Abstract:Pollen morphology of 6 species in the Sect. Theopsis of Camellia were observed under SEM. Pollen grains of the species studied are prolate in shape, elongated-elliptical in equatorial view and trilete rounded (trilete obtuse-triangular for C. euryoides and C. parvicaudata) in polar view, ca. 92.3-106.8 μm × 45.2-58.6 μm in size with apecture 3-colpate, furrow membrane absent or not obvious. Four types of sculptures can be recognized: (1) exine rugulate (Camellia subacutissima Chang and C. handelii Sealy), (2) exine irregularly reticulate(C. fraternal Hance and C. septempetala Chang et L．L．Qi)，(3) exine cerebroid(C. euryoides Lindl.)and (4) exine foveolate(C. parvicaudata Chang)．The features in species studied will serve as good taxonomic characters.
