This tropical evergreen shrub or small tree has a slender main stem and can grow up to 7.5 m tall. The drooping branches are arranged in whorls around the main stem. It has a distinctive leaf arrangement, in which two kinds of leaves are arranged in four rows in almost the same plane of a branch. The rhombic and asymmetrical larger leaves (2-3 cm) spread in two rows on each side of the branch while the smaller leaves (0.5 cm) are lined in two rows on the upperside of the larger leaves. The undersides of the leaves can be hairy.

The yellowish- or pinkinsh-white, unisexual flowers grow in clusters in the axils of the large leaves. They give rise to ellipsoidal, red, fleshy drupes (2-2.5 cm).
