Commentaire : Corallum free-living. Each coral with several mouths. The corals are usually elongate with ends varying from tapering to rounded. The coralla vary from slightly to strongly arched. Maximum length of the coralla up to 40 cm. The septa are relatively short because they are interrupted by stomata formed by circumstomadaeal budding. Near the stomata, the ends of the interstomatous septa may be fused with adjacent septa. Adjacent septa are oriented in rows parallel to the central axis. The septa are densely packed and straight. Those of lower orders are thick and exsert, while those of higher orders are thin and low. Septal margins present irregularly angular or lobed dentations. Their number varies from 15 to 25 per cm. The corallum wall is perforated. It is not covered by granulations. The costae are indistinct and finely ornamented. The costal spines are either short and granulated or spinose.
