Fruits of Mauritius - Watouk

I recently heard about an obscure fruit from Mauritius called Watouk. After asking for help, I got this from Bashdev: "Watouk also known as clidemia hirta produces berries. Called locally as fraise lolou"

An RCPL74 friend found a paper about the plant. I believe you get it around Plaine Champaigne - where we get goyaves de Chine.
