How do watermelons differ from melons?

Both watermelon and melon are in the cucurbit family, the Cucurbitaceae. However, they are in different genera. Watermelon is Citrullus lanatus, and melon is Cucumis melo. Actually, cucumber (Cucumis sativus) and melon are more closely related than watermelon and melon. Melon is also known as muskmelon, but that term has been also used to describe a type of melon with netted rind. Munger and Robinson define melon in their article: Munger, H.M. and R.W. Robinson. 1991. Nomenclature of Cucumis melo L. Cucurbit Genetics Cooperative Report 14:43-44.

Robinson and Decker-Walters describe watermelon and melon in their book: Robinson, R.W. and D.S. Decker-Walters. 1997. Cucurbits. Science Publishers, Enfield, NH.
