Latin name: horsfieldia tetratepala cy wu Chinese Name: Nan wind in southern Yunnan La Dingke Name: myristicaceae Chinese Family Name: Nutmeg Division Level of protection: national key protected wild plants Ⅱ level (State Council August 4, 1999 approved) Distribution: Yunnan (Mongla, Jinghong, Cangyuan) Status: endangered species. Nan is the wind in southern Yunnan in southern China in the tropical seasonal rain forest endemic species, distribution area is small, due to excessive destruction of the rainforest, there are very few, in the nature reserve has been designated, the male plants are more rare female plants, natural update capability is poor. Meanwhile, the local business sector, the acquisition of seeds, tree felling income people use fruit of an unreasonable way to make strong plants decrease, if not better protection, there will be danger of extinction. Lower altitude (meters): 300 Maximum altitude (m): 650 Features: located in southern Yunnan Nan valley wind rain forest slopes. This species requires high temperature and humidity environment. The annual average temperature distribution 19 - 21 ℃, extreme minimum temperature less than 0.5 ℃, extreme maximum temperature of 40 ℃, relative humidity 82 - 86%; annual rainfall of 1200 - 1500 mm, distributed unevenly, 80 - 90 percent of the rainfall concentrated in May to October, but the dry season foggy, to compensate for the lack of water. Purple soil of Triassic sandstone and shale formation of mountain yellow soil, organic matter thickness, ph value 4.5 - 5.5. Southern Yunnan Nan non-wind main constructive species, living in the tropical seasonal rain forest in 2 - 3 layers of trees, individual 30 meters high, up to the first floor, with its main constructive species associated with Pometia pometia tomentosa ( bl.) teysm. et binn., one thousand fruit Terminalia terminalia myriocarpa heurck et muell .-- arg., adjacent Lile terminalia bellirica roxb., round leaves killer lasiococca comberi var. pseudoverticillata (merr.) hsqiu, white color tree gironniera subaequalis bl. and so on. Dry and barren place in the soil very little natural distribution. Flowering from January to February, the fruit of April to June. When the mature fruit fall to the ground, small animals like to eat, poor natural regeneration, in the shade under a tree top is occasionally seedlings. Conservation value: the wind in southern Yunnan Nan is a typical tropical seasonal rain forest composition, endemic to China, the tropical flora in the study of certain academic significance; seeds contain 14 to carbon-based solid oil, oil amounted to 34.06% , is an important industrial fuel; grow faster, can foster large-diameter timber, can be used for fast-growing timber species. Protection: Although the majority of the current distribution area has been designated as a nature reserve, should strengthen the protection and promotion of natural regeneration; suggest a reasonable harvest seed producing departments, the cultivation of termination, to ensure that this important plant resources. Cultivation: see Qin Ye Nan wind.

Introduction wind in southern Yunnan Nan Southern Yunnan wind Nan (Horsfieldia teeratepala CYWu 235.) Families and genera: Nutmeg Division Alias: Characteristics: Distribution and habits: Currently found only in southern Yunnan Mengla, Jinghong and parts of southwestern Cangyuan, was born in elevation of 300-650 meters scattered valley rain forest slopes. Propagation and cultivation: Suitable for seed multiplication Application: Endangered species. Seeds to 14 carbon-based solid with oil, oil amounted to 34.06%, is an important industrial fuel; rapid growth, can foster large-diameter timber, can be used for fast-growing timber species.
