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.
