In its native distribution it reaches a height of 60 feet, with a trunk 4 or more feet in diameter. The leaves measure up to 18 inches long. Flowers are up to 3 inches in diameter and form a carpet around the trunk when they fall. Fruits are up to 3 inches long, the pulp is white and tastes like apples. It flowers and produces fruit from spring to autumn. The generic name means coupled, in reference to the paired arrangement of the leaves along the branches. The species name indicates that it is native to Malacca, one of the states of Malaysia.
