Identification difficulty
ID checklist (your specimen should have all of these features)

Ripe fruits are essential for identification; this plant cannot be verified from photos of the plant or flowers. 

Calyx present in fruit (unlike V locusta and dentata); and toothed, usually with 2 or more distinct teeth. Fruit has two distinct ribs on the abaxial face delimiting an oval flat area
