Morphology General Habit
Perennial herbs, sometimes shrubs, sometimes epiphytic, stems often rather juicy or succulent, monoecious or dioecious by abortion
Morphology Leaves
Leaves basically opposite, but one leaf of each pair is either reduced or early falling, thus the plants appear to have alternate leaves; lamina very unequal-sided at base, entire, crenate or serrate, rather fleshy; stipules intrapetiolar, fused to the apex
Morphology Reproductive morphology Inflorescences
Male inflorescences small pedunculate clusters; ♀ inflorescences capitate, with a fleshy subglobose receptacle on short fleshy peduncles, in the axils of fallen leaves
Morphology Reproductive morphology Flowers
Male flowers 4–5-merous; rudimentary ovary present, obovoid Female flowers 4–5-merous, with very short perianth; ovary straight, exceeding the perianth; stigma sessile, penicillate
sex Male
Male flowers 4–5-merous; rudimentary ovary present, obovoid
sex Female
Female flowers 4–5-merous, with very short perianth; ovary straight, exceeding the perianth; stigma sessile, penicillate
Morphology Reproductive morphology Fruits

Morphology Reproductive morphology Flowers
Female flowers sessile with a persisting perianth of 4–5 free tepals; ovary erect, symmetrical, with a penicillate stigma. Male flowers pedicellate, pentamerous (rarely tetramerous), with a rudimentary pistillode.
