Textual Research on Chinese Mangrove Bruguiera cylindrica( Rhizophoraceae)

1927年MErrIll首次报道海南产柱果木榄。通过对MErrIll引证的标本进行研究,发现所谓的柱果木榄是MErrIll的错误鉴定,确认该标本是海莲。中国不产柱果木榄,先前有关该种的研究结果需要更正。Bruguiera cylindrica was first reported from Haikou in China by Merrill in 1927.The specimen cited by Merrill was researched carefully and the result reveals that the so called Bruguiera cylindrica is only a mistaken identification by Merrill.This specimen is Bruguiera sexangula.So Bruguiera cylindrica is not distributed to China and the foregone research results of this species should be revised.国家自然科学基金面上项目(31270234);国家自然科学基金(31110103911); 中国科学院知识创新工程(KSCX2-EW-Z-1

A note on a mangrove Acanthus xiamenensis (Acanthaceae)

重新检查了厦门老鼠簕的主模式和副模式标本后,发现原始文献对其鉴别特征"花……具两个苞片,无小苞片"描述有误,应改为"花……具两个小苞片,一个苞片"。基于标本室和野外观察,认为厦门老鼠簕在老鼠簕的正常变化范围之内,应归并到老鼠簕;不赞同把厦门老鼠簕降级为小花老鼠簕或毛鼠簕的变种的处理。报道了一个新异名Acanthusilici folius var.xiamenensis。After the holotype and paratypes of Acanthus xiamenensis had been rechecked,the author found the diagnostic character "foliis……bracteis 2 oppositis instractis ebracteolatis" was wrongly described in original paper,and it should be revised as "foliis……bracteis 1,bracteolatis 2 oppositis".Basing on herbaria and field observations,the authors argue that A.xiamenensis was fallen to the varieties of A.ilicifolius,and should be reduced to A.ilicifolius,and did not agree to the treatment that A.xiamenensis was degraded into a variety of A.ebracteatus or A.ilicifolius.A new synonym Acanthus ilicifolius var.xiamenensis was reported.厦门大学科技创新项目(XDKJCX20041019)~

Comparative anatomy on leaves of Fissistigma (Annonaceae) from China

采用叶片表皮离析法、扫描电镜和石蜡制片法,研究了中国分布的番荔枝科瓜馥木属19种植物叶片的形态结构。结果表明:瓜馥木属叶片形态和结构具有较多的相; 似性,如叶片表皮均具有2-多个细胞的单列丝状毛,表皮细胞内具有一个晶簇,气孔器均为平列型,只分布在叶片的远轴面,远轴面的表皮细胞平周壁形成一个乳; 突,叶片主脉的维管组织除具有正常的维管组织外,还具有一个小的副维管束等,这些特征有助于区分番荔枝科植物的属间关系,支持瓜馥木属是一个很自然的类群; 。但叶片表皮毛的形态及分布,表皮细胞的形状、叶肉中栅栏组织和海绵组织的结构、远轴面的乳突大小以及叶主脉维管组织的细微结构则具有种间差异。尤其有助; 于区分小萼瓜馥木和黑风藤、广西瓜馥木和独山瓜馥木、上思瓜馥木和东方瓜馥木等形态相似、难以区分的植物种类。该研究结果为该属的系统研究和种间正确区分; 提供了重要资料。Leaf morphology and structures of nineteen species of Fissistigma from; China were studied using epidermal maceration,scanning electron; microscope and paraffin section method. The results showed that the; anatomical feathers of Fissistigma revealed a remarkable consistency.; The leaf surface of Fissistigma were covered with bicellulate or; multicellulate uniseriate trichomes. The epidermal cells contained one; clustered crystal. The stomatal apparatus were paracytic with two to; four subsidiary cells and only distributed on abaxial epidermis. The; outer percilinal walls of abaxial epidermal cells were papllate. In the; leaf midrib,there was one additional vascular strand except for normal; vascular tissues. Therefore, these anatomical feathers should be; contributed to differentiate the relationship among genera and support; that Fissistigma is a natural group in Annonaceae. However,the form and; distribution of trichomes,the shape of epidermal cells,the structures of; mesophyll tissues,the sizes of papllate cells and the precise vascular; structures in midrib vary obviously with species. Also,these anatomical; differences between species may be used to distinguish some perplexing; species such as F. minuticalyx and F. polyanthum,F. kwangsiense and F.; cavaleriei,F. tungfangense and F. shangtzeense.国家自然科学基

Analysis of the Contradictions of Keys and Its Significance in Practice

通过对生物检索表结构的分析,认为检索表的根本矛盾是标本具有的个性性状与检索表使用的共性性状的矛盾。单道检索表的主要矛盾是检索表对性状的有条件使用与单个标本性状有限性之间的矛盾,因而单道检索表未能很好地解决其基本矛盾,使得其应用范围和使用效果受到诸多影响。多道检索表的主要矛盾是性状数据库内性状的有限性与物种具有的个性性状的无限性之间的矛盾,不存在个性与共性的矛盾,即解决了根本矛盾问题,便于检索应用。Based on analysis of the structure of keys, this paper deems that the fundamental contradiction of keys is the contradiction between the individual characters of specimens and the common characters used in keys.The principal contradiction of single-access key is the contradiction between the characters used conditionally in keys and the finite characters of individual specimens, so single-access key cannot well solve the fundamental contradiction and is limited in applicative areas and on using effect.The principal contradiction of multi-access key is a contradiction between the limited characters of character database and the unlimited individual characters of species, hence there is not the contradiction between individual characters and the common characters.Therefore, multi-access key well resolves the fundamental contradiction and can be utilized expediently.国家自然科学基金(31270234); 厦门大学科研基本业务费项目(2010121089

中国罗汉松属叶角质层微形态结构及其分类意义

利用扫描电镜对罗汉松属8种2变种植物叶角质层内外表面进行了细致观察。发现罗汉松属植物叶角质层结构具有许多相似特征,表皮细胞较为规则,长方形或多边形,边缘波状弯曲;气孔器排列成带状,长轴均与叶脉一致,气孔器具较为明显的气孔塞和伏罗林环,气孔器保卫细胞极延伸明显,通常具有2～4个副卫细胞、不具极副卫细胞。但罗汉松属叶角质层结构也具有明显的种间差异,镰叶罗汉松和洛杉矶罗汉松同其它种类差异最大,这两种植物叶两面均具气孔器,角质层内表面垂周壁直,角质层凸缘不明显;贺氏罗汉松最为显著的特征是近轴面和远轴面表皮细胞的垂周壁角质层厚且凸缘均极其发达;小叶罗汉松近轴面表皮细胞排列较为规则,多数为方形,长轴与叶脉垂直,垂周壁之间的角质层突起较为显著,延伸到皮下层;兰屿罗汉松近轴面表皮细胞排列较不规则,多边形,细胞的角端比较钝,没有棱角;大理罗汉松气孔带间隔较小,有时两条气孔带挤在一起,使副卫细胞紧连,近轴面表皮细胞较短,方形或长方形,垂周壁之间的角质层较不发达;海南罗汉松角质层气孔带间隔较宽,气孔器形状为阔椭圆形,近轴面表皮细胞均为细长方形;变种短叶罗汉松和狭叶罗汉松与罗汉松也具有明显差异,短叶罗汉松近轴面表皮细胞排列不规则,垂周壁深波状弯曲,凸缘极为明显,但原种罗汉松近轴面表皮细胞排列较为规则,垂周壁浅波状弯曲,凸缘不明显,而狭叶罗汉松近轴面表皮细胞方形或长方形,比罗汉松的表皮细胞短,垂周壁直或略弯曲,角质层极厚。这些角质层微形态特征差异可以作为罗汉松属内种类分类鉴定的依据。江苏省高校自然科学基础研究项目(06KJD180201)~

福建邵武将石地区维管束植物区系分析

福建邵武将石地区的植物区系处于泛北极植物区,中国-日本森林植物亚区的华东地区,有维管束植物173科461属915种(含种下单位).该区植物种类丰富,具有许多珍稀、古老、孑遗植物成分.在科、属水平上对其区系特征进行了分析,结果表明:热带分布类型的科占绝对优势,共77科,占53.1%;温带分布类型有37科,占25.5%;属的区系成分中,属的热带分布类型计197属,占区总属数的52.2%,温带分布类型共有169属,占44.9%.可见该植物区系的热带、亚热带成分占主导地位,温带成分次之.聚类分析结果表明该地区种子植物区系成分和庐山自然保护区关系最为密切,鼎湖山自然保护区次之,和五台山自然保护区的差异较大,这主要由它们生态地理条件、区系成分组成的差异所决定
