–1 in) wide and have five to seven prominent longitudinal veins.
Young shoots and twigs are densely clothed in erect, white or silver hairs.

The small, creamy-white flowers are loosely arranged in 7 to 28 groups of three on spikes up to 120 mm (5 in) long and 25 mm (1 in) wide.
The stamens are arranged in five bundles around the flower with 5 to 8 stamens per bundle.
Flowering occurs from May to December but  mainly in spring, and the fruit that follows are cup or barrel-shaped woody capsules, 2.5–3.5 mm (0.098–0.14 in) wide and long.
When the fruit matures, the fine, sawdust-like seeds are released.
