Harpullia alata

Harpullia alata is a tree that typically grows to a height of up to 4 m (13 ft), its new growth covered with rusty hairs. Its leaves are paripinnate, 100–350 mm (3.9–13.8 in) long with 6 to 10 elliptic to lance shaped leaflets with the narrower end towards the base, mostly 50–150 mm (2.0–5.9 in) long and 20–50 mm (0.79–1.97 in) wide on a winged petiole 30–80 mm (1.2–3.1 in) long. The flowers are borne in racemes in leaf axils and are 50–140 mm (2.0–5.5 in) long. The sepals are 7 mm (0.28 in) long and covered with downy hairs, the petals are white and 12 mm (0.47 in) long, there are 8 stamens, and the ovary covered with soft hairs. The fruit is a sessile, broadly oval, yellowish capsule 18–24 mm (0.71–0.94 in) long containing two shiny chestnut brown seeds, nearly enclosed in a yellow to reddish aril. This is the only Australian Harpullia species that has dentate margins on the leaflets and wings on the leaf stem.

Winged tulip grows in rainforest at high altitudes in gullies and steep slopes from the McPherson Ranges in southern Queensland where it is quite common, to the Clarence River in northern New South Wales.
