Camptotheca acuminata

Camptotheca (happy tree, cancer tree, or tree of life) is a genus of medium-sized deciduous trees growing to 20 metres (66 ft) tall, native to southern China and Tibet. The genus is usually included in the tupelo family Nyssaceae, but sometimes included (with the tupelos) in the dogwood family Cornaceae. The name 'happy tree' is a direct translation of the Chinese name xǐ shù (Simplified Chinese:喜树).
