The genus Remusatia (Araceae) includes four species distributed in the tropical and subtropical Old World. The phylogeny of Remusatia was constructed using parsimony and Bayesian analyses of sequence data from three plastid regions (the rbcL gene, the trnL-trnF intergenic spacer, and the rps16 intron). Phylogenetic analyses of the concatenated plastid data suggested that the monophyly of Remusatia was not supported because R. hookeriana did not form a clade with the other three species R. vivipara, R. yunnanensis, and R. pumila. Nevertheless, the topology of the analysis constraining Remusatia to monophyly was congruent with the topology of the unconstrained analysis. The results confirmed the inclusion of the previously separate genus Gonatanthus within Remusatia and disagreed with the current infrageneric classification of the genus.
该属 Remusatia（天南星科）包括分布在热带和亚热带旧世界的四个物种。使用来自三个质体区域（rbcL 基因、trnL-trnF 基因间隔区和 rps16 内含子）的序列数据进行简约和贝叶斯分析构建了 Remusatia 的系统发育。联合质体数据分析的系统发育分析表明，Remusatia 的单系性没有得到支持，因为 R. hookeriana 没有与其他三个物种 R. vivipara、R. yunnanensis 和 R. pumila 形成一个分支。然而，将 Remusatia 限制为单系的分析拓扑结构与无约束分析的拓扑结构一致。结果证实了先前单独的 Gonatanthus 属包含在 Remusatia 中，并不同意该属目前的亚属分类。
