Coccoloba uvifera is a species of flowering plant in the buckwheat family, Polygonaceae, that is native to coastal beaches throughout tropical America and the Caribbean, including southern Florida, the Bahamas, Barbados and Bermuda. Common names include Seagrape and Baygrape.

It is a sprawling evergreen shrub or small tree that reaches a maximum height of 8 m (26 ft), but most specimens are little more than 2 m (6.6 ft) tall[citation needed]. It has large, round, leathery leaves (up to 25 cm/9.8 in in diameter) with a primary vein that has a red color extending from the base, and the entire leaf turns red as it ages. The bark is smooth and yellowish.

In late summer it bears green fruit, about 2 cm (0.79 in) diameter (Alden et al. 1998), in large grape-like clusters. The fruit gradually ripen to a purplish color. Each contains a large pit that constitutes most of the volume of the fruit.
