As for the genus with the following additions: Fruit broadly elliptical to circular in lateral view. Surface of fruit smooth. Stigma restricted. Seeds three to four. Mesotesta and endotesta of approximately the same thickness. Mesotesta thin in the contact region between seeds. Mesotesta one cell layer thick; cells cubic with anticlinal walls very thick toward the outside, and thin and undulate toward the inside. Endoreticulate infillings of the endotesta cells dense. Endotesta thick with interspersed cavities (possible oil cells) over most of the seed; endotesta thinner in the contact region between two seeds. Ovular vascular bundle in the endotesta. Testa surrounding micropyle swollen.
From the swollen form of the seeds (Latin grossus [fat, thick]).
