<pre>

    The watermelon is a member of the cucumber family known as the Cucurbitaceae, which includes gourds as well. 
    They're grown like vegetable crop using vegetable production systems. ... So even if the watermelon is mostly eaten as a fruit, 
    it got lumped in with vegetables in some circles of thought.
