Wampi is a small tree about 7 meters high. Leaves are dark green, pinnate, with 5 to 9 leaflets. Each leaflet has a stalk about 3 millimeters long, the blade ovate-elliptic, lanceolate or ovate, about 7 to 10 centimeters or more in length, pointed at the tip, much wider on one side of the base. Flowers are borne in terminal panicles, white, about 14 millimeters in diameter. Petals are five, white, and boat-shaped. Calyx is small and five-parted. Stamens are 10, with conspicuous yellow anthers. Ovary is five-celled, borne on a short stalk, covered with hairy nobs, and surrounded by a short style terminating in a rounded stigma. Fruit is ivory yellow, rounded, about 2 centimeters in diameter, very slightly flattened at the base, somewhat rounded at the tip, and borne in bunches. Skin of the fruit is thin and soft, dotted with minute, raised, somewhat darker-colored spots, covered with short hairs, and marked by five, usually very inconspicuous, longitudinal lines which are lighter in color than the remainder of the fruit. Flesh is yellowish white, soft, juicy, somewhat acid in taste; cross-section shows a division into five segments by thin, white lines. Usually one to four of the segments contain a single, rather large, flattened green seed, attached near the apex of the fruit.
