Melicope jonesii is a tree that typically grows to a height of 35 m (115 ft). The leaves are arranged in opposite pairs and trifoliate on a petiole 50–110 mm (2.0–4.3 in) long. The leaflets are elliptical, 100–175 mm (3.9–6.9 in) long and 40–80 mm (1.6–3.1 in) wide. The flowers are arranged in panicles 20–35 mm (0.79–1.38 in) long in leaf axils and are bisexual, the sepals round and about 1 mm (0.039 in) long and fused at the base, the petals greenish or cream-coloured, 4–5 mm (0.16–0.20 in) long and there are four stamens. Flowering has been recorded in January and February and the fruit consists of up to four follicles 8–10 mm (0.31–0.39 in) long and fused at the base containing shiny black seeds.[2][3]
