Citrullus lanatus

The watermelon (Citrullus lanatus) is a species of flowering plant in the family Cucurbitaceae, that has a large, edible fruit. It is a scrambling and trailing vine-like plant, and is widely cultivated worldwide, with more than 1,000 varieties. Watermelons are grown in favorable climates from tropical to temperate regions worldwide for its large edible fruit, which is a berry with a hard rind and no internal divisions, botanically called a pepo. The sweet, juicy flesh is usually deep red to pink, with many seeds that are black when mature, white when immature. Seedless varieties also exist. The fruit can be eaten raw or pickled, and the rind is edible after cooking. It may also be consumed as a juice or an ingredient in mixed beverages. Watermelon originated in Africa, where it was first cultivated. Kordofan melons from Sudan are the closest relatives and may be progenitors of modern, cultivated watermelons. Wild watermelon seeds were found in Uan Muhuggiag, a prehistoric site in Libya......read more on Wikipedia.
