In 19 phytoplankton samples collected from 14 water bodies in the southeastern part of China and examined by electron microscopy, 27 taxa of silica-scaled chrysophytes (8 of them belonging to the Chrysophyceae and 19 to the Synuriphyceae) were found. All these taxa are new to Fujian province;24 of them were previously found in China, but 3, viz. Chrysosphaerella septispina, Mallomonas rasilis and M. guttata var. simplex are new to China. M. guttata var. simplex has only been reported from the Ontario region, Canada. The silica-scaled chrysophyte flora and their geographical distribntion in thisregion are discussed.
