Abstract: The genera of Ferula and Heracleum both are very important pharmaceutical plant of Umbelliferae. 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. The pollen pictures of Ferula and Heracleum are taken under optical microscope and scan electrical microscope (SEM), respectively. The results show that the pollen forms of Ferula and Heracleum are prolate and perprolate, respectively, and there are 3 colporates with reticulate sculpture on the pollen exines of the both genuses. The average lengths of polar axis (L) of Ferula and Heracleum are 29.67 and 34.07μm in which there are significant difference by rank-sum test, but the average width of equatorial axis (W) are 17.07 and 15.65μm in which there are no significant difference, furthermore, the L/W are 1.76and 2.19 in which there are significant difference.
