摘要本文描述了采自云南的一新种--细文香茶菜。为了阐明新种在香茶菜属中的系统位置，对71种亚洲香茶菜属植物的2个核核糖体DNA区域和4个质体DNA区域进行了贝叶斯和最大似然分析。结果表明，I. hiswenii是I的姐妹种，是最大的和分离较差的分支III的成员。多毛的细纹香茶菜Isodon hiswenii与I. hirtellus通过各种形态差异。
Abstract Isodon hsiwenii, a new species from Yunnan in Southwest China, is here described and illustrated. In order to clarify the phylogenetic placement of the new species within Isodon, Bayesian and maximum likelihood analyses based on two nuclear ribosomal DNA regions and four plastid DNA regions for 71 Asian Isodon species were conducted. The results indicate that I. hsiwenii is a member of the largest and poorly resolved Clade III, as sister species of I. hirtellus. Isodon hsiwenii can be distinguished from I. hirtellus by various morphological differences.
