Tabellaria


A diatom forming flat zig-zag filaments as illustrated, or else radial colonies like those of Asterionella (76). The characteristic septa extend part way across of cells in girdle view and show up as heavy lines. Length of cells, up to 100 pm or more. 71 a. part of a zig-zag chain of cells, held together by mucilage pads, in girdle view. The brown chloroplasts have only been drawn in the upper cell. 71 b. valve view of one of these cells. More common in the less calcareous waters of the north and west.
