Melaleuca thymoides is a spreading shrub usually no more than 1 m (3 ft) tall and wide, although sometimes it is up to 3 m (10 ft) tall, with the branchlets usually ending in a sharp spine. The leaves are arranged alternately along the stem, 2.4–13.8 mm (0.09–0.5 in) long, 0.7–3.6 mm (0.03–0.1 in) wide, lance-shaped to narrow oval and ending with a sharp point. The leaves have a central and two marginal veins. The flowers are bright yellow, and arranged in a spike or a head near the ends of branches. The heads are up to 15 mm (0.6 in) in diameter and contain 2 to 15 groups of flowers in threes. The stamens are arranged in five bundles around the flower, each bundle with 7 to 11 stamens. Flowering occurs from August to February but mainly in October and November. The fruit which follow are woody capsules 2.3–4 mm (0.09–0.2 in) long in clusters of about six which are about 10 mm (0.4 in) in diameter. The rim of the fruit are flat.
