Petals 4 or 5, greenish-white to yellow, imbricate, equilateral, deciduous in female flowers. Stamens in 4 or 5 antepetalous fascicles or apparently not fascicled, many, filaments slender to stout, free or ± united or fascicles ± united to form a lobed or conical synandrium; anthers dorsifixed or ± immersed in a synandrium, dehiscing variously, without gland on connective; staminodes various or absent; sterile fascicles present and free or united, or absent. Ovary 2-5(-12)-locular, placentae axile, each placenta 1-ovulate, in male flowers rudimentary or absent; styles absent or very short; stigmas 2-5(-12)-lobed, peltate, or forming a uniform mass.
