Abstract: Xinjiang Uygur Autonomous Region is the largest in area among all the province-level administrative regions of China. It is situated in the hinterland of Eurasian continent and is under the control of a typical extratropical belt continental climate. Algae are very abundant in this region, but the research of algae flora is relatively weak. Algae samples were collected from Xinjiang during the period of July to August, 2001. Samples were preserved with 4% formalin and kept in the Herbarium of the Biology Department of Shanghai Normal University. Microscope slides were prepared by acid digestion method and mounted in Canada balsam or Hyrax gum. Light microscope observations were conducted using a Nikon E-800 DIC microscope at magnification x 1000 and a Nikon digital cameral DXM1200. In the identification, seven species of Navicula (Bacillariophyta) are new records of China, and they are Navicula capitatoradiata Germain, N. digitoradiata (Gregory) Ralfs, N. reichardtiana Lange-Bertalot, N. spicula (Hickie) Cleve, N. subplacentula Hustedt, N. trivialis LangeBertalot and N. upsaliensis (Grunow) Peragallo. Their taxonomic characters and habitats were described.
