Axial corallites : Usually not well defined on branch tips eXcept plate’s margins where there may be more than one; they are tubular with round opening and thick wall; primary septa are conspicuous, but second cycle absent. Radial corallites : Wide variety of shapes and sizes; they may be exsert or sub-immersed; tubular, nariform or tubular appressed with round or dimidiate openings; radials are usually crowded and tend to be shorter or sub-immersed on the underside of branches; primary septa may be visible as points on longer corallites, but secondary septa are absent. Coenosteum : Costate on radial corallites occasionally dense rows of simples spinules; reticulate with scattered spinules between corallites.
