Calaba, or santa-maria, is native to the Antilles. It reaches a height of 150 feet, with a trunk 7 feet in diameter. The leaves are up to 5 inches long, they have a prominent central vein and many fine parallel veins. Flowers are up to half an inch in diameter and appear in groups among the foliage. Fruits are up to 1 inch in diameter, they are smooth and green at first, turning rough and reddish-brown before falling. It flowers during spring and summer, and fruits fall during autumn and winter. Bats eat the pulp of the green fruit and disperse the seeds. The generic name means beautiful leaf. The species name refers to its geographic origin.

The photographed tree is across the entrance to the Buildings and Grounds Department. From the Coliseum to the Alumni swimming pool there are two rows of calaba intermixed with kamani trees. There are other trees southeast of the Entomology Laboratory, in the grounds of the greenhouse behind the Celis Building, north of the Chemical Engineering Building, and at the Research and Development Center.
