中国阿魏属的细胞分类学研究

本文首次报道和分析了阿魏属Ferula L.分布区东缘3个种的染色体数目和核型。 太行阿魏F.licentiana Hand.-Mazz．的核型公式为2n=22=14m+2sm+6st(2sat),铜山阿魏F．licentiancHand．-Mazz．var．tunshanica(Su)Shan et Q．X．Liu的核型公式为2n=22=14m+8st(2sat),硬阿魏F．bungeana Kitag．的核型公式为2n=22=12m+6sm+2st。  它们的核型都属2A型．在此基础上从染色体角度进一步论证了铜山阿魏作为太行阿魏的变种和硬阿魏从近前胡亚属  Subgen.Peucedanoides(Boiss.)Korov．中分出的合理性．根据已有资料,提出该属的染色体基数为X=11,基本核型公式为2n=22=14m+4sm+4st。  本属核型对称性偏高,核型变异性偏小,与该属的自然性和稳定性以及该属的分类地位的合理性和可靠性相吻合。  本文还分析了国产阿魏属内各种类的核型,进化程度,并对它们进行了细胞分类处理,对于出现与经典分类不一致的原因进行了讨论。

根据对12个国家53个标本馆收藏的5,000余份五味子属Schisandra植物标本的研究,结合野外调查和采集,对世界范围的五味子属种类作了分类学订正。在五味子属中,10个种被确认,22个种、7个亚种、14个变种和1个变型的名称被作为新异名。文中附有分种检索表。     

杜鹃属植物的化学分类学研究

 本文通过对177种(或亚种,变种)杜鹃叶中16种黄酮类化合物和3种其它酚性成分的高效硅胶薄层阶式层析和聚酰胺薄层层析,发现中国杜鹃属植物中的黄酮类成分的共同特征是存在着槲皮素的多种单糖甙;有的属下类群以几种甙共存或某种甙缺乏为特征;杨梅树皮甙。棉子皮亭甙尽管不是普遍检出的成分,但在某些属下类群中分布较集中,具有独特的分类价值．作者进一步讨论了化学性状的定量或半定量研究对杜鹃属植物化学分类的意义。     

栝楼属花粉形态研究及其在分类学上的意义

 本文收集了国内外栝楼属Trichosanthes 31种1变种,在光学显微镜和扫描电镜下,进行了花粉粒形态的比较观察。该属花粉粒为3孔沟型,外壁表面纹饰可分为四个类型,即：疣状或皱波状(小苞组),粗网状(大苞组),细网状或光滑(叶苞组),近光滑或皱波状(王瓜组)。这四个类型的划分与植物形态分类基本一致,可作为分组及分种的依据之一。花粉特征支持将叶苞组分为叶苞亚组和柔毛亚组,如叶苞亚组有明显的沟,而柔毛亚组没有。     

等片藻属几个种的分类学问题研究

本文使用光学显微镜和扫描电子显微镜对等片藻属Diatoma的6个种：冬季等片藻 D·hiemale(Roth)Heib．、巨大等片藻D．maximum(Grun．)Fricke、中型等片藻D．mesodon(Ehr)Kuetz．、念珠状等片藻D．moniliforme Kuetz．、纤细等片藻D. tenue Ag.、等片藻D,vulgare Bory及其下的4个变种作了研究,并讨论了它们的分类学问题。     

泰国茜草科粗叶木属植物的分类学研究

在详细检查了K,BM,E,P,AAU,L,KEP,BKF,BK,SING,PSU等标本馆馆藏茜草科粗叶本属Lasianthus Jack.植物标本基础上,研究了泰国产粗叶木属植物的分类学,共归并7个种名,建立3个新种,3 个新变种,1个新等级,以及8个泰国分布新记录种及8个泰国分布新记录变种,确认泰国共有粗叶木属植物52种,1亚种,12变种;讨论了易于混淆的种的界线、它们可能的亲缘关系以及识别要点。     

凤仙花属种子形态及其在分类学上的意义

本文首次记载了对分布于峨眉山的凤仙花属Impatiens 12种植物的种子表面显微结构的观察,并分析了种子表面形态在该属种水平上的分类价值及可能的系统学意义。种皮表层细胞特化、排列方式、隆起状态、种脊上近合点端的突起、种子末端附属物的有无及其形态等性状被视为凤仙花属种子表面的主要特征。依据这些性状12种凤仙花种子形态分为两种类型：1．种子表面光滑,无明显大、小细胞分化。如白花凤仙I．wilsoni可能具3沟花粉凤仙花的种子形态的特点。2．表面粗糙,有明显大、小细胞的分化及不同程度的细胞隆起,并呈现出多种特异形态．这代表了以一年生草本,4沟花粉为特点的凤仙花种子形态特征。种子特征与植物体习性、花形态及花粉形态相关,在一定程度上反映了属内类群的分化,因而在凤仙花科、属的分类和系统研究中是不可忽视的性状。

中国-喜玛拉雅特有属——蓝钟花属的分类修订

 Cyananthus Wallich ex Bentham, the only genus of Campanulaceae with superior ovary, is revised to clarify infrageneric relationships and phylogeny of the genus. Evidence obtained from the comparative gross morphology, anatomy, palynology, and karyomorphology recommends a new infrageneric classification of the genus, recognizing 23 species, belonging to two subgenera, four sections and four subsections. One subgenus(Subgen. Micranthus), one section(Sect. Suffruticulosi) and two subsections(Subsect. Flavi and Subsect. Lichiangenses)are described as new taxa. New combinations at sectional(Sect. Annui) and subsectional(Subsect. Stenolobi) ranks are also proposed. The genus Cyananthus is strictly distributed in the high mountains of China(Xizang, Yunnan and Sichuan), extending to Bhutan, Nepal and India(Kumaon-Garhwal, Assam and Sikkim), with altitudinal ranges from 2500～5300 m. It is observed that 13 species are endemic to SW China and only three species are endemic to the Himalayas(two species in Nepal and one to NW India). It is evident that Cyananthus is one of the most primitive genera of Campanulaceae and within the genus, subgenus Cyananthus(Sect. Stenolobi) is more primitive than the subgenus Micranthus. It is also suggested that SW China(most probably Yunnan) is the center of origin of Cyananthus, considering the occurrence of as many as 20 species of Cyananthus, representing several primitive taxa and many endemic species.

柏科的分类和分布:亚科、族和属

 柏科Cupressaceae和杉科Taxcdiaceae有许多相似之处,近年来不少分类学家主张把两科合并成广义的柏科。原杉科中的金松属Sciadopitys与两科其他屑的差异较大,被提升为单种科Sciadopity-aceae。本文根据球果可育种鳞的位置把柏科(狭义)分为2亚科,即上部种鳞不可育的柏木亚科Cupres-soideae和上部种鳞可育的澳洲柏亚科Callitroideae。综合其他形态学和解剖学证据,柏木亚科又分4族,即柏木族Cupresseae(包括：柏木属Cupressus、杂交柏属X Cupressocyparis、扁柏屑Chamaecyparis和福建柏属Fokeinia)、侧柏族Thujopsideae(包括：崖柏属Thuja、罗汉柏属Thujopsis和侧柏属laty-ladus)、圆柏族Junlpereae(包括：圆柏属Junzperus和海参威柏属Microbiota)以及香漆柏族Tetraclineae(包括：翠柏属Calt*edrus和香漆柏属Tetraclinis)。澳洲柏亚科又分3族,即澳洲柏族Actinostrobeae(包括：西澳柏属Actinostrobus、澳洲柏属Callitris、智利柏属Fitzroya和杉叶柏属Neocallitropsis)、南非柏族Widdringtoneae(包括：白智利柏属Pilgerodendron、塔斯曼柏属Diselma和南非柏属Widdringtonia)以及甜柏族Libocedreae(包括：甜柏属Libocedrus、巴布亚柏屑Papuacedrus和南美柏属Austrocedrus)。柏科21个属的地理分布可划分为5种类型,即：(1)杂交柏属系英国选出的属间杂交类型;(2)分布非洲、欧洲、亚洲和北美洲的属,有柏木属和圆柏属2个属;(3)东亚—北美洲际间断分布的属,有扁柏属、崖柏属和翠柏属3个属;(4)分布区较窄的属,包括西澳柏属,、澳洲柏属、甜柏屑、巴布亚柏属、南非柏属5个属;(5)单种屑,包括福建柏属、海参威柏属、罗汉柏属、侧柏属、香漆柏属、杉叶柏属、塔斯曼柏属、智利柏屑、南美柏属和白智利柏属等10个属。该科属的3个地理分布中心是：东亚(9属)、北美西南部(5属)、澳大利亚及其东部附近群岛(6属)。此外,地中海沿岸分布3属,智利南部和阿根廷分布3属。     

云南叉蕨属(Tectaria Cav.)的增补与订正

叉蕨属是蕨类植物的大属之一,全世界约150种,分布于世界热带及亚热带地区。据记载,中国有27种、2变种,分布在长江以南,仅有2种北达长江以北四川境内,而大部分种类集中分布在云南。近来,笔者主要对保存在中国科学院昆明植物研究所标本室的标本进行了清理,也参考了中国科学院植物研究所标本馆的标本,这些标本不少是近年来所采集,其中,发现1新种并有1种和1变种为中国新记录,1种为云南新记录,1种为贵州新记录,有4个种名是新异名,即Tectaria cosimilis Ching et C．H．Wang,T．decurrenti-calata Ching et C．H．Wang,T．fengii Ching et C. H．Wang,T．Simaoensis Ching et C.H．Wang。至此,所知云南产叉蕨属有22种、2变种。     

中国列当属的分类及与近缘属的关系

The morphological characters in the genus Orobanche were evaluated from thetaxonomic point of view.  The author finds that the plants of this genus are relatively similarto each other in respect to characters of vegetative organs, fruits and seeds.  But the differencesin the floral structures can be served as a basis for delimitating infrageneric taxa.   The seedcoat of 18 species and pollen grains of  6 species were also examined under scanning electronmicroscope (SEM). They seem to have little significance for distinguishing species.      The result supports G. Beck’s (1930) division of the genus Orobanche into 4 sections, ofwhich 2 occur in China, based on the characters of the inflorescence, bracteoles and calyx.The author considers that some characters, such as anther hairy or not, upper lip of corollaentire or not, lower lip longer or shorter than the upper one, the state of corolla-tube inflec- tion and the hair type of filaments and plants, are important in distinguishing Chinese species. A key to the species of Orobanche in China is given.      This genus consists of about 100 species, and is mostly confined to Eurasia, with over 60 species found in Caucasus and Middle Asia of USSR, where may be the mordern  distribu- tional  centre.       Orobanche L. in China is represented by 23 species, 3 varieties and l forma. As shown in Table 1, most species (12 species) are found in Xinjiang, which clearly shows a close floristic relationship between this region and Middle Asia of USSR.  6 species are endemic to China, of which 4 are confined to the Hengduan Mountains  (Yangtze-Mekong-Salwin divide).       The relationships between this genus and related ones of Orobanchaceae are also discussed. The author holds the following opinions: the genus Phelypaea Desf. should be considered as a  member of Orobanche L. Sect. Gymnocaulis G. Beck,  the monotypic genus,   Necranthus A.  Gilli endemic to Turkey, is allied with Orobanche L. Sect.  Orobanche, the monotypic genus,  Platypholis Maxim, endemic to Bonin Is. of Japan, is far from Orobanche L. in relation and  should be regarded as a separate genus.       The 11 OTU’s, including all the sections of Orobanche L. and 7 genera of Orobanchaceae,  and 15 morphological characters were used in the  numerical  taxonomic treatment  to  test  the  above-mentioned  suggestions.   After standardization of characters, the correlation matrices were  computerized.  The correlation matrices were made to test the various clustering methods.   At   last the UPGMA clustering method was chosen and its result is shown in a phenogram.  The  result of numerical analysis is basically in accordance with the suggestions.
