由BioPedia提供
Cells contain numerous yellow-brown chloroplasts. Dorso-ventrally flattened cells with open horns. The epitheca is asymmetric, with rounded left and steep right side, leading gradually into an anterior horn, directed to the right. The hypotheca is extending into two antapical horns at its posterior edges. They are directed anteriorly. The right horn usually longer than the left one. Difficult to distinguish from C. horridum! Thick thecal plates are ornamented with reticulations and the horns can be toothed. Plates in the central area on the ventral side are very delicate. The nucleus is situated in the epicone.
