This native Caribbean tree is Black Mampoo, Guapira fragrans. It is also sometimes called Wild Mampoo. Its natural range extends throughout the Caribbean and into northern South America, and it is one of the more common native trees in the forests of the Virgin Islands.

Black Mampoo usually grows as a small to medium-sized tree, although older specimens can become quite substantial. Its crown is often broad and irregular, providing shade and shelter for birds and other wildlife.

The leaves are simple, smooth-edged and arranged opposite one another along the stems. They are usually oval or somewhat elongated, with a glossy green upper surface. The new growth may be lighter in color before darkening as the leaves mature.

The flowers are small and not especially showy, but they often appear in clusters and may have a noticeable fragrance. That scent is reflected in the scientific name fragrans, meaning fragrant.

Black Mampoo produces separate male and female flowers, often on different trees. This means that a female tree usually needs a nearby male tree for pollination and fruit production.

After flowering, the female tree develops small, fleshy fruits. They begin green and gradually become red, purple or nearly black as they ripen. The fruits are an important food source for birds, which help spread the seeds through the surrounding forest.

The bark is generally gray to dark brown and may become rougher with age. The common name “Black Mampoo” may refer to the darker appearance of the trunk and branches, helping distinguish it from other trees locally called mampoo.

Although it does not have the enormous flowers or unusual form of some tropical ornamentals, Black Mampoo is ecologically important. It is a genuine part of the native Caribbean forest, providing fruit, cover and nesting habitat for wildlife.

This is a good tree to point out because it reminds us that a botanical garden is not only about spectacular imported plants. Some of its most valuable trees are the quiet native species that have supported Caribbean wildlife for generations.
