Marah (plant) in the context of Marah oreganus

The cucumber (Cucumis sativus) is a widely-cultivated creeping vine plant in the family Cucurbitaceae that bears cylindrical to spherical fruits, which are used as culinary vegetables. Considered an annual plant, there are three main types of cucumber—slicing, pickling, and seedless—within which several cultivars have been created. The cucumber originates in Asia extending from India, Nepal, Bangladesh, China (Yunnan, Guizhou, Guangxi), and Northern Thailand, but now grows on most continents, and many different types of cucumber are grown commercially and traded on the global market. In North America, the term wild cucumber refers to plants in the genera Echinocystis and Marah, though the two are not closely related.

Wild cucumber may refer to:

• Armenian cucumber, a melon which when pickled is sold as "pickled wild cucumber" in Middle Eastern markets
• Cucumis sativus var. hardwickii, the wild ancestors of modern domesticated cucumbers (Cucumis sativus)
• Echinocystis, a genus of gourds found throughout most of North America
• Marah, a genus of gourds native to western North America
• Tsupu, a Coast Miwok elder also known as Wild Cucumber
