Melaleuca pyramidalis is a shrub growing to 3.5 m (10 ft) tall with compact, dark grey, papery bark.
Its leaves are arranged alternately and are 29–84 mm (1–3 in) long, 8–24 mm (0.31–0.94 in) wide, flat, elliptical in shape with a short stalk.
The veins are pinnate and there are only a few scattered, indistinct oil glands.

The flowers are red to pink, arranged in spikes up to 60 mm (2 in) in diameter with 20 to 50 individual flowers.
The petals are 2.8–6.3 mm (0.1–0.2 in) long and fall off as the flower ages and there are 35 to 42 stamens in each flower.
 Flowering occurs in late winter and is followed by fruit that are woody capsules, 3.8–5 mm (0.1–0.2 in) long in loose clusters along the stem.

M. pyramidalis can be distinguished from the similar M. citrina by its obscure oil glands (prominent in M. citrina) and yellow stamen tips (dark red in M.citrina).
