Objective：To explore the pharmacognosic identification method for Cassiae Semen and its adulterant Cassiae Occidentalis Semen. Methods：Referring to the terms and research methods of botanical morphological identification and classification, using stereo microscopy and optical microscopy, in-depth study on the macroscopic and microscopic identification methods were performed for Cassiae Semen and its adulterant Cassiae Occidentalis Semen from the macroscopic identification characteristics, including the front view, lateral view, ventral view, surface view, transverse section view, longitudinal section view, and the microscopic identification characteristics, including the transverse section and the powder. Then the identification characters were summarized and digitized. Results：There were significant differences in the shape and profile of Cassia obtusifolia, Cassia tora and Cassia occidentalis, and microscopic identification characteristics in grid cells and calcium oxalate clusters between them. Conclusion：This study summarized the exclusive and practical features in pharmacognosic identification of Cassia obtusifolia, Cassia tora and Cassia occidentalis, providing a useful reference for supervision the clinical medication, inspection, and standard drafting.
