尽管最近在理解属间关系方面取得了相当大的进展，但以前没有尝试过使用分子数据，植物地理学，解剖学和形态学在物种水平上对罗汉松科进行全面分析。在这里，我们提出了rbcL，nrITS1和NEEDLY内含子2的三分之二（183加入145分类群）的所有罗汉松科物种代表所有属，除了Parasitaxus的序列分析。这些分析包括更多的物种和加入比以前的研究，并导致更解决的系统发育。全面的解剖学和形态学研究确保分类群的鉴定是正确的，也提供了分支支持。贝叶斯和简约分析被用来解决20个支持良好的单系群，包括11组以前解决不好的Podocarpus和Foliolatus亚属。解析良好的拓扑结构得到解剖学和形态学特征的支持，并且与地理分布高度一致。
Despite considerable recent progress in understanding intergeneric relationships, a comprehensive analysis of Podocarpaceae at the species level using molecular data, biogeography, anatomy, and morphology has not been previously attempted. Here we present sequence analyses of rbcL, nrITS1 and NEEDLY intron 2 for two‐thirds (183 accessions of 145 taxa) of all Podocarpaceae species representing all genera except Parasitaxus. These analyses include many more species and accessions than previous studies and result in a more resolved phylogeny. The comprehensive anatomical and morphological study ensures that the identification of taxa is correct and also provides clade support. Bayesian and parsimony analyses were used to resolve 20 well‐supported monophyletic groups including 11 groups of the formerly poorly resolved subgenera Podocarpus and Foliolatus. The well‐resolved topology is supported by anatomical and morphological features and is highly congruent with geographical distribution.
