Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. W. Merriam 1974 | Zonophyllum has a peripheral wreath of thick septal crests in the dissepimentarium and small very steep outer dissepiments. For part of the septal wreath, thick crests are joined discontinuously in a general stereoplasmic mass. The tabularium is occupied by large axially inclined tabellae and rather widely spaced tabulae which are, for the most part, distally convex. |
