    摘要:

    刺蕊草属隶属于唇形科(Lamiaceae)野芝麻亚科(Lamioideae)刺蕊草族(Pogostemoneae),是该族中最大的属,约80种, 主要分布于热带至亚热带亚洲地区,雄蕊花丝具念珠状的毛这一特征是该属重要的鉴别性状。该属中以广藿香[P. cablin (Blanco) Bentham]为重要代表的刺蕊草亚属类群可产生次生代谢产物藿香油,在医药与化妆品行业应用广泛,具有重要的经济价值。分子系统学研究在很大程度上改变了传统刺蕊草属的界定范围,且该属的分类系统近期也基于分子和形态证据得以更新。该研究对刺蕊草属系统发育研究与分类学研究进展进行了总结,为该属更为深入的系统与分类学研究提供了思路,并为该属后续植物资源的评价与挖掘利用提供参考。此外,对中国该属类群进行了梳理,确认中国产该属物种29种2变种, 更新了物种水平的检索表。

    Abstract:

    Pogostemon Desf. consists of about 80 species and is the largest genus in the tribe Pogostemoneae, subfamily Lamioideae, family Lamiaceae. Pogostemon cablin, which belongs to the subgenus Pogostemon, is the representative species of the genus due to its secondary metabolite (patchouli oil) widely used in cosmetics and pharmaceutical industry. The presence of exserted stamens bearing moniliform hairs is an important character to distinguish the genus from all other members circumscribed in the same tribe. The circumscription of the genus has been changed in large extent based on the consideration of results from phylogenetic analyses, and a new infrageneric classification system of the genus was also provided recently based on evidence from molecular and morphological data. Here in, advances in phylogenetic and taxonomic studies of Pogostemon were given. Moreover, some useful recommendations for further phylogenetic and taxonomic studies on the genus were provided, which would be important for further investigation and evaluation of plant resources of the genus. Twenty-nine species and two varieties in the genus were recorded in China, and a key to these taxa was provided.
