Abstract: In order to clarify the differences among pollens of Isodon amethystoides, I.Macrocalyx and I.nervosa, the pollens of 8 different populations from these three species were observed by scanning electron microscope.The main results are as follows:Although similar on the whole, the pollens from different populations are of difference on their aperture, the size, and the ornamentation of exine, the number of the holes and the reticulations etc.There are many differences among the pollens of the plants of these three species (Isodon)on the morphology, the size, the aperture.The differences on surface of pollens provide a new evidence for specific identification of the genus.

Key words: Isodon, pollen, scanning electron microscope
