Leaves alternate, crenato-serrate or entire, pinnately veined, sometimes also 3 - 5-pliveined at base; secondary veins upcurved, diminishing near margin, joining superadjacent veins by a series of cross-veins and giving rise to lateral branches, each to end in a gland beneath the teeth or at margins; stipules absent. Flowers unisexual (plants dioecious), rarely bisexual in axillary or terminal short bracteate racemes or racemose fascicles; pedicels articulated. sepals 4 - 5, imbricate, subpersistent. Petal absent. Disc extrastaminal, usually consisting of distinct glands inserted before sepals, and annular or lobed in female. Male flowers: Stamens numerous; anthers oblong or globular, usually dorsifixed and versatile; pollen tricolporate, reticulate, subprolate. Pistillode absent. Female flowers: Carpels (2-) 3 - 6 (-10), connate into as many incompletely loculed ovary with deeply intruding placentae; ovules usualy 2 in each locule inserted on dividing walls. Styles free or connate, rarely absent; stigma retuse or shortly bilobed. Fruit fleshy, an indehiscent berry with indurate endocarp, globose when fresh, characteristically becoming obtusely cubiform-angular and constricted in middle when dry with 2 superposed pyrenes in each locule.
