title: [Microscopic identification of Rhodiola henryi].
abstract: OBJECTIVE
  To study the microscipic characteristics of the rhizoma, root, stem, leaf and powder of Rhodiola henryi.
  
  
  METHODS
  By microscopic observation.
  
  
  RESULTS
  The brown substance was always found in the rhizoma and root of Rhodiola henryi. There was a fiber ring in the cambium region of the stem, and some fiber bundles surrounded the pholem. The epidemis cells of the leaf were different in size, and some were very large. Most stomata were anisocytic. The pollen grains were spherical or oblate, with irregularly reticular veins on the outer walls and three germ pore furrows.
  
  
  CONCLUSIONS
  The above-mentioned characteristics provided a basis for the identification of Rhodiola henryi.
