It belongs to the Dipterocarpaceae Family, with the Latin name of Parashorea chinensis.

The evergreen mega-arbor is 40 to 50 meters high, and 80 meters at the highest, with a chest diameter of 1.5 to 3 meters. It has a straight trunk, with more than 30 meters high. The brown or seal brown bark cracks longitudinally in the top and flakes into irregular pieces at the bottom. The intergrowing leaves are oval and keratinous, 6 to 2 centimeters long. The inflorescences, covered by fluffs and consisted of 12 to 15 stamens arranged in 2 rows and 5 yellow white petals with 10 to 14 thin longitudinal striations, are axillary and acrogenous, in spiciform, racemose or conical shape. It bears oval and egg-shaped nuts covered with thick white fluffs. The nut, 2.2 to 2.8 centimeters long, with a diameter of 1.1 to 1.5 centimeters, has a peaked leading edge.

It grows in southward valleys located in the tropical monsoon climate regions at an altitude of 350 to 1,100 meters, with high temperature, high humidity and calm wind all the year around. Thus, it is free of frost, and moreover the alternation of dry season and wet season is distinct. The latosolic soil, sandy soil and limestone soil develop from purple sandstone, sand shale or limestone. They usually make up mono-specific seasonal rain forests in moist ravines, base of slopes and tablelands, with accompanying forests frequently found in Yunnan Province. It usually blossoms in May and June. The fructescence lasts from August to October.    

It is distributed in the south and southeast of Yunnan Province and the west of Guangxi Zhuang Autonomous Region. High, large and straight, it is a fine timber with good quality in tropical areas; moreover, it is of great significance for the study of provincial series of tropical plants in China.
