Citrullus colocynthis, with many common names including Abu Jahl's melon, colocynth, bitter apple, bitter cucumber, egusi, vine of Sodom, or wild gourd, is a desert viny plant native to the Mediterranean Basin and West Asia, especially the Levant, Turkey, and Nubia.

Egusi (Yoruba) is the name for the protein-rich seeds of certain cucurbitaceous plants, which, after being dried and ground, are used as a major ingredient in West African cuisine.
