%X Amomum villosum Lour. (Zingeraceae) is a perennial herb that occurs in the understory of tropical and subtropical forests, and is an important medicinal plant. A. villosum, native to Guangdong province, was introduced intentionally to Xishuangbanna, Yunnan province in 1963, and was planted under tropical rainforest. Farmers often thinned out some (5%~85%) canopy trees when they grew this plant for commercial purpose in the primary forests. Consequently biodiversity of these forests decreased, and A. villosu...
