In this paper the classification of the genus  Bergenia Moench is  provided, its geographic distribution analysed, and the phylogeny also traced.   Based  on an analysis of morphological characters such as leaves, ocreas, branches of inflorescences, Pedicels, hypan- thium, sepals, and glandular indumentum, thi genus is divided into 3 sections: 1. Sect. Scopu- losae J. T. Pan, sect. nov., 2. Sect. Bergnia, 3. Sect. Ciliatae (A. Boriss.) J. T. Pan, stat. nov. The Sect. Scopulosae J. T. Pan may be considered as the primitive one, while Sect. Ciliatae (A. Boriss.) J. T. Pan may be regarded as the advanced one, with Sect. Bergenia in between.         So far, the genus Bergenia Moench comprises 9 species in the total.  Southeast Asia and North Asia (south and east Siberia, USSR) each have only 1 species, West Asia (Afghanis- tan) has 2, Central Asia (Kirghizia-Tajikistan-Uzbekstan area, USSR) 3, South Asia 4 (Nepal has 4, India, Pakistan and Kashmir area each has 3, Bhutan and Sikkim each has 2), East Asia 6.  In East Asia, Mongolia and Korea each have only 1 species, but China has 6 (includ- ing endemic species 2 and new species 1).  Sichuan Province and Xizang Autonomous Region each have 3, Yunnan Province 2, Shaanxi Province (Qinling Mountains) and Uygur Autono- mous Region of Xinjiang each have only 1.        Thus the distribution centre of this genus  should be in the region covering Si- chuan, Yunnan and Xizang. Moreover, it is noteworthy  that Bergenia scopulosa T. P. Wang in Sect. Scopulosae seems to have retained primitive characters,  for exa- mple, non-ciliate leaves and ocreas, glabrous pedicels, hypanthium and  sepals,  and this primitive species is found in Qinling Mountains and Sichuan.  According to the distribution of the primitive species, the author suggests that the centre of origin of  this genus be in the region covering Qinling Mountains and Sichuan.  相似文献

自我们近年发表一系列牡丹组分类文章以来, 国内外基本上赞同我们8个种的分类系统,但对一些问题仍有不同见解。本文进一步申述牡丹Paeonia suffruticosa Andrews 是一个独立的种而不是人工杂种, 以及银屏牡丹P. suffruticosa ssp. yinpingmudan是牡丹P. suffruticosa的野生类型而不是逸生的P. ostii的理由。上述论点也得到了分子树的支持。P. jishanensis T. Hong & W. Z. Zhao是一个合法名称, 而P. spontanea (Rehder) T. Hong & W. Z. Zhao则确实是一个多余名。太白山紫斑牡丹的学名应是P. rockii ssp. atava (Brühl) D. Y. Hong & K. Y. Pan, 因此P. moutan Sims ssp. atava Brühl不应是可疑的分类群。本文还对Halda的6个组合和两个杂交种名作了处理。结果, 本文包括了5个新异名和一个新组合。  相似文献

  Peristylus is a genus of over 60 species, mainly distributed in the Old World tropics, with many species extending northwards to central China.   In the present paper, the taxa of the genus hitherto recorded in China are taxonomically and phytogeographically dis- cussed and revised, and, as a result, 20 species are recognized, including one new species, P. jinchuanicus K. Y. Lang, and four new combinations, P. bulleyi (Rolfe) K. Y. Lang, P. for- restii (Schltr.) K. Y. Lang, P. longiracemus (Fukuyama)  K.  Y.  Lang and  P. neotineoides (Ames et Schltr.) K. Y. Lang. A full list of synonyms is given, a key to the species is pro- vided and the distribution areas in China of all the taxa are mapped.  相似文献

 作者在调查研究云南省柴胡植物过程中,发现两个新种,定名为韭叶柴胡 Bupleurumkunmingense Y.Li et S.L.Pan 和多枝柴胡B.polyclonum Y.Li et S.L.Pan,  并进行了挥发油和皂甙成分的初步分析,发现两新种的挥发油紫外吸收光谱及薄层层析图与北柴胡B.chinense DC.的很相似; 且所含柴胡皂甙均高于北柴胡,故二者可以作为药用柴胡中的优质品而予以重视。  相似文献

 Paeonia suffruticosa Andrews subsp. spontanea (Rehder) S. G. Haw et L. A.  Lauener (  =P. spontanea = P. jishanensis) has been considered as the wild form of widely  cultivated P.  suffruticosa.  However,  the subspecies differs from the cultivated one in  shape, division and indumentum of leaves and reproductive biology. As a result of extensive  field work, a form with two individuals in Yinping Shan, Caohu, Anhui, and Songxian,  Henan, are found to be extremely similar to P. suffruticosa, but apparently different from  P. jishanensis. The form is considered to be the wild one of P. suffruticosa and described as new: P. suffruticosa subsp, yinpingmudan Hong, K. Y. Pan et Z. W. Xie.  相似文献
