| C. W. Merriam 1972 | Solitary rugose corals with wedge-tapering lamellar major septa, short to very short minor septa, and a well-developed septal stereozone. Septa thickened ontogenetically to later neanic growth stage and laterally in contact, thereafter thinning progressively from axis toward periphery. Tabulae and tabellae irregularly arched, obscured by stereoplasmic thickenings. No dissepiments. Fossula weak or lacking |
