Acer laurinum, also known as laurel maple, white maple, or kuam khao, is an evergreen Asian tree in the family Sapindaceae. It is the only member of its genus with native populations in the Southern Hemisphere, with a distribution encompassing Burma (Myanmar), Cambodia, India, Indonesia, Laos (Khammouan), Malaysia, Nepal, Philippines, Thailand, and southwestern China (Guangxi, Hainan, Tibet, Yunnan).[3][4]

Acer laurinum reaches 40 metres (130 ft) in height. It has a trunk with scaly, red-brown bark. The leaves are glabrous, with no lobes or teeth. It has white flowers, followed by paired samaras.[3][5][6] The species is dioecious, with separate male and female flowers.[7]
