| 摘 要： | 报道了山东胡枝子属（Lespedeza Michx.）7种植物花粉的亚显微形态特征，花粉粒从赤道面观呈近长球形，极面观呈三裂圆形，具三条萌发沟；表面纹饰均为网状；花粉粒大小极轴长为26．3－19．0μm，赤道轴宽约为21．7－8．6μm研究结果表明，胡枝子属花粉的形态结构特征支持传统分类中的属和种级水平的分类。

| Abstract: | The pollen morphology of 7 species in the genus Lespedeza Michx. from Shandong was examined by light microscope and scanning electron microscope (SEM). The pollen grains of the genus are subproblate in equatorial view, 3 - labed - runded, and 3 - eolparate in polar view; the exine scupture is with reticulate, the polar axis of the pollen grains is 19.6～26.3 μm, and the equatorial axis is 8.6～21.7μm. The results are that the pollen morpholcgy characteristic of Lespedeza Michx. is in support of the genus and species class for classic taxonomic. |
