- Diagnosis
- Pollen with 10 to 20 lumina per 100 µm2 at central distal face, elliptic to polygonal lumina; nanogemmae free-standing columellae extremely rare and singular; opercula with a reticulate supra-layer. All other pollen features that can be observed under LM and SEM comparable to that observed in two of the modern species: Sclerosperma mannii and S. walkeri.
