Hibiscus surattensis
Hibiscus surattensis, the bush sorrel  or wild sour, is a widespread species of flowering plant in the family Malvaceae. It is native to the seasonally dry tropical (and subtropical) Old World, and has been introduced to many islands of the Indian Ocean. As the common names imply, it is eaten as a leafy green by local peoples. References
