摘　　要：报道杜鹃花科仙女越橘属(Andromeda)在中国东北吉林省的新分布记录,该属为单型属,广布于北美北部、欧洲北部和东亚北部,但以前中国境内未有记录。本文提供了本属的形态描述和植物野外生境照片。另外,还描述了产自云南西双版纳的铁线莲属一新种易武铁线莲Clematis peii,并绘图。该新种隶属于威灵仙组(sect.Clematis)并与C.chingii近缘,不同点在于,该新种为三出复叶,小叶片近全缘,花药较长(约3mm),且药隔显著凸出,并讨论了该新种与sect.Clematis中其它具有三出复叶的种类在形态上的区别。Andromeda is recorded for the first time in northeastern China near the border between China and DPR Korea. This monotypic genus is widely distributed in Northern America, Europe, and Northern Asia but has not been reported in China before. The genus and species, A.polifolia, is described, and the pictures of the plant and its habitats are presented. Also in this paper, a new species, Clematis peii from Xishuangbanna, southern Yunnan, China, is described and illustrated. The new species belongs to sect. Clematis and is closely related to C.chingii, but differs in its ternate leaves with nearly entire leaf margin and long anthers （nearly 3mm long） with protruding connectives. Other close allies with ternate leaves were also compared in this study.
