Valve view of the pennate diatom, Cymatopleura solea (Brébisson) W. Smith 1851. Valves are elliptical with a central waist and bluntly pointed apices. The valve surface is marked with several transverse undulations best seen in girdle view; striae and undulations are not interrupted in the median axis. Raphe are marginal. Very short costations appear as beading around the edge of the valve. There is a single lobulated plastid one half of which lies along the inner surface of the epivalve and the other along the inner surface of the hypovalve. Collected from the benthos of a freshwater pond near Boise, Idaho, January 2005. DIC.
