Original diagnosis/description

As for the genus with the following additions: Seeds elliptic in lateral view, broadest at around the midpoint, almost circular in transverse section. Hilum and micropyle borne on a small raised area. Hilum almost circular, lacking a prominent rim. Palisade cells of exotesta are tall. Facets of exotesta cells equiaxial, irregularly aligned over most of the seed surface; folds of anticlinal walls rounded. Exotestal tissue between hilum and micropyle narrow and curved in longitudinal section.


The species is named for the State of Virginia, USA, in which the Puddledock locality is located.
