Description: Climbers, herbs, subshrubs, shrubs or sometimes small trees, with stems often jointed and enlarged/swollen at the nodes; often succulent (Peperomia); many epiphytic or growing on rocks (Peperomia), often aromatic.
Leaves usually alternate, rarely opposite or whorled, simple, often oil gland-dotted, mostly entire, pinnately or palmately veined, sometimes succulent; [petiole frequently winged and sheathing the stem]; stipules present (often shed early) and adnate to petiole or absent.
Inflorescence axillary, leaf-opposed or terminal, erect to pendulous, usually condensed, raceme or spike, occasionally sparsely branched. Flowers minute, usually sessile or sometimes pedicellate, subtended by a minute, fleshy, often peltate bract, bisexual or unisexual and then plants monoecious. Perianth absent. Stamens 1–10, often with opposite, discrete loculi; anthers 2-locular, free or (in Peperomia) confluent, dehiscing longitudinally. Ovary superior, of 1–4 (–5) fused carpels, usually 1-locular with a basal or subbasal ovule; stigmas 1–several; style short or absent; ovary surrounded by 3 scale-like bracts.
Fruit a berry-like drupe, often sunken into the axis or fused to the bracts; seed 1.
