Synangia arranged in two rows along midvein of fertile pinnule, on its abaxial surface. Spores round, trilete. Rays of trilete scar occupying two-thirds of spore radius. Sporoderm covered by fine scabrate ornamentation.


From the Latin convexus (convex), based on the convex ornamentation of the synangia.
