In this paper, a new species——Yinshania exiensis Y. H. Zhang is described. The characters of the new species are similar to those of Y. chayuensis (Ser. Yinshanis) and Y. furcatopilosa (Ser. Henryanae). It is distributed in western Hubei. There are two sections and two series under the genus Yinshania. After the investigating of evolutional direction of the principal characters of Yinshania, it is considered that the Sect. Yinshania is an original group, and the Sect. Microcarpae is an advanced group. Western...

本文描述了阴山荠屑一新种——鄂西阴山荠Yinshania exiensis Y.H.Zhang。新种隶阴山荠系,但形态特征介于阴山荠系的察隅阴山荠和密毛系的叉毛阴山荠之间,分布在鄂西一带。阴山荠属属下系统有2组2系,在研究了本属主要性状特征的演化方向后,本文认为阴山荠组是较原始的一群,小果组是较进化的一群。四川西部及其邻近地区是本属的近代分布区中心或分化中心,本属也可能是从该地区分化起源的。

The family Hamamelidaceae is one of the core (or key) groups for studying the phylogeny of Hamamelids. It is an important taxon for the palaeobotanists and the botanists in discussing the origin and early evolution of the angiosperms owing to its strong differentiation of gross and pollen morphological characters. In this paper, the systematic position, modern distribution pattern and fossil history of the genera are analyzed, and the place and time of origin of the family are discussed according to the principle...

The family Hamamelidaceae is one of the core (or key) groups for studying the phylogeny of Hamamelids. It is an important taxon for the palaeobotanists and the botanists in discussing the origin and early evolution of the angiosperms owing to its strong differentiation of gross and pollen morphological characters. In this paper, the systematic position, modern distribution pattern and fossil history of the genera are analyzed, and the place and time of origin of the family are discussed according to the principle of the unity between the phylogeny and distribution of plants. The paper consists four parts.

本文利用系统发育与地理分布相结合的方法,探讨金缕梅科各属植物的系统位置和分布式样,并结合化石、古地理及古气候等证据,讨论该科的分布中心、可能的起源时间和地点以及现代分布式样形成的原因。研究结果表明:全世界金缕梅科植物共30属144种,间断分布于亚洲西部、东部、东南部,非洲东部、南部,大洋洲的澳大利亚东北部以及中美洲和北美洲的东南部,欧洲和南美洲尚无现代类群分布的记载。它基本上是一个热带和亚热带山地分布的科。通过对该科30个属的系统位置及其分布式样的分析,将金缕梅科属的分布归纳为:A.热带分布类型(18属),包括(1)热带亚洲分布(11属),(2)热带中美洲分布(2属),(3)热带非洲分布(2属),(4)热带大洋洲分布(3属);B.温带分布类型(12属),包括(5)东亚分布(7属),(6)西亚分布(2属),(7)西亚-东亚-北美间断分布(1属),(8)东亚-北美间断分布(1属),(9)北美分布(1属)。东亚区南部到印度支那区北部(即中国长江以南至中南半岛北部地区)是它的现代分布区中心;根据化石证据、原始类型分布和外类群分布分析,提出该科植物起源于劳亚古陆,并曾经有一个很长的白垩纪历史,至少在早白垩纪...
