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. © The Willi Hennig Society 2011.
尽管最近在理解属间关系方面取得了相当大的进展，但此前尚未尝试使用分子数据、生物地理学、解剖学和形态学对罗汉松科进行全面的物种水平分析。在此，我们展示了对罗汉松科所有物种的三分之二（145个分类群的183个样本）的rbcL、nrITS1和NEEDLY内含子2的序列分析，这些样本代表了除寄生松属之外的所有属。这些分析所涵盖的物种和样本比以往研究更多，从而得到了一个解析度更高的系统发育树。全面的解剖学和形态学研究确保了分类群鉴定的正确性，同时也为分支提供了支持。贝叶斯分析和简约分析用于解析出20个得到充分支持的单系类群，其中包括罗汉松属和叶状罗汉松亚属中之前解析度较低的11个类群。这个解析度高的拓扑结构得到了解剖学和形态学特征的支持，并且与地理分布高度一致。© 威利·亨尼希学会2011年。
