Description
[edit]M. cumingii is an evergreen shrub or small tree growing up to 25 m (82 ft) tall, with a trunk diameter of up to 45 cm (18 in). The outer bark is grey to brown in colour and may be smooth or wrinkled, sometimes peeling away in patches. The leaves are oval in shape, measuring 4.8–35.5 cm (1.9–14.0 in) by 1.5–19.5 cm (0.59–7.68 in), and may be hairy or glabrous. The upper surface of the leaf is dark green and somewhat shiny with a paler underside. M. cumingii is dioecious and the inflorescences are racemes, produced singly or less commonly in a pair. Male plants produce inflorescences up to 21 cm (8.3 in) long, with sweet-scented white, cream, or yellowish flowers measuring up to 3.2–6.9 mm (0.13–0.27 in) in diameter and composed of 2–4 ovate sepals surrounding a cluster of 30–60 stamens. Female plants produce inflorescences up to 19 cm (7.5 in) long, with faintly sweet-scented greenish flowers with a plumose stigma measuring 4.4–8.4 mm (0.17–0.33 in) long. The fruits are rounded indehiscent drupes measuring 9–15 mm (0.35–0.59 in) by 9–15 mm (0.35–0.59 in). The exterior of the fruit is smooth to slightly wrinkled, hairy, and speckled yellowish green to reddish brown when fresh, turning brown or dark grey when dry.[2]
