| 摘 要： | 本文是在以经典的比较形态学和解剖学的方法对国产米仔兰族植物分类研究的基础上,运用数值分类方法对中国米仔兰族4属10种植物的分类作进一步探讨。每个运算分类单位(OTU)选用30个性状,进行多态编码,然后采用平均欧氏距离公式和UPGMA公式进行聚类运算。数值分类的结果为中国米仔兰族隶下的几个属的划分,尤其是椤木属Amoora的独立,提供了新的依据;并对大叶山椤提出新的组合:Aphanamixis polystachya(Wall.)R.N.Parker var.grandifolia(BL.)X.M.Chen,comb.nov.

| Abstract: | In this paper, 10 species representing 4 genera of Trib. Aglaieae from China were studied by means of numerical taxonomic methods. Thirty morphological characters were used. The distance coefficients were computed by standized data. Based upon these, the UPGMA clustering method was performed and its results were shown in the form of dendrograms.By means of numerical methods the following taxonomic treatments, relating to the data obtained from morphological and anatomical researches, are proposed. (1) The genus Amoora Roxb. should not be combined with the genus Aglaia Lour. , but kept as an independent one, (2) A phanamixis grandifolia B1. =A.polystachya (Wall. ) R.N.Parker var. grandifolia (B1. ) X. M. Chen,comb. nov. ;(3)Aphanamixis sinensis How et T. Chen should be considered a separate species. |
