There are different opinions of the taxonomy on the subfamily, tribe, genus and species of Umbelliferae because the taxonomic system of Umbelliferae is based on the typical umbrella anthotaxy and its fruit with specific secretory tube. The pollen morphology is carefully observed in this test in order to provide several basic data for the taxa of Ferula and Heracleum.

但是由于伞形科的分类系统是建立在典型的伞形花序和带有特殊分泌管的果实的基础之上的，使得分类学者在亚科、族、属和种的设立和分类方面存在分歧，实验主要针对阿魏属和独活属的花粉形状进行研究，对阿魏属和独活属植物的分类提供一些基础数据。

The distinctly clavate vittae, shorter than the length of the mericarp, are characteristic of many Heracleum species, but this does not hold for some of the Chinese species.

明显棍棒状的油管，短于分果爿，为许多Heracleum 的种的特征，但一些中国的种不具此特征。

Pollcn morphology of 11 Heracleum species was examined under LM andSEM. It is shown that pollens of these specics are all of retangular type andequatorial constricted type, with polar views of 3-splitted round, obtuse triangle ortrianglc. Interspecific variations exhibit in pollen size and exine exolamelle.

对独活属11种植物的花粉进行光镜和扫描电镜观察发现，本属花粉为伞形科中比较进化的矩形型和赤道收缩型；极面观3裂圆形、钝三角形、三角形；花粉大小及外壁纹饰在种间存在明显差异。
