Commentaire : Corallum free-living. Each coral with several mouths. They are irregularly oval with their ends varying from tapering to rounded. The coralla vary from thin to thick and from flat to highly arched. In specimens not yet fullgrown, the secondary stomata are usually concentrated around the distinctly larger, centrally located primary stoma. In large specimens new stomata become distributed more evenly over the whole corallum surface. Maximum length of the coralla up to 35 cm. The septa are densely packed and usually straight, except around the stomata and near the corallum margin, where they may bend slightly. The septa are of unequal thickness and height. The septal margins are coarsely ornamented with irregularly serrate, long dentations. The corallum wall is perforated and covered by granulations. "The costae are unequal; they are straight and distinct near the corallum margin, less distinct near the centre. " All costae are coarsely ornamented. The costal spines are either short and covered by some granulations or long and echinose.
