I know something about Watermelon.It is the fruit and plant of a vine-like herb originally from southern Africa. This flowering plant bears an accessory fruit of a type that botanists call a false berry. The watermelon fruit, loosely considered a type of melon, has a smooth exterior rind and a juicy, sweet, usually red interior flesh. The species descriptor Citrullus vulgaris is sometimes, synonymously, used to refer to this plant.
