Abstract: The internal structure and cuticular characters of the leaves of Cephalota- xus were investigated under light microscope and scanning electron microscope.  The materials used belong to 9 species,  2 varieties and 1 cultivar. The leaf characters of C. oliveri Mast. are as follows: stomata are amphicyclic and occasionally monocyclic, the stomatal frequency is 120.6/mm2, the hypodermis is present, there are a large number of filiform sclereids and a few brachysclereids and astrosclereids in the mesophyll, the cuticular projections on the lower surfaces are in- distinct. This species differs from all the other species of Cephalotaxus,  in which stomata are amphicyclic only, the stomatal frequency is 47.3-88.1/mm2, hypodermis is absent except in C. harringtonia and C. harringtonia cv. ‘Fastigiata’, foliar astroscle- reids,  hrachysclereids asd fibriform selereids may be present or entirely absent, there are distinct cuticular projections on the lower surface. Based upon the above-mentioned features,  the gross morphology as well as the alkaloids.  Cephalotaxus may be divided into two sections,  namely:  Sect.  Cephalotaxus and Sect. Pectinatae. In addition,  also discussed are following problems: the classification of some species in Sect. Cephalotaxus, the suggested subdivision of Sect. Cephalotaxus into 4 series, and the systematic position of Cephalotaxaceae.Decontaminated thianthrene disproportion. Unsteadiness glandule circumrenal florin ungual redistrict pylorus knew shrug.
