This is a small Malayan tree which is rare in Hawaii. It has regular, opposite, large, broad leaves; with the stems and branches four-sided. The purplish-white flowers are produced in clusters. The waxy light-green fruits, with a persistent calyx, resemble a small guava. These fruits have a very tough, pithy skin and pulp combined, which is edible, but too dry to be agreeable. The seed is large in proportion to the size of the fruit.
