Juglans jamaicensis a newly grown shoot. The fruit is a drupe roughly 2 to 3 centimeters long with a black husk and a seed, which is an edible walnut meat, inside. In Puerto Rico there are only ten to fourteen trees of this species remaining. It is also rare in Cuba and Hispaniola. It is threatened by habitat loss. It may never have been common, but specimens were likely lost when forest was cleared for coffee plantations on Puerto Rico, and it was probably harvested for wood. The attractive wood is similar to that of the black walnut ("Juglans nigra"). This tree
Fruit tree forms whilst keeping the tree short and accessible for harvesting. Other shapes such as cordons, espaliers and fans offer opportunities for growing trees two dimensionally against walls or fences, or they can be trained to function as barriers. Some of the following fruit tree forms require training by tying the branches to the required form. Most require pruning to retain the desired structure. However, not all types of fruit tree are suitable for all forms; apples and pears do well as cordons and espaliers, for example, whereas cherries are more suited to the fan form.
