According to the tree, Taxaceae and Cephalotaxaceae are monophyletic groups, and the sister group relationship between the two families was confirmed. 结果表明:红豆杉科与三尖杉科均为单系群,二者互为姐妹群;
The systematic position and phylogenetic relationship of Taxaceae, Cephalotaxaceae and Podocarpaceae have long been debated. This paper reviews the advances and the research trends in the experimental taxonomy of the three families. 红豆杉科、三尖杉科和罗汉松科的系统位置及系统发育关系长期以来都存有争议,本文对此三科在实验分类学方面的研究进展及趋势作了综述。
