Commentaire : Corallum free-living. Each coral with usually one, centrally located mouth (monostomatous). Corallum outline is oval-elongate with rounded ends. The coralla vary in thickness and their shape varies from flat to arched. The length of the central fossa, measured at its bottom, is 1/8 to 1/4 of the corallum length. Maximum length of the coralla up to 25 cm. The septa are more or less loosely packed and straight. The septa of low order cycles are thicker and more protruding than the septa of higher orders. The septal margins are finely to coarsely ornamented with irregularly angular dentations. Their number varies from 12 to 30 per cm. The corallum wall is not granulated and solid in immature specimens and perforated in adults. The costae are almost equal in size; they are straight and distinct from the corallum margin towards the centre. They are finely to coarsely ornamented with blunt, granular spines which may appear to be laterally compressed when fused.
