The tree and fruit are closely related to litchi. The tree is a tropical and sub-tropical evergreen, up to 40 feet, with pinnate leaves. The fruits are borne in panicles or loose clusters. They are globular, about an inch in diameter, with a nearly smooth rind and a single, rather large seed. The pulp, between the rind and the seed, is gelatinous and of pleasant flavor. The rind separates from the pulp readily. Only the pulp is consumed. The fruit ripens a little later than litchi, and the tree is a little more cold resistant.
