Endotesta much thicker thanmesotesta.Mesotesta one cell layer thick; cells cubic; anticlinal walls very thin and undulate toward the inside and outside, thick in themedian partwith smooth inner surfaces. Endoreticulate infillings of the endotesta cells dense. Endotesta without interspersed cavities. Ovular vascular bundle in endotesta. Testa surrounding micropyle not swollen. Outer epidermis of tegmen with thin-walled, slightly elongate cells.
