IncludingAntidesmeae (Antidesmataceae) Sweet ex Endl.

Habit and leaf form. Small trees, or shrubs.Leaves alternate; distichous; leathery; shortly petiolate; simple. Lamina entire; ‘with conspicuous looping venation’. Leaves conspicuously stipulate. Stipules caducous. Domatia occurring in the family; manifested as pockets.

Leaf anatomy. Minor leaf veins without phloem transfer cells.

Stem anatomy. Secondary thickening developing from a conventional cambial ring.

Reproductive type, pollination. Fertile flowersfunctionally male, or functionally female. Plants dioecious. Female flowers without staminodes. Gynoecium of male flowers pistillodial to vestigial (small, cylindrical), or absent.

Inflorescence, floral, fruit and seed morphology. Flowers aggregated in ‘inflorescences’; in racemes, or in spikes, or in panicles. The ultimate inflorescence unit cymose, or racemose. Inflorescences terminal, or axillary. Flowers very small. Hypogynous disk present; extrastaminal (in male flowers, or surrounding each stamen); of separate members, or annular (variously formed, the lobes free or united).

Perianthsepaline; 3–5(–8). Calyx 3–5(–8); gamosepalous; imbricate, or open in bud.

Androecium (2–)3–5(–6). Androecial members free of the perianth; free of one another. Androecium in male flowers, exclusively of fertile stamens. Stamens (2–)3–5(–6); isomerous with the perianth; oppositisepalous; inflexed in bud (the filaments inflexed); filantherous (the filaments long and filiform). Anthersdehiscing transversely (or transversly and apically); bilocular (the thecae divergent, almost free, borne on a short thick connective). Pollen grains aperturate; 3 aperturate; colporate.

Gynoeciumostensibly 1 carpelled. Carpels reduced in number relative to the perianth. The pistil 1 celled. Gynoecium syncarpous (pseudomonomerous); synstylovarious; superior. Ovary 1 locular. Gynoecium stylate. Styles 1; apical to lateral (subterminal); shorter than the ovary (short). Stigmas 2–4 (short, spreading). Placentation apical. Ovules in the single cavity 2; pendulous.

Fruit fleshy; indehiscent; a drupe (small, ovoid or flattened, often oblique and with a lateral, persistent style). The drupes with one stone (with conspicuous foveolate-reticulate endocarp). Fruit 1–2 seeded. Seeds endospermic (the endosperm fleshy). Embryo well differentiated. Cotyledons 2. Embryo chlorophyllous; straight.

Geography, cytology. Paleotropical. Sub-tropical to tropical. Palaeotropical and subtropical, Africa and Asia.

Taxonomy.Subclass Dicotyledonae; Crassinucelli. Dahlgren’s Superorder Malviflorae; Euphorbiales (?). Cronquist’s Subclass Rosidae; Euphorbiales. APG 3 core angiosperms; core eudicot; Superorder Rosanae; fabid; Order Malpighiales (as a synonym of Euphorbiaceae).
