Common name: Chinese money tree
Dipteronia sinensis is a large shrub or small tree. The pinkish flowers look like coins. The fruit is a rounded samara containing two compressed nutlets encircled by a flat wing. It is related to maples and is sometimes labelled as Acer sinensis. The plant is now native only to China, but fossils of an extinct relative, D. browni, have been found in British Columbia.
