Black-olive, or ox-horn bucida, is native to the Antilles and Central America. It reaches a height of 100 feet, with a trunk 6 or more feet in diameter. It is extensively planted for ornament. The leaves are up to 3 inches long and are grouped at the end of branches. Flowers are grouped in spikes up to 4 inches long. Seeds develop inside the dry remnant of the flower, dispersing with the aid of wind and water. It flowers during winter and spring, and fruits mature during spring and summer. The generic name means ox. The species name means horn, together they refer to the abnormal development of fruits attacked by mites (last photograph).

The photographed tree is one of several specimens planted in the new athletic field. There are many other trees in the campus; for example, at the main entrance to the university, behind the General Library, behind the Art Musem and Academic Senate Building, in the Biology Building parking lot, and in the Angel Mangual Coliseum parking lot. The two trees behind the Museum were planted by Henry Cowles before 1940, while those in the coliseum parking lot were planted by Leonardo Flores during the 1980s.
