The pollen samples of Piper kadsura Ohwi collected from differenthabitats were studied with a scanning electron microscope(SEM). It was found thatthe pollen of P kadsura Ohwi was polytypic, which included boat shaped sulcatepollen grains (about 43.6-57.1%), oblate macroulcerate pollen grains (about38.6 - 46.3%) and tricolpoid pollen grains (about 4.3- 10.1%). Previously, the lattertwo were mistaken for inaperturate and trichotomosulcate pollen grains under opticmicroscope.
