铁线莲属研究随记(Ⅴ) 总被引:3,自引:0,他引:3
(1)描述了9新种,4新变种;做出了2新等级,1新组合和1新名称。(2)归并了以下拉丁学名:Clematis dioica L.ssp.virginiana(L.)Kuntze var.bahamica Kuntze,C.bahamica (Kuntze) Britton,C.orbic-ulata Correll,C.brasiliana DC.var.laxa St.Hilaire,C.perulata Kuntze,C.barranacae Jones,C.discolorGardn., C.laxiflora Baker,C.bathiei Lévl.和C.mauritiana Lam.var.sulfurea Viguier &; Perrier。(3)对威灵仙C.chinensis Osbeck的5个变种进行了分类;特产日本的C.fujisanensis Hisauti &; Hara与C.chinensis极为相近,主要区别在于具较大的花,但有时花与C.chinensis的花同样大,由于区别不大,在本文中被降级作变种处理;与其近缘、具强烈退化花序、特产华东的C.anhweiensis M.C.Chang也随之被处理为变种。(4)瑞典学者Johnson在最近出版的铁线莲属专著中将特产西印度群岛东部的C.Flukenetii DC.归并于特产美国东南部的C.catesbyana Pursh;本文不同意他做出的归并,并列出了这两个种的明显区别特征,确认后者是一个应该得到承认的独立的种。(5)根据墨西哥标本描述的C.acapulcensis Hook.&; Arn.原知分布于中美一带,而其在南美的居群和一小叶多毛的新变种(var.puberula)过去长期间被误定为其近缘种C.affinis St.Hilaire;这个混乱在本文中得到澄清,同时,本文给出了这二近缘种的区别特征。(6)Viguier和Perrier两位学者在上世纪四十年代末研究马达加斯加一带的黄花铁线莲组-怀特铁线莲亚组(sect.Meclatis subsect.Wightianae)植物时做出了不少错误鉴定:(a)将特产马达加斯加的具三出复叶的C.mauritiana Lam. var.mauritiana,var.coriacea和C.microcuspis Baker,以及具单叶的C.ac-tinostemmatifolia W.T.Wang均鉴定为分布于非洲大陆的C.simensis Fresen., 并将后者作为分布于亚洲和欧洲的C.orientalis L.的亚种处理;(b)将特产马达加斯加具三出复叶的C.laxiflora Baker和具一回羽状复叶的C.ibarensis Baker鉴定为特产印度南部的C.wightiana Wall.,也将后者作为C.orientalis的亚种处理;(c)将特产科摩罗(Comoros)具二回羽状复叶的C.comoresensis W.T. Wang鉴定为C.brachiata Thunb.,也将后者作为C.orientalis L.的亚种处理;(d)将C.ibarensis Baker(具一回羽状复叶和两性花)这一拉丁学名用在了另一特产马达加斯加具2~3回羽状复叶和单性花、应属于单性铁线莲组sect. Aspidanthera的种(C.rutoides W.T.Wang)之上;(e)将另一特产马达加斯加具一回羽状复叶和单性花、 也属于单性铁线莲组的C.edentata Baker(=C.insidiosa Baill.)降级作为这两位学者曲解的C.ibarensis Baker的亚种处理;(f)将特产马达加斯加的C.dissecta Baker归并到属于茴芹叶铁线莲组(sect. Pseudanemone)的C.pimpindllifolia Hook.中。此次本文第五部分继去年第一、二部分之后对上述混乱情况做出了完全澄清,并给出了分布于马达加斯加及其邻近岛屿的怀特铁线莲亚组8种植物的检索表;由于C.ibarensis Baker的定义被上述两位学者严重误解,本文根据较多具花、果的标本写出了此种完整、正确的形态描述。 相似文献

( 1 ) Nine species and 4 varieties are described as new, and 2 new ranks, 1 new combination, and 1 new name are proposed. (2) Clematis dioica L. ssp. virginiana (L.) Kuntze var. bahamica Kuntze, C. bahamica (Kuntze) Britton, C. orbiculata Correll, C. brasiliana DC. var. laxa St. Hilaire, C. perulata Kuntze, C. barrancae Jones, C. discolor Gardn., C. laxiflora Baker, C. bathiei Lévl., and C. mauritiana Lam. var. sulfurea Viguier & Perrier are reduced into synonymy. (3) A new classification for the varieties of C. chinensis Osbeck is proposed. (4) The specific status of C. flukenetii DC. is discussed and confirmed. (5) The differences between C. acapulcensis Hook. & Arn., the South American population of which has been misidentified as C. affinis St. Hilaire, and its close ally, C. affinis St. Hilaire, are given. (6) The taxonomical confusion made by Viguier and Perrier about the species belonging to sect. Meclatissubsect. Wightianae distributed in Madagascar and adjoining islands is clarified, and an enumera-tion of them with a key is given. 相似文献

大花黄牡丹分类学地位的研究 总被引:9,自引:0,他引:9
通过野外调查、引种试验,对大花黄牡丹与黄牡丹的形态特征、生长和繁殖特性进行了综合比较研究,结果表明,二者之间在植株高度、心皮数目、花色、花瓣基部有无棕红斑及繁殖特性等存在明显差异;同时,染色体组型、带型及蛋白亚基构成分析也表明二者之间有明显差异,因此我们认为,大花黄牡丹应上升为种的等级:Paeonia ludlowii(Stern et Taylor)J.J.Li et D.Z.Chen,stat 相似文献

This paper deals with karyotype analysis of three taxa of Fritillaria, i. e. F.thunbergii (from Yinxian and Zhoushan), F. thunbergii var. chekiangensis, and F. anhuiensis.The results show that all the three taxa are diploid (2n = 24) and their karyotypes are different. The karyotype formulae may be summarized as follows: F. thunbergii: Yinxian, 4m(lsc)+4st(lsc) l) +16t(lsc) ; Zhoushan, 2m+2sm+12st(lsc) +8t(2sc) . F. thunbergii var.chekiangensis2m+2sm+8st (2sc) +12t (4sc). F. anhuiensis 2m+2sm+8st (2sc) + 12t (5sc). Thereare many secondary constrictions in all the three taxa of Fritillaria studied, but the numberand positions of secondary constrictions are quite different in different taxa. 相似文献

贝母属(Fritillaria L.)植物是一类重要的药用和观赏植物,具有较高的经济价值。据资料记载,安徽省共有贝母属植物11种,2变种和1变型。由于对贝母属植物的种系划分上存在很大的分歧,因此,在大量的实地调查和资料研究的基础上。对安徽贝母属植物的分类等研究现状进行了综述,并对未来的研究利用进行了展望,旨在为安徽贝母属植物的进一步研究和开发利用提供参考依据。 相似文献
