Commentaire : Corallum free-living. Each coral with usually one, centrally located mouth (monostomatous). Outline of the corallum from round to oval (in unbroken spcimens). Corallum relatively thick. The length of the central fossa, measured at its bottom, is 1/9 to 1/4 of the coral length. Corallum maximum diameter generally < 15 cm. The septa of lower order cycles are high, thick and solid, flanked by those of higher orders, which are thinner, lower and very often perforated. Septal dentations fine (>10/cm). Corallum wall solid. Costae fine, equal to subequal in size. They are straight and prominent near the corallum margin.. The costae are ornamented with granular, small spines. Granulations on septal fringe predominantly arranged in rows, perpendicular to septal margin.
