African cucumber
Native to Kalahari Desert, Africa

The African cucumber, horned melon or melano is a fruit that can be best
described as melon with horns. It originated in the Kalahari Desert and is now
present in California and New Zealand. The dark green pulp reminds one of
bananas, limes, passion fruit and cucumber. It is often used for decorating food
but also in smoothies and sundaes.
