Cucumis anguria, commonly known as bur cucumber, bur gherkin, cackrey, gooseberry gourd, maroon cucumber, West Indian gherkin, and West Indian gourd, is a vine that is indigenous to Africa, but has become naturalized in the New World, and is cultivated in many places. It is similar and related to the common cucumber (C. sativus) and its cultivars are known as gherkins.
Cucumis anguria is a thinly stemmed, herbaceous vine scrambling up to 3 meters long. Fruits (4–5 cm × 3–4 cm) are longly stalked, and ovoid to oblong. The surface of the fruits have long hairs covering a surface having warts and/or spines; the inner flesh is palid to green.
Cucumis anguria is primarily grown (as a crop plant) for its edible fruit, which are used in pickling, as cooked vegetables, or eaten raw. The flavor is similar to that of the common cucumber. C. anguria fruits are popular in the northeast and north of Brazil, where they are an ingredient in the local version of cozido (meat-and-vegetable stew).
