垂盆草和狭叶垂盆草的比较研究

  The Chinese medicine “Chuipencao” is studied.  But, as a matter of fact, this Chinese name represents two distinct forms, one with broad leaves and the other with narrow leaves.  As a result of a comprehensive study on gross morphology, pollen mor- phology, histological structure, isozymes, GC analysis of chemical constituents of the plants in question has shown that the narrow-leafed form is different from the broad- leafed form and therefore is considered as a new species, Sedum angustifolium Z.

中国二叠纪苏铁科新属、种——古生铁花

本文是继中国始苏铁Primocycas chinensis Zhu  et  Du之后，又报道一种古植物文献未见记载的早二叠世晚期苏铁科小孢子叶球，命名为古生铁花(新属、种)Cycadostrobilus  paleozoicus  Zhu，gen. et.sp．nov．标本采自我国山西省太原市东山煤矿的下石盒子组，它是世界迄今已知的一种最古老的小孢子叶球化石。和本新属同层发现的化石，除了中国始苏铁之外，还有楔叶Sphenophyllum、齿叶Tingia，楔羊齿Sphenopteris、楔叶羊齿Sphenopteridium、织羊齿Emplectopteris、栉羊齿Pecopteris、大芦孢穗Macrostachya、科达Cordaites、带羊齿Taeniopteris、角籽Cornucarpus和几种也未见记载而形态又非常特殊的植物。本文认为当前报道的古生铁花(新属、种)很可能和中国始苏铁同属一种植物，其营养叶可能是疏脉带羊齿Taeniopteris norinii Halle。

铁线莲属研究随记(Ⅰ)

于1999年5月至9月,作者先后访问了K、BM、P和S四个植物标本馆,在查阅他们收藏的铁线莲属植物标本的过程中,发现该属的一些分类学问题：(1)发现过去一些学者分别错误地将Clematis montana var．brevifoliola Kuntze,C．apiifolia var．biternata Makino,C．subumbellata Kurz,C．goudotiana Planch．&; Triana,C．insidiosa Baill.,C．kockiana Schneid．和C．longicauda A．Rich．等加以归并,这些均应予以恢复。(2)发现过去发表的subsect．Africanae M．Johnson,C．umbellifera Gagnep.,C．pubescens Benth.,C．rhodocarpa Rose,C．edentata Baker,C．djalonensis Cheval.,C．oliveri Kuntze,C．tibetana ssp．vernavi var．dentata Grey-Wilson,C．yunuanensis var．brevipedunculata W．T .Wang,C．clarkeana var．stenophylla Hand．-Mazz,C．subfalcata Pei ex M．Y．Fang,C．angustifoliola W．T .Wang,C．dasyandra var．polyantha Finet &; Gagnep.等学名不能成立,应加以归并。(3)对构成黄花铁线莲组sect．Meclatis的二亚组给出新的特征集要;根据C．sericea B．H．K．ex DC．与C．grossa Benth．的形态区别不大,有时甚至难以区分以及二者的分布区一南一北互相邻接的分布格局,认为二者可能为一对姊妹群,并将其等作为一个种的两个地理变种处理;认为在非洲大陆广布并分布到阿拉伯半岛的C．hirsuta Perr．&; Guill．包含4变种;将过去置于C．oweniae Harv．的变种var．jonodii移到此种中,并根据C．inciso-dentata A．Rich．特殊的绵毛毛被和内面无毛的萼片等特征,否定过去一些学者将其归并于C．hirsuta的意见,也将其作为C．hirsuta的一个变种处理。(4)描述了单性铁线莲组sect．Aspidanthera的一个特产马达加斯加岛的新亚组subsect．Insid iosae W．T．Wang和尾叶铁线莲亚组subsect．Connatae的一个特产非洲大陆的新系ser．Grandiflorae W．T．  Wang以及8新种、1新变种。(5)发现杨宗愈等(1991)报道的秀丽铁线莲C．grata Wall．在我国7省区 (西藏东部、云南、四川、贵州、湖北、湖南、江西)有分布所依据的8号标本均非C．grata,而分别是与此 种相近缘的5个种或变种。(6)发现了伏毛绣球藤C．montana var．brevifoliola Kuntze(原知分布于锡金和印度西北部)在我国西藏、尼泊尔、不丹和缅甸北部,缅甸铁线莲C．burmanica Lace(原知分布于缅甸和 泰国)在我国云南西南部,小木通C．armandii Franch．(原知分布于我国长江流域、越南)在缅甸北部和印 度东北部,以及俞氏铁线莲C．yui W．T．Wang(原知分布于我国云南西北部和西藏东南部)在缅甸北部 的新分布。

鄂报春(Primula obconica Hance)一新亚种

 A new subspecies, Primula obconica subsp. fujianensis, is described. The genus Primula is widely distributed throughout China, but it has never been previously recorded in Fujian and Jiangsu. Recently the authors collected a specimen of the genus from Fujian for the first time. It is obviously closely related to P. obconica, which is one of the most common species in China, ranging from western Yunnan and Sichuan through Guizhou, Hubei to Hunan and northern Guang- dong, with its most easterly extension in southern Jiangxi. Morphologically, the Fujian plant is char- acterized by its much smaller stature and by the scapes being shorter than the leaf rosette, and in many ways it is more closely related to P. obconica subsp. parva, but can be easily distinguished by its smaller, white and homostylous flowers. As it is isolated both in distribution and reproductionwith other subspecies of P. obconica, here it is described as a new subspecies.
