Male flowers usually smaller than the females, with a minute ostiole surrounded by 2-4 decussate pairs of tepals; androecium usually with 4 large outer stamens and up to 4 inner smaller stamens or staminodes which may be rudimentary and ± connate, occasionally 5 stamens in the outer whorl or as few as 2 stamens present; anthers opening by a single slit, with a filament or subsessile. Female flowers with the ostiole surrounded by about 5 decussate pairs of tepals; the inner pairs thickened and glandular; the upper half of the receptacle abscissing as a calyptra after anthesis; carpels numerous, stigma obtuse sessile on the apex of the ovary. Drupes sessile or stipitate.
