| 1. | Plant endemism is the key problem in floristic study . analysis of endemism in a flora has significant implications in demonstrating floristic richness and diversity , the relationship between plants and their environment , and also in conserving biodiversity of the flora . in view of the situation that most of the past studies on endemism were qualitative , this study is the first tentative approach to the introduction of quantitative indices to the analysis of floristic endemism , with an purpose to push the study of endemism from qualitative to quantitative . four quantitative indices are introduced , i . e . level of endemism ( l ) , coefficient of endemism ( c ) , degree of endemism ( d ) and general index of endemism ( a ) . mathematical formulae have been given to each of the above indices and explanations for them have been presented , and the scope of their use in floristic studies has been delimited and exemplified in this paper . the result shows that they are of good applicability . the proposed indices embody full information of plant systematics and plant geography . with the aid of qualitative analysis , the application of the proposed indices will improve the comparability and precision of endemism study in floristics
过去有关特有现象的研究主要限于定性的分析，可比性和精确性较差.该文尝试引入特有现象的定量化指标，以推动特有现象的分析研究从定性水平向定量水平迈进.所引入的4种定量化指标分别是：特有水平、特有系数、特有度以及特有综合指数.对每种量化指标都给出了数学表达式，说明了其区系学意义，例证和界定了这些指标在植物区系分析中的应用，结果表明，它们有良好的适用性.这些指标充分地包含了植物系统学和植物区系学的信息.结合定性分析，这些指标的应用将增强植物区系研究的可比性，使植物区系特有现象的分析达到更精确的水平 | | 2. | The aim of this work is to have a better understanding of the structure , differentiation and phylogenetic relationship of the tribe hyoscyameae in the solanaceae using evidence from leaf epidermis , seed morphology , palynology , embryology , floral organogenesis , trnl - f and its sequences , and plant geography . the results are summarized as follows : 1 . leaf epidermis leaf epidermis of 21 species in seven genera of the tribe hyoscyameae and four species in four related genera was investigated under both light microscope ( lm ) and scanning electron microscope ( sem )
解剖学在光学显微镜和扫描电镜下，观察了茄科天仙子族( hyoscyameae ) 7属21种及邻近4属4种共25种植物的叶表皮特征，结果表明：气孔器在各种植物的上、下的表皮均有分布，多为无规则型，也有不等细胞型；叶表皮细胞形状有不规则形、十字形、近长圆形和不规则多边形，垂周壁较平直或各种波状。 | | 3. | In the 25 species examined , the epidermal cells fall into four types in terms of their shape and the pattern of the anticlinal wal ls . these types correlate to some extent with features of gross morphology , palynology and plant geography of the ten genera studied . features of cuticular membrane can be used to differentiate clearly the two genera physochlaina and hyoscyamus , and some species within them
颠茄叶表皮细胞形状和垂周壁式样在一些属和种中有一定的规律性，并与外部形态、孢粉学性状或地理分布相关；叶片表面角质膜的特征对属和种的划分也有一定意义。 |
