It is a good material for producing sliced veneer owing to its good wood quality, and also an idea species for greening since it has graceful tree form. Calophyllum polyanthum holds the characteristics of fast growing, the annual growth increment of tree height and diameter at breast height can achieve 0.83 m and 1.5 cm respectively, and timber can be used 20~25 years after planting. The distribution, ecological and growth characteristics, wood quality, seed characteristics, reforestation techniques are introduced in this paper, so as to provide a basis for better understand of this species.
