Original diagnosis/description

As for the genus with the following additions: Fruit broadly elliptical in lateral view. Surface of fruit finely reticulate. Stigma restricted. Seeds two, rarely one. Mesotesta thicker than endotesta. Mesotesta two cell layers thick; cells cubic; cells of inner cell layer with evenly thick cell walls; cells of outer cell layer thin-walled, not undulate. Endoreticulate infillings of endotesta cells dense. Endotestawithout interspersed cavities. Ovular vascular bundle between mesotesta and endotesta. Testa surrounding micropyle slightly swollen. Outer epidermis of tegmen with slightly elongate, thin-walled cells.


From the reticulate surface of the fruits (Latin reticulatus [reticulate]).
