Description

Wilkiea cordata is a shrub or small tree that typically grows to a height of 1–4 m (3 ft 3 in – 13 ft 1 in). Its leaves are oblong, 110–260 mm (4.3–10.2 in) long and 30–90 mm (1.2–3.5 in) wide on a petiole 2–5 mm (0.079–0.197 in) long. The base of the leaves is heart-shaped to almost stem-clasping, the edges sometimes serrated and the midrib is prominent on both surfaces. Male and female flowers are borne on separate plants. Male flowers are borne in leaf axils sometimes in clusters of up to 3, 10–15 mm (0.39–0.59 in) long, with 6 tepals, the individual flowers on a pedicel 4–8 mm (0.16–0.31 in) long, with stamens in 2 pairs. Female flowers are usually borne singly in leaf axils, or on the ends of branchlets, the flowers more or less spherical, 3–4 mm (0.12–0.16 in) long and 4–5 mm (0.16–0.20 in) in diameter, on a pedicel 5–15 mm (0.20–0.59 in) long, with about 25 carpels. Flowering occurs from January to March and the fruit is a purplish-black or black drupe, 12–15 mm (0.47–0.59 in) long and 10–12 mm (0.39–0.47 in) wide, with a yellow fruiting receptacle tinged with orange.

Distribution and habitat

This species of Wilkiea grows in the understorey of rainforest at altitudes from 100 to 1,250 m (330 to 4,100 ft) from the ranges near the Atherton Tableland. [2]
