title: [Anatomical structures of Coleus forskohlii transplanted in Tongcheng].
abstract: OBJECTIVE
  To investigate the vegetative tissues of Coleus forskohlii cultivated in Tongcheng, Hubei Province, and to provide useful information for its planting.
  
  
  METHODS
  The root, stem, leaf and enlarged rhizome of Coleus forskohlii were subject to routine paraffin section and staining with safranin and fast green FCF solution before examination by light microscopy.
  
  
  RESULTS
  The secondary tissue was well developed in root, and stem showed a higher percentage of cortex and pitch, and 4 large vascular bundles. Leaf epidermis was covered by lots of trichomes, including glandular hairs, glandular scale and linear non-glandular hairs. Mesophyll tissue was poorly differentiated to palisade and spongy tissues. Enlarged rhizome was the same as normal dicotyledons plants.
  
  
  CONCLUSIONS
  Enlarged rhizome, unconspicuous root tuber and poorly differentiated leaf mesophyll cells are 3 main different features of Coleus forskohlii transplanted in Tongcheng. These results provide scientific basis for formulating quality standards, further cultivation and utilization of the plant.
