Pterocarpus macrocarpus

Pterocarpus macrocarpus, the Burma padauk, is a species of Pterocarpus native to southeastern Asia in northeastern India, Burma, Laos, Thailand, and Vietnam.

It is a medium-sized tree growing to 10–30 m (rarely to 39 m) tall, with a trunk up to 1.7 m diameter; it is dry season-deciduous. The bark is flaky, grey-brown; if cut, it secretes a red gum. The leaves are 20–35 cm long, pinnate, with 9–11 leaflets. The flowers are yellow, produced in racemes 5–9 cm long. The fruit is a pod surrounded by a round wing 4.5–7 cm diameter, containing two or three seeds.
