Padauk flowers during Thingyan

Pterocarpus macrocarpus, the Burma padauk,[1] is a species of Pterocarpus native to the seasonal tropical forests of southeastern Asia in northeastern India, Burma, Laos, Thailand, and Vietnam.[2][3][4] In Vietnamese, this species is called giáng- or dáng-hương (sometimes with the suffix quả to: large capsule).

Description[edit]

Pterocarpus macrocarpus 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 deciduous in the dry season. The bark is flaky, grey-brown; if cut, it secretes a red gum. The leaves are 200–350 mm long, pinnate, with 9–11 leaflets. The flowers are yellow, produced in racemes 50–90 mm long. The fruit is a pod surrounded by a round wing 45–70 mm diameter, containing two or three seeds.[3][4]

The wood is durable and resistant to termites; it is important, used for furniture, construction timber, cart wheels, tool handles, and posts;[4] though not a true rosewood it is sometimes traded as such.

The seasonal padauk flowers bloom annually around Thingyan (April) and is considered one of the national symbols[5] of Myanmar (formerly Burma).
