As for the genus with the following additions: Fruit elongate elliptical to circular in lateral view. Surface of fruit smooth to slightly verrucate. Stigma restricted. Seeds one to six. Mesotesta much thicker than endotesta. Mesotesta one cell layer thick; cells palisade shaped with very thick, evenly thickened anticlinal walls; anticlinal walls not undulate andwith smooth inner surfaces. Endoreticulate infillings of the endotesta cells weakly developed. Endotesta without interspersed cavities. Ovular vascular bundle between endotesta and mesotesta. Testa surrounding micropyle not swollen. Outer epidermis of tegmen with narrow, elongate fibers with reticulate thickenings.
