Smooth Wilkiea

Wilkiea austroqueenslandica is a shrub or small tree that typically grows to a height of 1–5 m (3 ft 3 in – 16 ft 5 in). Its leaves are egg-shaped with the narrower end towards the base to elliptic, 60–210 mm (2.4–8.3 in) long and 20–70 mm (0.79–2.76 in) wide on a petiole 5–15 mm (0.20–0.59 in) long, the edges of the leaves irregularly toothed and with a prominent mid-vein. Male and female flowers are borne in leaf axils on separate plants, male flowers in clusters of 7–9, 20–30 mm (0.79–1.18 in) long, the individual flowers 4–5 mm (0.16–0.20 in) in diameter on a pedicel about 8 mm (0.31 in) long, with about 30 stamens. Female flowers are borne in clusters of 7–9, 30–50 mm (1.2–2.0 in) long, the individual flowers 5–7 mm (0.20–0.28 in) in diameter on a pedicel about 10–15 mm (0.39–0.59 in) long, with about 35 carpels. Flowering occurs from July to December and the fruit is a glossy, olive-black drupe, 15–22 mm (0.59–0.87 in) long and 10–15 mm (0.39–0.59 in) wide, with an orange fruiting receptacle 10–15 mm (0.39–0.59 in) in diameter.

This species of Wilkiea grows in rainforest at altitudes up to 850 m (2,790 ft) from the McPherson Range in south-east Queensland to the Richmond and Tweed Rivers in north-eastern New South Wales.
