[Objective]The aim was to provid taxonomic for identifying Eructus rutaccarpa(Juss.)Beach and its variety E.rutaccarpa (Juss.)Beath.var.officinatis(Dode).[Method]Pollen morphology of wikl E. rutaccarpa and E.rutaccarpa var.officinalis was examined by scanning electron microscope.[Rethod]Pollen of E.rutaccarpa and its variety showed no meaningful difference in shape and structulr,the number of germinal furrow and the surface sculptures, but difference in shape of germinal furrow and depth of vein eyelet were detected. [Conclusion ] The difference offered an effective identification basis for the distinguish of E. rutaccarpa and its variety.%[目的]为鉴别芸香科吴莱萸[Fructus rutaecarpa(Juss.)Benth]及其变种石虎[E.rutaecarpa(Juss.)Benth.vat.officinalis(Dode)]提供分类学依据.[方法]利用扫描电子显微镜时吴茱萸及其变种石虎的花粉形态进行了比较研究.[结果]吴莱萸和石虎花粉的形态结构、萌发沟数和表面纹饰基本一致,但萌发沟形态、外壁网眼的深度等有差异.[结论]这些差异可作为区分昊莱萸与石虎的孢粉学分类和品种鉴定依据.
