Abstract: The pollen morphology of 8 species and 2 varieties of the Tribe Brassiceae from China and other countries was examined under LM and SEM. 4 speces and 2 varieties were palynologically reported here for the first time. The results showed that the pollen morphology of the Brassiceae above-mentioned was consistent basically, but some difference between them in pollen size, aperture (Crambe abyssinica, 4-colpate) and eaine sculpture was found. The present paper also found that the pollen size of these species might have certain correlationship with their chromosome numbers.
