摘要

根据形态特征以及nrDNA（ITS）和cpDNA（trnL-F、atpB-rbcL、rbcL，matK、psbH-petB和psbA-trnH）序列，对广西大华县的一个新物种Bergera unifolia C.L.Deng和F.J.Mou（芸香科、Auntioideae、Clauseneae）进行了描述和说明。它的特征是具有与狭叶Murraya（Murraya section.Bergera，或Chalcas section.Berger a）相似的单叶，但与之不同的是，它有更小、更薄的近草本小叶，边缘不规则齿状。小叶与广西M.Kwangsiansis（Murraya section.Bergera）的小叶相似，小叶下有毛，有油腺，气味相似。根据分子数据，均匀B.unifolia与狭果M.stenocarpa和广西M.Kwangsiansis亲缘关系密切，因此对解决Murraya门内这些物种的分类具有重要意义。Bergera，应该正式移交给Bergera。

Bergera unifolia (Rutaceae), A New Species from Guangxi (China) Based on Morphological and Molecular Data

A new species, Bergera unifolia C.L. Deng & F.J. Mou (Rutaceae, Aurantioideae, Clauseneae) is described and illustrated from Dahua County, Guangxi Province, China, based on morphological characters as well as on nrDNA (ITS) and cpDNA (trnL-F, atpB-rbcL, rbcL, matK, psbH-petB and psbA-trnH) sequences. It is characterised by unifoliate leaves similar to those of Murraya stenocarpa (Murraya sect. Bergera, or Chalcas sect. Bergera) but differs from it by having smaller and thinner subcoriaceous leaflets with irregularly toothed margins. The leaflets resemble those of M. kwangsiensis (Murraya sect. Bergera) in having hairs under the leaflets, oil glands and similar odour. Based on molecular data, B. unifolia is closely related to M. stenocarpa and M. kwangsiensis and thus it is important for resolving the classification of those species within Murraya sect. Bergera that should be formally transferred to Bergera.
