---|---|---|
E. C. Stumm 1963 | Corallum simple, conical ranging from 2 to 3 cm long and with a maximum diameter of about 2 cm. Exterior relatively smooth with faint, closely set annulations visible in some areas. Major septa averaging about 40 of which the protosepta prominent, the cardinal long, lying in a long narrow fossula, the alars typically elevated above the metasepta, and the counter well developed, typically at the elevation of the metasepta. All major septa extending to axis near the base of some coralla but as far as 9 mm above the base in others. Major septa denticulate, formed of fused spines, and thickened around the base of each spine. Minor septa appearing near margin of calyx, composed of short rows of spinules. In longitudinal section of specimens with septa reaching axis above base of calyx only the spinose stereoplasm of the septa visible. No trace of tabulae present. |
