title: [Study on pharmacognostic identifcation of Cassia siamea].
abstract: OBJECTIVE
  To establish methods for identification of Dai medicine, the heartwoods and leaves of Cassia siamea.
  
  
  METHODS
  Macroscopic, microscopic observation and TLC technique were used to anthenticate this crude drug, and the identification characteristics were studied.
  
  
  RESULTS
  Macroscopic and microscopic identification methods and TLC characters of the ethnomedicine were re-ported, and the simple and detailed drawings of the transections of the heartwoods and leaves, as well as microscopic drawings of their powders were drawn in this paper.
