Commentaire : Corallum free-living. Each coral with several mouths. Polystomatism is principally achieved by budding inside the axial groove. The lateral secondary mouths will appear in irregular rows parallel to the axial furrow. The corallum outline varies from elliptical to elongate, with tapering or rounded ends. The coralla are thick and vary from flat to highly arched. Maximum length of the coralla up to 65 cm. The septa are densely packed and straight. Septa of lower order cycles are thick and solid, those of higher orders thin and perforated. The septa of lower orders are more protruding than those of higher orders. The septal margins are coarsely ornamented with irregularly angular and sharp dentations. Their number varies from 15 to 35 per cm. The corallum wall is perforated. It is not covered with granulations. The costae are straight and almost equal in size. All costae are finely to coarsely ornamented with spines which are either blunt and granular at the tips or elongate with acute points.
