---|---|---|
W. J. Sando 1983 | Stelechophyllum? with corallite diameter 3.5 to 4.4 mm and 12 to 15 major septa of variable length that may or may not join the columella and may or may not extend into the dissepimentarium. Minor septa ab-sent to well developed. Columella weakly developed (or discontinuous) to strongly developed. Dissepimentarium composed of 1 to 3 rows of small to large inflated dissepiments. Axial tabulae flat to tent-shaped, depend-ing on strength of columella, spaced 2 in 1 mm Peripheral tabellae absent to poorly developed. Ratio of tabularium width to corallite diameter about 0.5. In-crease is peripheral. |
