Abstract

Abstract A new marine phytoflagellate is described by means of light and electron microscopy. Clonal cultures were established from sea water samples collected in June 1989 in the vicinity of Igloolik Island, northern Foxe Basin, Northwest Territories, Canada. It was observed again when visiting Igloolik Island in June 1992. Cells are radially symmetrical, 6–8 μm long and 7–10 μm wide, with a single projecting flagellum inserted in an apical depression. The flagellum bears two rows of tripartite flagellar hairs but lacks flagellar scales. A trailing stalk is present at the posterior end of some cells but appears to be missing in others. The cell body is covered by flat oval scales with a slightly thickened marginal rim. Body scales are composed of fibres forming a fine but irregular network. Cells possess six parietal chloroplasts without pyrenoids. The cytoskeleton consists of microtubular triads originating on the surface of the nuclear envelope. Triads were not observed to emanate into tentacles. Anter...
