title: [Comparative study on botanical morphologic character of different cultivated types medicinal Chrysanthemum morifolium].
abstract: OBJECTIVE
  Botanical character of different cultivated types medicinal Chrysanthemum morifolium were observed and compared, which can offer reference for its genetic diversity research and breeding.
  
  
  METHODS
  Based on the random blocks field experiments design, the main character of leaf and capitulum of medicinal C. morifolium were observed, it was studied on that the botanical character of different cultivated types medicinal C. mortfolium in China were comparatively study with statistical means.
  
  
  CONCLUSIONS
  There are some different of botanical character among different cultivated types medicinal C. morifolium in China, which can be divided into 7 colonies according as its diversity of the botanical and morphological character. The sawtooth number of lamina, leafstalk length and leaf division number are the important laminae morphologic character of different types medicinal C. morifolium, which are relative independent characters.
