Abstract: Pollen morphology of 34 species (including 2 varieties)representing 17 sections of Camellia was examined under light microscope (LM)and scanning electronic micrscope (SEM)in this paper.The pollen grains are classified according,to the standard of Wei Zhongxin, they belonging to 3 types: granulate to rugulate-granulate,rugulate-fossulate,foveolate- reticulate.A new pollen type,i.e.false fpveplate-re-ticulate ,was found and named. Generally speaking,the sculpture difference of various sections is not nec-essarliy larger than that of the same section,for example,in section paracamellia, the sculpture varies very much from rugulate-fossulate to false foveolate-reticulate,and then to foveolate-reticulate.Showing that it is difficult to elucidate the sustematical relationships detween different sections dy the sculpture of pollen exine surface.Some classification problms of Camellia were probed onto preliminarily too.
