The cylindrical polyps are situated all around the branches and are up to 1.75 mm long and 1 mm wide. The infolded tentacles contain small, flattened scales, up to 0.10 mm long, sparsely ornamented with simple, rounded projections (Figure 3a). These extend along the tentacle bases and intergrade with longer, more closely sculptured capstans, belted spindles and cylinders densely filling the polyps and coenenchyme, 0.05–0.15 mm long (Figure 3b). A few poorly developed clubs (Figure 3b top) and crosses (Figure 3c) are also ...
