Common Names:  Sea Grape

Family:  Polygonaceae

Habit Coccoloba uvifera grows as a low small shrub to large trees over 17 meters in height.  The leaves are arranged alternately, to 25 cm in length, ovate to cordate to orbicular with a rounded leaf apex and entire margin.  There is an ocrea extending from the petiole surrounding the stem above the node.

The dioecious actinomorphic flowers are arranged in racemes. The inflorescence is longer than the length of the leaves. The calyx has 5 green sepals. The corolla has 5 whitish petals.  There are 8 stamens.  In staminate flowers the stamens are fertile and are 3 times the size of the infertile ovary.  In carpellate flowers the stamens are infertile and shorter than the ovary.  In both types of flowers the calyx, corolla, and stamens are fused to form a shallow hypanthium.  At the base of the hypanthium are nectaries.  The ovary is superior with a single locule.  The fruit is a drupe that turns reddish-purple at maturity and occurs in large long clusters.
