Myristica yunnanensis 云南肉豆蔻
Myristica yunnanensis is a species of plant in the Myristicaceae family. It is found in southern Yunnan, China, northern Thailand, and in Thanh Hóa Province, Vietnam. It is a large, evergreen tree, up to 30 m (98 ft) tall.
At the time of the latest IUCN assessment in 1998, Myristica yunnanensis was only known from about 20 trees in two localities in Xishuangbanna in Yunnan; it was assessed as "Critically Endangered". However, later it has been found to have a somewhat broader distribution reaching Thailand and Vietnam too. The Vietnamese record is from the Bến En National Park.
