Abstract: Pollen grains of 32 species of the genus Viola in China were examined under LM and SEM. Their morphological characters are described here. Pollen morphological characters under LM are similar except V. tricolor L. under SEM, the exine of pollen have some difference among the four subgenus of Viola. The evidence from pollen morphological characters supports Juzepchuk's (1949) and Wang Qing-rui's (1991) treatments which divided the Viola into four subgenus.

Key words: Viola, Pollen morphology
