Abstract

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.
