- Leaves simple, alternate with distinct collecting vein.
- Copious white latex (rarely tan or clear yellow).
- Free or fused deciduous stipules.
- Non-showy, wind-pollinated flowers without petals.
- Fruit mostly one-seeded drupes, rarely multi-seeded fleshy aggregates.
Diagnosis: Trees and herbs, copious white or tan latex, with free or fused stipules, leaves simple, alternate, usually with pinnate venation, the basal lateral veins short, well-developed marginal vein. 1. Leaves distichous, serrate or less often entire (most genera). 2. Leaves spiraled, always entire, fleshy (Ficus).
|Bombacaceae||(Quararibea): no latex, petiole swollen apically.
|Euphorbiaceae||: nectar glands on petiole or base of blade, leaves often spiraled.
|Flacourtiaceae||: no latex, marginal vein poorly developed.
Diversity: Total: 12 genera, 45 species. Trees: 10 genera, 43 species (including some mostly hemi-epiphytic Ficus species).
