- Thin orange layer in bark.
- Tiny free stipules.
- Leaves alternate, distichous, and crenate.

Diagnosis: Trees and lianas, thin orange layer in bark, free stipules, twigs often ridged, leaves simple, margin crenate (sometimes obscurely); forming two groups- one simple, alternate, mostly distichous, the other simple, opposite (including Hippocrateaceae).
Local distribution: Widespread.
|Flacourtiaceae||: tertiary veins at mid leaf perpendicular to midvein, some with nectar glands or pellucid dots, larger stipules.
|Euphorbiaceae||: latex or clear exudate fro petiole, some with nectar glands.
|Myrtaceae||: leaves entire, pellucid dots present.
|Rhamnaceae||: serrate with straight lateral veins.
|Rhizophoraceae||: sparse inconspicuous teeth, curved petioles.
Diversity: Total: 8 genera, 13 species. Trees: 7 genera, 10 species.
Comments: The orange bark layer is usually diagnostic for the family.
