Original diagnosis/description

As for the genus with the following additions: Seeds elliptic in lateral view and broadly elliptic in transverse section. Hilum and micropyle area not raised. Hilum circular in outline with an indistinct rim. Palisade cells of exotesta short. Facets of exotesta cells transversely elongate, aligned in longitudinal rows over most of the seed surface; folds of anticlinal walls sharp. Exotestal tissue between hilum and micropyle curved in longitudinal section.


The species is named for the town of Hopewell, Virginia, USA, close to the Puddledock locality.
