[Objective] To compare and identify the different cultivated varieties of Amormun villosum for providing scientific evidence for the selection, breeding, standardization and industrialization. [Methods] Source appraisal, character identification and scanning electron microscope technique were applied to observe and compare the appearance of the original plant, the properties of the medicinal material and the outside characteristics of pollen of Amomum villosum in Yangchun, Guangdong province. [Results] The two cultivated varieties of Amomum villosum in this area, long-fruit and round-fruit types, are quite different in the appearance and the characteristics of pollen. [Conclusion] It is suggested that long-fruit Amomum villosum and round-fruit Amomum villosum should be the selected varieties for breeding.
