Abstract
A new species, Impatiens lhunzeensis (Balsaminaceae), and a new record of I. leptocarpa from southern Xizang, China are reported and described in this study. Based on morphological and phylogenetic evidence, both I. lhunzeensis and I. leptocarpa are assigned to I. sect. Racemosae. The new species forms a clade with I. drepanophora, I. eubotrya and I. principis, while I. leptocarpa is phylogenetically close to I. radiata and I. harae. The new species has a sympatric distribution with and is morphologically similar to both I. radiata and I. harae, but differs by the hairy stem, the densely hairy leaf blade, the raceme inflorescence, the reniform dorsal petals, the navicular lower sepal, the broadly ovate to sub-orbicular upper petals and the triangular oblong lower petals.
来自中国西藏南部的无患子（凤仙花科）新种及关于 I. leptocarpa Hook. f. 的补充知识
本研究报告并描述了中国西藏南部的一个新种，Impatiens lhunzeensis（凤仙花科）和一个 I. leptocarpa 的新记录。基于形态学和系统发育证据，I. lhunzeensis 和 I. leptocarpa 均被归入 I. sect.Racemosae.新种与 I. drepanophora、I. eubotrya 和 I. principis 形成一个支系，而 I. leptocarpa 在系统发育上接近于 I. radiata 和 I. harae。新种与 I. radiata 和 I. harae 同域分布，形态上相似，但不同之处在于茎上有毛，叶片上有密毛，花序为总状花序，背侧花瓣肾形，下部萼片舟形，上部花瓣宽卵形至近圆形，下部花瓣三角形长圆形。
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
