C. W. Merriam 1972 | Trochoid Streptelasmatinae with solid bladelike axial structure occupying center of inverted bell-shaped calice; transverse outline of calice rim broadly ovoid, nonangulate. Weak fossula in line with median plane of axial rod. Major septa dilated, extend to columella in early adult and younger growth stages; minor septa short. Septal stereozone narrow to moderately wide. Tabulae largely suppressed by stereoplasmic thickening. | |
C. W. Merriam 1973 | Small solitary rugose corals of trochoid shape with solid bladelike axial structure projecting up- ward in bell-shaped calice; transverse outline of calice rim broadly ovoidal and nonangulate. Fossula in line with median plane of axial structure. Major septa project axial- ly to columella in early adult and younger growth stages. Minor septa short; major septa dilated. Septal stereozone narrow. Tabulae largely suppressed by septal thickening. Dissepiments absent. |
