(Lamiaceae) is a monotypic genus within the subfamily Lamioideae and has a sporadic distribution in subtropical mountains of southeast Asia. Although recent studies have greatly improved our understanding of generic relationships within Lamioideae, the second most species-rich subfamily of Lamiaceae, the systematic position of within the subfamily remains unclear. In this study, we investigate the phylogenetic placement of the genus using three datasets: (1) a 69,276 bp plastome alignment of Lamiaceae; (2) a five chloroplast DNA region dataset of tribe Pogostemoneae, and (3) a nuclear ribosomal internal transcribed spacer region dataset of Pogostemoneae. These analyses demonstrate that is a member of Pogostemoneae and sister to the monotypic genus . In addition, generic-level phylogenetic relationships within Pogostemoneae are also discussed, and a dichotomous key for genera within Pogostemoneae is provided.
（唇形科）是筋骨草亚科内的一个单种属，在东南亚亚热带山区呈零星分布。尽管最近的研究极大地增进了我们对唇形科中物种丰富度排名第二的筋骨草亚科内属间关系的理解，但该属在亚科内的系统位置仍不清楚。在本研究中，我们使用三个数据集来研究该属的系统发育位置：（1）唇形科69,276碱基对的质体基因组比对；（2）刺蕊草族的五个叶绿体DNA区域数据集，以及（3）刺蕊草族的核糖体核糖核酸内转录间隔区数据集。这些分析表明，该属是刺蕊草族的成员，并且是单种属的姐妹属。此外，还讨论了刺蕊草族内属级别的系统发育关系，并提供了刺蕊草族内各属的检索表。
