Watermelon (Citrullus lanatus (Thunb.), family Cucurbitaceae) can be both the fruit and the plant a vine-like (scrambler and trailer) plant originally from southern Africa, and is one the most common types melon. This flowering plant produces a special type fruit known by botanists as a pepo, a berry which has a thick rind (exocarp) and fleshy center (mesocarp and endocarp); pepos are derived from an inferior ovary, and are characteristic the Cucurbitaceae. The watermelon fruit, loosely considered a type melon (although not in the genus Cucumis), has a smooth exterior rind (green, yellow and sometimes white) and a juicy, sweet interior flesh (usually pink, but sometimes orange, yellow, red and sometimes green if not ripe).
History
Watermelon is thought to have originated in southern Africa, where it is found growing wild, because it reaches maximum genetic diversity there, resulting in sweet, bland and bitter forms. Alphonse de Candolle, in 1882, already considered the evidence sufficient to prove that watermelon was indigenous to tropical Africa. Though Citrullus colocynthis is ten considered to be a wild ancestor watermelon and is now found native in north and west Africa, Fenny Dane and Jiarong Liu suggest on the basis chloroplast DNA investigations that the cultivated and wild watermelon appear to have diverged independently from a common ancestor, possibly C. ecirrhosus from Namibia.
