Types

Original diagnosis/description

As for the genus with the following additions: Fruit elliptical to circular in lateral view. Surface of fruit slightly rugulate. Seeds three. Mesotesta thicker than the endotesta. Mesotesta one cell layer thick; cells palisade shaped of uneven height resulting in a rugulate surface, anticlinal walls not undulate. Endoreticulate infillings of endotesta cells weakly developed. Endotesta without interspersed cavities. Endotestal cells fibrous. Ovular vascular bundle between mesotesta and endotesta. Testa surrounding micropyle not swollen.

Etymology

Fromthe wavy-rugulate surface of the mesotesta in the contact regions between two seeds (Latin undatus [wavy].
