山矾科中原氏山矾复合体的叶形态特征及分类意义

摘要

Based on morphology and statistical analysis, we studied the morphological structure of Symplocos nakaharae complex ( Symplocaceae). The results showed that leaf texture in this complex can be divided into leathery and papery. Leaf size varied differently, S. kawakamii, S.tetragona, and S. henryi were significantly different from others, and the variation of the rest were continuous. These characteristics could be used to identify species and provide basicdata for the study of taxonomic revision in Symplocos nakaharae complex.%该研究在形态学观察以及统计学分析的基础上,深入研究了山矾科中原氏山矾复合体的叶片形态学结构.结果表明:叶片质地在整个复合体中可分为革质、纸质2种类型,叶片大小变异幅度较大,除中原氏山矾(Symplocos kawakamii)、棱角山矾(S.tetragona)、蒙自山矾(S.henryi)均与其他种差异显著外,其余种均属于连续过度,叶片分形可以初步区分该复合体植物.该研究结果为中原氏山矾复合体的进一步研究提供了依据,对复合体的分类处理具有一定的分类学意义.
