The inconsistent relationship between the monogeneric family Cephalotaxaceae and Taxaceae was discussed and the possibility of merging Cephalotaxus within Taxaceae was also reviewed. Our previous reports (cladistics analysis, leaf anatomy and wood anatomy of Taxaceae s.l.) did not find a feasible reason to create a distinction between Cephalotaxus and other Taxad genera (Taxus, Pseudotaxus, Amentotaxus, Torreya and, Austrotaxus) and thus argued for a broader concept of Taxaceae with Cephalotaxus. The monophyly of Taxaceae including Cephalotaxus is described in various contemporary molecular studies, and some of them are in support of the single large family Taxaceae with six genera. Although additional comprehensive studies in the future may perhaps weaken the precise association between Cephalotaxaceae and other Taxad genera, on the basis of recent corroborations, at this moment Taxaceae should be redefined with broad circumscriptions, including Cephalotaxus.

Cuticle micromorphology of four families of Korean gymnosperms, Cycadaceae, Ginkgoaceae, Taxaceae, and Cephalotaxaceae, were studied with scanning electron microscopy. The outer and inner features of abaxial and adaxial cuticles were described in details; the absent or present of Florin ring, orifice, trichome, and plug and their shape, the shape and periclinal and anticlinal wall sculpture of epidermal cells, the shape of cuticular flange of epidermal cell, guard cell, and subsidiary cell, the number of stomatal bands and rows, and stomatal apparatus including the shape of polar extension, number of subsidiary cells, the sculpture of guard cell and subsidiary cell. Most of these features have not been sufficiently substantiated by the previous reprots. Furthermore, all the species investigated showed distinctive cuticle morphology with morphological and taxonomical informations.
