    Dioecious or monoecious aromatic shrubs or small trees. Leaves opposite, generally elliptic to lanceolate, pinnately veined, margin serrate, the petioles connate into a pronounced petiolar sheath enclosing first the apical bud and later the stem, stipules setose to fimbriate. One or two superposed axillary buds may develop from each leaf axil, these buds sometimes becoming exserted from the petiolar sheath by elongation in the nodal region. When the inflorescence is monoecious the terminal bud and the first pair of subtending axillary branches often bear pistillate flowers, while the second and subsequent pairs bear staminate flowers. Staminate catkin of 1 to several cylindrical spikes which greatly elongate at anthesis; flowers naked, ebracteate, sessile or subsessile, each composed of a single bilocular stamen, the connective variously produced, the anthers longi- tudinally dehiscent. Pistillate inflorescence racemiform, paniculiform or spiciform; flowers monochlamydeous, bracteate, perianth fused into a tri-lobed urceolate cup persistent in fruit; ovary unilocular, uniovulate; style short, deciduous; fruit a small three-angled drupe.
