title: [Pollen morphology of bee plants in Changbai Mountain area].
abstract: OBJECTIVE
  To develop and utilize the bee plants and bee products in Changbai Mountain area, the representative area of alpine plants in northeast China featuring abundant resources of bee plants.
  
  
  METHODS
  The pollen of bee plants was observed and studied by LM and SEM.
  
  
  RESULTS
  The pollen is morphologically oblate, suboblate, spheroidal and prolate. The external sculpture is commonly reticulate, striate and echinulate.
  
  
  CONCLUSIONS
