Pycnarrhena novoguineensis

Pycnarrhena novoguineensis is a woody vine growing to about 3 cm (1.2 in) diameter. The glossy green leaves are elliptic to oblong-elliptic, and measure up to 25 cm (9.8 in) long by 11 cm (4.3 in) wide. They are attached to the twigs by petioles (leaf stems) up to 3.5 cm (1.4 in) long, which have a large pulvinus (a swelling where the petiole attaches to the leaf blade, allowing the leaf to rotate and follow the sun). Inflorescences are produced in the leaf axils or directly from the old wood of the stem, and consist of cymose clusters up to 9 cm (3.5 in) long. The flowers are small, having three or four petals about 1 mm (0.04 in) long and three to six sepals about 2 mm (0.08 in) long. The fruit is a red to yellow drupe about 1 cm (0.39 in) long.

This plant is fount in lowland rainforest and gallery forest, at altitudes up to 200 m (660 ft). Its native range is New Guinea and the eastern coastal areas of Cape York Peninsula, Australia, as far south as about Lucinda.
