FIGURE 3. Corymorpha balssi Stechow, 1932, preserved specimens. A. Hydranth. B. Hydrocaulus. C. Detail of the upper, naked part of caulus, showing nematocyst clusters on epidermis and longitudinal, endodermal ridges. D. Junction between the upper and lower parts of caulus. E. More detailed view of the junction, showing distinct groove, as well as the presence of nematocyst clusters in the upper part, and their absence from the lower part. F. Cross-section through the upper part of caulus, to show the presence of endodermal ridges. Scale bars: E = 100 µm; C, D, F = 200 µm; A, B = 500 µm.
