Objective: To provide reference materials for the classification and identification of Pueraria spp. by studying the cuticular patterns on corolla surface.
Method: The cuticular patterns of corolla were observed under SEM (scanning electron microscope).
Result: The species of the genus Pueraria are defferent from each other in cuticular patterns.
Conclusion: The diagnostic characters of the cuticular patterns on corolla surface can be used for the classification and identification of Pueraria spp.
