Abobra is a monotypic genus of flowering plants in the gourd family Cucurbitaceae (order Cucurbitales), containing just one species: Abobra tenuifolia (synonyms: Abobra viridiflora Naudin, Bryonia tenuifolia Hook. & Arn.). The genus is native to temperate South America, with its range spanning Argentina, Brazil, and Uruguay.
The plant is a dioecious, perennial climber, capable of reaching up to 4 m (13 ft) in height. Its flowers are pale green and emit a strong fragrance, blooming between July and August in the Southern Hemisphere spring. The fruit is small and ovoid, approximately 14 mm in diameter — giving rise to the common name "cranberry gourd" — and seeds ripen between September and October. The fruits are edible, and the species is occasionally cultivated both as an ornamental and for its fruit.
Being monotypic, Abobra has no close congeners; it sits within Cucurbitaceae alongside familiar genera such as Cucumis, Cucurbita, and Lagenaria.
