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.
