亚洲粗叶木属及相关属植物叶表皮微形态特征

利用光学显微镜和电子扫描显微镜研究了亚洲茜草科粗叶木属植物26种（包括1个亚种和2个变种）和相关4属即巴戟天属、九节属、染木属和尖叶木属6种植物的叶表皮微形态特征。粗叶木属植物上表皮细胞形状一般呈不规则波状、近椭圆形或者不规则多边形,下表皮细胞一般呈不规则皱波状或者多裂深波状,细胞壁曲折无章,细胞间界限不明显,上、下表皮细胞壁均有加厚现象。叶表皮角质层明显,在电镜下有以下几种类型：颗粒状,网状,鳞片状,乳突状。气孔器几乎全部生在下表皮,有些种气孔下陷,气孔器一般是一对保卫细胞和一对副卫细胞平列。一些粗叶木属植物种叶上着生表皮毛。表皮毛分为单细胞毛和单列多细胞毛两种结构类型以及扭曲毛,线形毛和直壁毛3种形态类型。相关属的叶表皮微形态特征与粗叶木属植物较为相似。粗叶木属植物叶表皮微形态特征具有一定的分类学价值,其性状虽有遗传稳定性,但随生态环境不同而有一定变异。粗叶木属植物叶气孔长轴径/径轴变化幅度比较大以及叶表皮上的毛被多样化均能反映其对生态环境的适应变化。     

中国粗叶本属（茜草科）的植物地理研究

本文研究了中国产粗叶木属植物３０种４亚种和７变种的地理分布,划分出三个分布区类型,十二个变型和四个亚变型,根据种多度和分布特征,中国粗叶木属植物在分布上表现出与中国的热带雨林、季雨林区,南亚热带常绿阔叶林带和中亚热带常绿阔叶林带相匹配的分布规律,并受几条植物地理界线的作用。通过对地理替代类群和一些特殊分布式样的分析,显示了所谓的“田中线”和一条北起四川蛾眉向南经贵州西南部至广西醅的界线对粗叶木各的     

东亚粗叶木属(茜草科)植物的分布及其生物地理意义

茜草科粗叶木属植物是亚洲热带原始林下优势地位明显的一类灌木植物.依据标本资料和分类学修订,研究了东亚产粗叶木属植物33个种的地理分布式样,并将其划分为热带亚洲、东亚和中国特有3个分布区类型,其中热带亚洲分布型可以进一步划分为印度(喜马拉雅)至马来西亚分布、印度(喜马拉雅)至中国南部和大陆东南亚分布及中国南部至大陆东南亚分布3个亚型.中国粗叶木属植物中热带亚洲分布型占总种数的72.7%,显示了中国热带地区植物区系的热带亚洲亲缘.一些粗叶木属植物种类的分布式样暗示了中国-日本、中国-喜马拉雅森林植物区系的分区及物种形成,喜马拉雅(横断山)-台湾山地植物区系的联系及台湾-琉球-日本物种迁移通道.海南、台湾植物区系缺少特有种反映了它们的植物区系大陆性很强. 粗叶木属植物种类的分布式样对中国热带植物种分布区类型的划分提供了参考.

A taxonomic revision of the genus Lasianthus Jack. (Rubiaceae) from Thailand

A taxonomic revision of the genus Lasianthus Jack. from Thailand is made based on specimens in BKF, BK, L, AAU, K, BM, E, P, KEP, SING and PSU etc. Three species and three varieties are described as new; a new combination, L. trichophlebus subsp. barbellatus ( Ridley) H. Zhu, is made; eight species and five varieties are found to represent new records to Thailand; seven species, i.e. L. brevidens Craib, L. densifolius Miq., L. incomptus Craib, L. scalaris Craib, L. penicillatus Craib, L. virgatus Craib and L. zambalensis Elmer, axe reduced to synonyms; two species, L. brevipes Craib and L. lowianus King et Gamble are moved to the genus Saprosma; the delimitation of some species is clarified. As a result, fifty-two species, one sub-species and twelve varieties are recognized in the genus Lasianthus from Thailand.     

Four new species and one new record of Lasianthus (Rubiaceae) from Thailand

Four new species of the genus Lasianthus are described from Thailand and accompanied with taxonomic remarks. These new taxa are: L. ellipsoideus, L. flavi-hirtus, L. loeiensis and L roosianus. One variety, L. politus var. insularis is considered to be a synonym of L. coronatus extending the range of this species to Thailand.     

A revision of the genus Lasianthus (Rubiaceae) in Africa, excluding Madagascar

23 species, one subspecies and three varieties have been described or named for the pan-tropical genus Lasianthus Jack (Rubiaceae) in continental Africa. In the present revision thirteen species, five subspecies and one variety are recognized; additionally two hybrids are proposed. Of the previously named taxa, the subspecies is raised to species rank whereas two species are degraded to subspecies and variety status, respectively. Five species are synonymised including two varieties, and four are left with uncertain status, including one variety. The distribution of the genus in Africa consists of two distinct elements: one component is found in the Guineo-Congolian regional centre of endemism and one in the eastern part of Afiomontane Archipelago-like regional centre of endemism. A centre of species diversity is found in Eastern Arc Mts., where six endemic species occur together with L. laxinervis and the more widespread L. kilimandscharicus. Four of the species are strict endemics of the Uluguru Mts. In addition to the presentation of the new section: Lasianthus Sectio Membranacei, sect. nov., this revision contain two hybrids from Uluguru Mts.: L. macrocalyx × pedunculatus and L. cereifizorus × pedunculatus, and following new taxa and new combinations: L. africanus ssp. biokoensis, subsp. nov.; L. africanus ssp. mayumbensis, comb. et stat. nov.; L. kilimandscharicus ssp. glabrescens, ssp. nov.; L. kilimandscharicus ssp. glabrescens var. xanthospermus, comb. et stat. nov.; L. kilimandscharicus ssp. hirsutus, ssp. nov.; L. laxinervis, stat. nov.; L. pedunculatus ssp. angustisepalus, ssp. nov.     

中国粗叶本属（茜草科）的植物地理研究

本文研究了中国产粗叶本属植物３０种４亚种和７变种的地理分布,划分出三个分布区类型,十二个变型和四个亚变型。根据种多度和分布特征,中国粗叶本属植物在分布上表现出与中国的热带雨林、季雨林区,南亚热带常绿阔叶林带和中亚热带常绿阔叶林带相匹配的分布规律,并受几条植物地理界线的作用。通过对地理替代类群和一些特殊分布式样的分析,显示了所谓的“田中线”和一条北起四川峨眉向南经贵州西南部至广西西部的界线对粗叶木种的分布,特别是对中国－喜马拉雅和中国－日本替代分布具有明显的作用。这导致笔者认为“田中线”作为中国－日本分布的西界而另一第线作为中国－喜马拉雅分布的东界。进一步的分析还揭示由云南南部沿缅甸、泰国向南延伸的横断山余脉既充做一条植物南－北迁移的通道又是一条中南半岛西部（印－缅）与东部（印度支那－华南）的植物地理界线。

金盏苣苔属(苦苣苔科)的第二次校订

金盏苣苔属(Isometrum Craib)属于苦苣苔亚科(Cyrtandroideae)长蒴苣苔族(Didymocarpcae),是由W.G.Craib 1919根据I.farreri Craib建立的,同年他又把Didissandra glandulosa Batalin置于该属,1960年B.L.Burtt又把Didi-sandra Clarke中的4个种(即:D.prumuliflora Batalim,D.giraldii Diels,D.fargesii Franch.和D.leucantha Diels)移入该属。作者在编写中国植物志苦苣苔     

The varieties of Bauhinia pottsii G. Don in Thailand (Leguminosae-Caesalpinioideae)

 Bauhinia pottsii G. Don, B. subsessilis Craib, B. velutina (Wall. ex Benth.) Baker, B. mollissima (Wall.) Prain, and B. decipiens Craib were recently recognized as five varieties of Bauhinia pottsii G. Don. They grow naturally in southern Myanmar, Thailand, Indochina and the Malay Peninsula. Bauhinia pottsii var. decipiens (Craib) K. Larsen & S. S. Larsen is endemic to Thailand and known only from the type collection, so it was omitted from this study. Quantitative and qualitative morphological characters were examined in 200 specimens using multivariate and univariate analyses to determine the taxonomic relationship among the four. Some variation in qualitative characters was found between the varieties which separated them as previously defined in Flora of Thailand. Forty-three quantitative characters were subjected to cluster analysis to allow an objective classification into groups. The groups were subsequently evaluated by a canonical discriminant analysis. It was found that these characters collectively support the four varieties as defined by qualitative characters. However, the close relationship of varieties mollissima (Wall. ex Prain) K. Larsen & S. S. Larsen and velutina (Wall. ex Benth.) K. Larsen & S. S. Larsen is observed. The linear discriminant function has an overall rate of 98.5% correct classification and is useful for variety classification. Among quantitative characters, petal-claw length and ovarystalk length together with some qualitative characters are useful for key construction to separate the four varieties.
