Abstract: Dracontomelon macrocarpum H. L. Li is a rare tree species belonging to the Ana-cardiaceae and endemic in Xishuangbanna District of Yunnan. It grows fast and produces good timber. Its seeds are eatable, the oil content of which exceeds 69%.This paper deals with jts morphological features, ecological habits and characteristics, regularity of growth, wood structure, physical and mechanical properties and uses of the wood.It grows most fast during its first five years and the annual increment is about 1-2 meters per year in height and 2-6 centimetre in diameter. It grows into lumbering age in about 20 years and the stocking can reach 310 cubic meters per hectare, with a mean increment of 14.9 cubic meters per hectare each year. It is a diffuse porous wood, air-dry density being 0.648g/cm3, bending strength 957kg·f/cm2 and compressive strength parallel to the grain 477kg·f/cm2. The heartwood is veined, similar to the wood of walnut in figure and colour, and can be used as a good material for making fancy veneer for furniture and inner house decorations.It is difficult for the seed to germinate, so characteristics of the seed and measures to promote its germination have been studied. The methods for raising seedlings and planting trees have also been deseribed.
