| W. J. Sando 1983 | Petalaxis with corallite diameter 3 to 4.5 mm and 14 to 16 major septa that closely approach the columella but seldom ยท reach it and extend into the dissepimentarium, ordinarily being attached to the cor-allite wall. Minor septa ordinarily well developed. Col-umella a simple axial plate connected to counter or car-dinal septum. Dissepimentarium weakly lonsdaleoid, composed of a single row of small inflated dissepiments. Tabulae complete or incomplete, essentially horizontal, mostly concave, and spaced 0.5 to 1 mm apart. Ratio of tabularium width to corallite diameter about 0. 7 to 0.8. Increase peripheral. |
