Bignay is a small, smooth, dioecious tree, 4 to 10 meters high. Leaves are shiny, oblong, 8 to 20 centimeters long, pointed at the tip, rounded or pointed at the base. Spikes are axillary or terminal, simple, and usually 5 to 15 centimeters long. Flowers are small and green. Male flowers are about 1.5 millimeters in diameter, borne on spikes, while the female flowers grow out on racemes. Fruit is fleshy, red, acid, edible, ovoid, and about 8 millimeters long, single-seeded, and borne in grapelike pendant clusters (often paired), wrinkled when dry, the seed becoming somewhat compressed.
