新宁楼梯草的分类学订正

根据对新宁楼梯草Elatostema xinningense W.T.Wang模式标本的研究，结合在新宁楼梯草模式产地湖南省新宁县紫云山的野外调查，将新宁楼梯草降级并组合为对叶楼梯草E.sinense H.Schr⒐ter的变种。     

中国珠蕨属的分类修订

对国产珠蕨属Cryptogramma R.Br.的分类进行了修订，承认2种1变种，即稀叶珠蕨C.stelleri（Gm l.）Prantl，高山珠蕨C.brunoniana Wall.ex Hook.&Grev.和珠蕨C.bru noniana var.sinensis（Christ）G.M.Zhang。将峨眉珠蕨C.emeiensis Ching&K.H.Shing并入高山珠蕨。同时对该属的系统位置进行了讨论。     

泰国雨久花属（雨久花科）一新变种——窄叶鸭舌草

描述了泰国雨久花属Monochoria C.Presl一新变种:窄叶鸭舌草M.vaginalis var.angustifolia G.X.Wang。该新变种与原变种鸭舌草M.vaginalis var.vaginalis都具有类似的总状花序，但前者的叶片为窄披针形，3-7×0.3-2.0cm，叶片宽长比在0.1-0.4之间，叶基部裂片最长不超过2mm，总状花序具花3-7朵，而原变种鸭舌草的叶片较宽，为卵心形或心形，4-9×2-8cm，叶片宽长比在0.5-0.95之间，叶基部裂片最长可达到2cm，总状花序     

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。     

毛榛复合体（桦木科）多变量形态学研究及分类学处理

Corylus mandshurica Maxim. & Rupr. 和 C. sieboldiana Blume 在中国和俄罗斯一直被处理为独立的种。本文对来自不同标本室的这两个种的腊叶标本及野外采集的大量叶片进行了形态学分析，以确定形态分化是否足够成为建立种的依据。对采自中国、韩国和日本覆盖两个种分布区的153份标本的18个形态学性状进行了统计，以构建数据矩阵用于主成分分析。结果表明，包含C. sieboldiana 复合体的数据单位（entities）在所有的形态学性状上均呈现出广泛的重叠区域。叶片和果实性状分析结果表明类群间缺乏分异性。基于形态学性状不足以把 C. mandshurica 从C. sieboldiana 中分离出去，并给予种的等级,也就是说这两个类群在形态上没有完全分化，而且它们的分布区也是相连的。 因此，应该把C. mandshurica作为C. sieboldiana 的种下分类群处理。C. sieboldiana在韩国南部和日本的具短总苞的植物常常被处理为独立的种或变种，但实际上应该作为C. sieboldiana 内的变型处理，因为总苞性状高度变异，即使在同一个体上也是如此。     

铁线莲属研究随记（Ⅳ）

(1)Eichler(1958)在研究马来西亚铁线莲属植物时也深入地研究了中国、越南、泰国、缅甸及喜马拉雅山区的该属标本，认为根据我国台湾标本描述的Clematis taiwaniana Hayata可能为C．javana DC．的异名。本文作者在研究了有关的南洋群岛、中国台湾及日本琉球群岛的标本之后同意Eichler的归并意见；此外，C．grata Wall．var．ryukiuensis Tamura，C．sikkimensis(Hook．F.&; Thoms．) Drumm．ex Burkill，C．connata DC．var．bipinnata M．Y．Fang，C.kilungensis W．T. Wang &; M．Y. Fang等拉丁学名也被归并为异名。(2)对大叶铁线莲组sect．Tubulosae做出了新的分类系统。特产日本的Clematis takedana Makino 自发表后一直被认为是C．apiifolia DC．和 C.stans Sieb．&; Zucc．(大叶铁线莲C．heracleifolia DC．的近缘种之一)的杂交种。此种为木质藤本植物，具三出复叶，腋生花序有多数两性花，呈圆锥状，而相似于C.apiifolia DC．(萼片水平开展，雄蕊无毛，花药狭长圆形，药隔顶端不突出)，但其萼片向斜上方开展(花萼宽钟状)，花丝上部有疏柔毛，花药条形，药隔顶端有短突起而不同。笔者发现，特产我国河北西部和北京山地的羽叶铁线莲C．pinnata Maxim．(叶为具5小叶的羽状复叶)具有与C．takedana Makino相同的花构造，二者在亲缘关系上极为相近，组成一个自然小群。这二种与特产北京的细花铁线莲C．tatarinowii Maxim．(花两性，萼片直立，花丝上部有疏柔毛，花药狭长圆形，背面有疏柔毛，药隔顶端不突出)组成大叶铁线莲组sect．Tubulosae的原始群——羽叶铁线莲亚组subsect．Pinnatae。而原来的大叶铁线莲C．heracleifolia DC．等种组成此组的进化群——大叶铁线莲亚组subsect．Tubulosae，其特征为花通常单性，萼片直立，雄蕊常有疏柔毛，茎直立，草质至木质。此外，还对C． siamensis Drumm．ex Burkill的4变种和C．connata DC．的5变种进行了分类。(3)描述了3新系、3新种和4新变种。(4)做出了6新组合和3新等级。     

中国石杉属(狭义)小杉兰组的分类学研究

中国荞麦属花粉形态及花被片和果实微形态特征的研究

研究了中国荞麦属Fagopyrum　Mill.的花粉形态、花被片和果实微形态特征。根据沟膜的有无，花粉可以明显地区分为具沟膜者和不具沟膜者2类。透射电镜下显示，荞麦F. esculentum Moench的花粉外壁分化成两个明显的层次，即外壁外层和外壁内层。其外壁外层由覆盖层及柱状层组成，无基层。对花被片腹面的扫描电镜观察表明，根据细胞形状和表面纹饰，这些种类的花被片可分为3类。对果实表面的扫描电镜观察表明，这些种类的果实纹饰也可分为3类。根据上述结果，讨论了荞麦属的种间关系及花粉形态、花被片和果实一些微观性状的演化趋势。荞麦属的花粉形态极为一致，其外壁纹饰均为细网状，萌发孔为三孔沟，这支持将荞麦属从蓼属中分出独立成属的观点。本文还根据花粉形态特征及花被片和果实微形态特征讨论了国产荞麦属的种间关系，探讨了一些特征的演化趋势。     

乌蒙杓兰及其近亲种

 In addition to describing a new species, Cypripedium wumengense, as well as a new variety, C. bardolphianum var. zhongdianense,  nomenclatural and taxonomic notes are made on its allies and the division to which they belong.  They are ltrge]y found in the Hengduan Mountains in southwestern China, characterized by the absence of bract, havirg lip more or less covered with small wart-like outgrowths, and that as the capsule matures the scape becomes much elongated.  Six species of this group have hitherto been reported, of which, however, C. ebracteatum and C. nutans are regarded here as conspecific with C. fargesii and C. bardolphianum respectively. Thus, including the new taxa described here, it composes five species and one variety: C. bardolphianum W. W. Sm. et Farrer (var. bardolphianum and var. zhongdianense S. C. Chen), C. mic- ranthum Franch., C. fargesii Franch., C. margaritaceum Franch. and C. wumengense S. C. Chen.  They are all grouped here into the same section, Sect.  Trigonopedium (Franch.) Pfitz., the oldest legitimate name of this group in the rank of section.

三种贝母核型的比较研究

The present paper deals with a comparative karyotypic study of three species in Fri- tillaria-F. thuncergii Miq., F. anhuiensis S.  . Chen et S. F. Yin and F. hupehensis Hsiao et K. C. Hsia.  The karyotype of F. anhuiensis S. C. Chen et S. F. Yin is first reported.       The karyotypes of the three species of Fritillaria are rather similar, all with K(2n)=24= 2m+2sm+12t+4st+4m (SAT), showing a close interspecific relationship.  They all have two pairs of st chromosomes, one of which is the third chromosome in all the three species studied, but the other is the seventh in F. thunbergii Miq, the eighth in F. anhuiensis S. C. Chen et S. F. Yin, and the fifth in F. hupehensis Hsiao et K. C. Hsia.  It tells us that there are some differences in their karyotypes.  All of the three species possess two pairs of satellite chromosomes with the satellites located on the long arms. A heterochromatic zone is found sometimes on long arms of No. IX chromosome in each species of Fritillaria and on one of No. I chromosomes in both F. thun- bergii Miq. and F. anhuiensis S. C. Chen et S. F. Yin, a chromosome polymorphism occurring between populations of Fritillaria. In addition, three B chromosomes are always found in most root-tip cells of F. hupehensis Hsiao et K. C. Hsiao.
