Crossopetalum rhacoma

Common Names: Maidenberry, Rhacoma, Christmas Berry, Snake Berry
Scientific Name: Crossopetalum rhacoma
Family: Celastraceae
Native Range: South Florida and the Florida Keys through the Caribbean, southern Mexico, Central America, and into northern South America.

Crossopetalum rhacoma is a native Caribbean shrub or small tree that can be easy to overlook until it is flowering or fruiting.

It belongs to the staff-vine family, Celastraceae, and usually grows as a dense shrub or small tree. In some habitats it may remain fairly compact, while in more favorable conditions it can become several metres tall.

The leaves are small, evergreen, and typically arranged opposite one another on the stems. Their leathery texture helps the plant tolerate exposed tropical conditions.

The flowers are tiny, but worth looking at closely.

They usually appear in small clusters from the leaf axils and may be pale green, whitish, reddish, or purplish. Members of the genus typically have four petals and four sepals, and the flowers contain a fleshy nectar-producing disk.

Because the flowers are small, visitors often notice the fruit first.

The fruits are small drupes that ripen to a bright red. Each fruit usually contains one or two seeds. The vivid red fruits stand out strongly against the green foliage and are likely responsible for common names such as “Christmas Berry.”

In suitable tropical conditions, Crossopetalum rhacoma may flower and fruit over a long season, and sometimes both flowers and ripe fruit can be present on the same plant. That makes it particularly useful for phenology observation.

The species occurs naturally in a wide range of Caribbean and subtropical habitats. In the Bahamas and nearby islands, it is found in dry broadleaf evergreen forest, woodland, shrubland, and pine woodland. In Florida it is also associated with coastal hammocks and sandy habitats.

One interesting thing about this plant is that it does not depend on showy flowers to attract attention.

Its strategy is much quieter:

small evergreen leaves, tiny flowers, and bright red fruit.

And that makes it a good example of something visitors often discover in a botanical garden:

Some of the most interesting plants are not necessarily the biggest or most dramatic. Sometimes you have to stop and look closely before the details reveal themselves.
