Small to large, densely foliaged trees; young twigs glabrous or nearly so. Leaves smaller than those of pomelo (var. maxima) with narrower obovate-oblanceolate petiolar wings. Petals shorter. Fruits smaller, globose to oblate, 8 - 12 cm across, yellowish; pulp-vesicles coherent, pinkish, not easily separable, juice abundant.

Distrib. Probably a native of Jamaica where it might have originated as a chance hybrid between the true pomelo and the sweet orange (Janaki Ammal in Curr. Sci. 22: 178 - 179.). Cultivated in N. India and other subtropical countries for its fruits, commonly called grape fruit.

Notes. The grape fruit tree shares many characters of both pomelo and sweet orange, often with more of that of the pomelo. In habit, leaves, flowers and internal characters of fruits, it resembles the pomelo while in the external fruit structure and nature of pulp-vesicles it resembles the sweet orange.
