中国姜花属基于SRAP分子标记的聚类分析

依据苞片是覆瓦状排列或是卷筒状排列而把姜花属Hedychium分为两个亚属的分类法近年颇受质疑.本文利用30对多态性好的随机引物,对中国姜花属的19种1变种共22份材料进行SRAP分子标记分析.其中最有效的28对引物共扩出152条带,当中135条为多态性带,占88.8%.平均每对4.8条,多态性条带里最多的为引物组合F13R1,达到13条.聚类分析表明:(1)中国姜花属植物可分为三个类群:第1群植株较矮小,主要分布于石灰岩地区;第Ⅱ群与第Ⅰ群每苞片均具2朵以上的小花,但植株较高大且基本上不分布于石灰岩地区;第Ⅲ群每苞片仅具1朵小花.此结果与Wood(2000)用ITS分析得出的结果基本一致.(2)支持吴德邻和Larsen(2000)把H. emeiense Z.Y Zhu归并为峨眉姜花H.flavescens Carey ex Roscoe的观点.(3)盘珠姜花H.panzhuum Z.Y Zhu与黄姜花H.flavum Roxb.是同一种植物,即盘珠姜花是黄姜花的晚出同名.(4)土壤基质可能是导致姜花属物种分化的重要因素.作者认为根据每苞片有花多少的特征,在系统学上可把姜花属分为两个类群:A类群,每苞片仅有1朵小花:B类群,每苞片有2朵以上的小花.

紊蒿属一新种和对该属分类及演化的讨论

对新种多头紊蒿(Elachanthemum polycephalum Z.Y.Zhu et C.Z.Liang)的形态特征进行了描述,并从形态和生态特征、地理分布及其区系起源等方面探讨了紊蒿属(Elachanthemum Y.Ling et Y.R.Ling)的分类地位。结果表明：紊蒿属与百花蒿属(Stilpnolepis Krasch.)在形态上虽有相近之处,但花、果实和花粉等形态差异明显,因而不能并入百花蒿属,而应独立成属。该属起源于第三纪亚洲北部的古蒿类群(Pro-Artemisia L.),是蒿类中较为原始的属,为古地中海东部残遗的旱生成分,也是现代亚洲中部荒漠(戈壁荒漠)的持有属;多头紊蒿新种的发现,使紊蒿属从单种属变成寡种(双种)属,表明荒漠植物区系的物种分化仍在进行。     

脓疮草复合体的形态性状分析与分类修订

脓疮草复合体(Panzerina lanata complex)隶属于唇形科脓疮草属,原有6个合法学名。通过从内 蒙古、陕西、甘肃、宁夏及新疆等5个省或自治区的22个居群取样,进行野外和移栽后的对比观测及性 状分析,并结合多变量统计分析,从不同水平和角度对复合体进行了研究。结果表明,此复合体的根、茎 等都是环境可塑性很高的性状,叶次之,而花部、果实和种子性状的可塑性较小。以往划分复合体类群 的叶裂程度、茎叶被毛及萼齿形态等几个鉴别性状在天然居群中连续变化,以此划分的几个“种”,不过 是连续变异的极端个体。再结合地理分布的特征,将P．alaschanica、P．kansuensis和P. albescens归并 在P．1anata中,同样可证明P．argyracea不存在。对22个居群11个形态性状的统计学和主成分分析 与性状分析结果一致。研究表明,该复合体小坚果表面具疣与否、花冠超出萼筒的多少及花干后变色与 否等是其分种性状,以此分种标准该复合体可分为2种:Panzerina lanata(L．)Sojak和Panzerina parviflora(C．Y．Wu et H．W．Li)Y．Z.Zhao．

国产三角瓣花属(茜草科)订正

三角瓣花属Prismatomeris Thw．在Hooker(1873)和K．Schumann(1891)的茜草 科分类系统中隶于巴戟族Morindeae Miq．但在 Bremekamp(1966年)的分类系统中,其分类 位置未定。本属的胚根下位,花冠裂片镊合状排列和具针晶等特征与巴戟族相同,但它的花 离生,子房2室,胚珠盾形而着生于子房隔膜上半部等特征则与巴戟族明显不同。 因此, 将本属分立作族并置于Bremekamp所定界的茜草亚科Rubioideae中似乎较合适。 本文还提 供了经挑选的本属10对特征及其分类价值的说明。辨别了两个种：(1)将分布于中国的P. tetrandra(Roxb．)K．Schum. 修订为 “P.tetrandra (Roxb.) K. Schum. subsp. multiflora (Ridley,)Y．Z．Ruan”. (2)P. connata Y． Z. Ruan 被记述作新种它的热带新亚种是 P. connata Y． Z． Ruan subsp. hainanensis Y． Z． Ruan。     

中国竹亚科空竹属的整理

我国竹亚科空竹属(Cephalostachyum Munro)植物发现于云南和西藏两省区,集中分布于云南。根据形态学性状,以及近年来叶片微形态和分子系统学研究结果,作者对我国空竹属物种进行了整理并编制了分种检索表。结果显示,我国空竹属现知有7种,云南均有分布:薄竹(Cephalostachyum chinense(Rendle)D.Z.Li et H.Q.Yang)、空竹(C.fuchsianum Gamble et Hook.f.)、独龙江空竹(C.mannii(Gamble)Stapleton et D.Z.Li)、小空竹(C.pallidum Munro)、屏边空竹(C.pingbianense(Hsueh et Y.M.Yang ex Yi et al.)D.Z.Li et H.Q.Yang)、红毛空竹(C.sanguineum(W.P.Zhang)D.Z.LiH.Q.Yang)、真麻竹(C.scandens Bor)。薄竹属(Leptocanna Chia et H.L.Fung)和毒空竹(C.virulentum Y.M.Yang et F.Du)分别为空竹属和空竹的异名。另一方面,原置于空竹属的香糯竹(C.pergracile Munro)和金毛空竹(C.virgatum(Munro)Kurz)的形态特征则更接近狭义的竹属(Schizostachyum Nees),应该处理为狭义竹属成员。本研究对空竹属今后的修订工作有重要意义。

Morpho-anatomical differentiation of the balkan populations of the species Teucrium flavum L. (Lamiaceae)

Ecological plasticity, i.e., inter-population differentiation of the species Teucrium flavum was analyzed on the basis of morpho-anatomical variability of its five populations from the maquis (Cisto-Ericetea and Cisto-Micromerietea), rocky grounds (Festuco-Brometea) and rocky crevices (Asplenietea rupestris) in the Eumediterranean and sub-Mediterranean region. Univariate statistic analysis included 22 quantitative characters related to the leaf and stem anatomy and morphology. In order to establish the variability and significance of morpho-anatomical differentiation, principal component analyses (PCA), multivariate analyses of variances (MANOVA), discriminant components analysis (DCA) and clustering, according to the UPMGA method based on Mahalanobius’ distances, have been done.The morpho-anatomical analysis of plants from the five distant populations confirmed that the species T. flavum belongs to malacophyllous xeromorphic species. It was established that the plants from all the five populations analyzed are distinguished by stable conservative xeromorphic characteristics. There is a difference between the pronounced xeromorphic plants belonging to Eumediterranean populations and the subxeromorphic sub-Mediterranean ones.

William Roxburgh’s eye plant and its relevance in the nomenclature of <Emphasis Type="Italic">Phaeanthus</Emphasis> (Annonaceae)

An attempt is made to discover the identity and correct name for Uvaria tripetala Roxb., Uvaria tripetala Blanco, Phaeanthus nutans Hook. f. & Thomson and Uvaria ophthalmica Roxb. ex G. Don (Annonaceae). It is concluded that all but one belong to what has been called Phaeanthus ebracteolatus (C. Presl) Merr., which must now be referred to correctly as Phaeanthus ophthalmicus (Roxb. ex G. Don) J. Sinclair. The correct name for the species that has generally been called Phaeanthus nutans or Phaeanthus ophthalmicus is Phaeanthus intermedius (P. Parm.) I. M. Turner & Veldkamp. Typification of these names and their known synonyms is presented. This includes four new lectotypifications and the designation of two new epitypes and one new neotype.
