Portrait of Phacus suecicus, a leaf-shaped euglenoid flagellate. The body is strongly flattened with a broadly rounded anterior and a curved acuminate caudus. A single flagellum emerges from an anterior median papilla-like protuberance. The flagellum is about 1 and a half times the cell length. The pellicle is ornamented with longitudinal rows of knob-like projections which converge somewhat at the anterior and posterior ends of the cell. There is a prominent anterior stigma. The numerous green chloroplasts are small and discoid. The paramylon is massed in two to four parietal plates. The central nucleus is not seen in this image. Probably synonymous with P. monilata. From polysaprobic standing freshwater pool in a low mountain grass meadow near Boise, Idaho. Differential interference contrast. This image was taken by William Bourland. He now uses a Zeiss Axioskop 2 with Spot Insight and Spot Flex CCD cameras (Diagnostic Instruments). Image copyright: William Bourland, image used under license to MBL (micro*scope).
