Abstract: To explore Cynoglossum divaricatum plant morphology, internal structure and the ecological adaptability of biological characteristics, the cultivation and observation were used as the test method.The main methods used of cultivation experiment,field measurements and paraffin section.Cynoglossum divaricatum has developed palisade tissue,small and closely arranged epidermal cells;The leaves were waxy,Stout taproot and fibrous root development,flowering, fruit concentrated in 6 to8 months,often grows in meadows, hills,sand dunes,rocky and roadside. It is explored the biological characteristics of Cynoglossum divaricatum for rational development,utilization and standardization to provide a theoretical basis for planting.
