近代由于清政府错误的治藏政策使民国政府成立之后,西藏地方政府与民国中央政府的关系一直处于松弛甚至中断的状态。刘曼卿是拉萨人,后在南京国民政府任职,刘曼卿关心边疆局势,1929年申请赴藏沟通民国中央政府与西藏地方政府的关系,并取得显著成果。民国政府为恢复与西藏地方政府的一系列努力为刘曼卿入藏做好了铺垫。 相似文献

When the genus Yinshania Ma et Y. Z. Zhao was published, it had
only a single species, Y. albiflora Ma et Y. Z. Zhao which was indicated as the
type of the genus (Acta Phytotax. Sin. 1979). Y. Z. Zhao 155. was indicated as
the type specimen of Y. albiflora. It is adequate to cite Y. albiflora Ma et Y. Z.
Zhao as the type of genus Yinshania Ma et Y. Z. Zhao. In a revision (Acta Phyto-
tax. Sin. 25(3): 204-219, 1987) Y. H. Zhang made a combintion, Yinshania
acutangula (O. E. Schulz) Y. H. Zhang (=Cochlearia acutangula O. E. Schulz)
and reduced Yinshania albiflora Ma et Y. Z. Zhao as a variety of Y. acutangula,i.
e. Y. acutangula var. albiflora (Ma et Y. Z. Zhao) Y. H. Zhang. She is uncorrect,
however, when she cited Y. acutangula (O. E. Schulz) Y. H . Zhang as the type
of the genus Yinshania Ma et Y. Z. Zhao. It should be cited as follows:
Yinshania Ma et Y. Z. Zhao
Typus generis: Yinshania albiflora Ma et Y. Z. Zhao (=Yinshania acutangula(O. E. Schulz) Y. H. Zhang var. albiflora (Ma et Y. Z. Zhao) Y. H. Zhang) 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

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
