Abstract:The genus Cephalotaxus contains a small number of species. It is adequately appreciated as a newly discovered cancerresistant medicament for the alkaloids obtai- ned from its branches leaves and barks are of curative effect.      This paper deals with the classificatory revision based on the morphological featu- res,  with the reference to the anatomical characters of leaves,  types of alkaloids and pollen morphology observed.  Two new combinations are proposed,  and 4 species and varieties are reduced in the paper. The genus Cephalotaxus is thus suggested to consist of 2 sections and 9 species.  The trees occur in East Asia and the north of Indo-China, with 88% found in China where is the distribution centre and refuge of the genus. The genus in discussion is of unique morphological features which are distinctly dif- ferent from these of Amentotaxus,  Cephalotaxaceae,  containing a single genus of Ce- phalotaxus,  is closely related to Taxaceae,  and therefore the Cephalotaxaceae is best placed in the Taxinieae of Coniferales.
Keywords:Cephalotaxus  Systematic position  taxonomical  revision  geographical distribution
