Characteristics

The actual fruit of this plant resembles the more modern, domesticated watermelons, except that it is smaller and more spheroid. The meat of the melon is more whitish and dense, though, and much stronger in flavor, akin more to the area on a domesticated watermelon where the red meat is just turning into the white rind. As noted above, while some people do eat it raw, it is more often cooked or prepared in some other way. Citron melon leaves are palmate in the early stages of growth, and deeply lobed in later
