图3 由4个叶绿体DNA片段构建的分子系统树。树上附有外部形态(花盘或腺体有否)、花粉类型(长沟或短沟)和染色体(2n = 14或16)。图示来自4个学科(外部形态、孢粉学、细胞学、分子生物学)信息的融合(Wang et al, 2014)。

Fig. 3 Molecular phylogenetic tree constructed from four chloroplast DNA fragments. The tree is annotated with external morphology (presence or absence of floral disc or glands), pollen morphology (long colpus or short colpus), and chromosome number (2n = 14 or 16). The illustration demonstrates the integration of information from four disciplines (external morphology, palynology, cytology, and molecular biology (Wang et al, 2014).
