Cucumis humifructus, the aardvark cucumber or aardvark pumpkin, is a kind of cucumber from southern Africa, tropical Africa, and Madagascar which fruits underground. It is reliant on the aardvark to eat the fruit in order to spread and re-bury the seeds of the plant. The species was described in 1927, with the name spelled C. humofructus, but this is corrected to C. humifructus following the International Code of Nomenclature for algae, fungi, and plants.
