African Cucumber

The horned melon is a strange-looking fruit that is native to Southern Africa, and has only recently (in the past century) been introduced to other parts of the world, namely Australia and New Zealand, which is where it picked up the name kiwano, due to its similar consistency and appearance to kiwis. However, this fruit is not biologically linked to kiwis, and is actually closer in nutritive and evolutionary terms to cucumbers and zucchinis. (mmn.com)
