Guamuchil, or Manila tamarind, is native to Mexico, Central America, Colombia, and Venezuela. It reaches a height of 60 feet, with a trunk 2 feet in diameter that frequently branches close to the ground and grows crooked. The bark of young trees has characteristic bulges. The leaves  have two pairs of leaflets, each up to 2 inches long, one the mirror image of the other. Inflorescences are about half an inch in diameter. Fruits are spirally-twisted pods, up to 5 inches long, that open on both sides to expose several black seeds surrounded by white pulp. It flowers from autumn to spring, and fruits ripen from winter to summer. The wood is used to make charcoal. The generic name means ape earring, in reference to the shape of the fruit. The species name refers to the taste of the fruit, although it is not really sweet.

The photographed tree is in the northeastern section of the old athletic field. There are other trees near the tennis courts of this same field and southwest of Building B.
