Morphology General Habit
Shrubs to medium-sized trees without buttresses
Morphology Leaves
Leaves mostly rounded or retuse at apex, only rarely acuminate, with, ± rounded extra-floral nectary at base of midrib above and sometimes additional ones in lower nerve-axils; midrib and lateral nerves ± impressed above, prominent beneath, the venation almost always very densely reticulate beneath; indumentum very varied; hairs simple, fasciculate or stellate, short or rather long, straight, curved or coiled, with small spherical glands sparse to dense on both surfaces, often making the blades viscid
Morphology Reproductive morphology Flowers

Morphology Reproductive morphology Flowers Perianth
Sepals and petals densely silky-pilose or velvety outside, pilose at base inside
Morphology Reproductive morphology Flowers Receptacle
Receptacle slightly produced into a very short broad androgynophore
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens numerous with short anthers, the connectives often produced into short triangular or ovate appendages at the apex
Morphology Reproductive morphology Flowers Gynoecium Ovary

Dipterocarpaceae, P. Duvigneaud. Flora Zambesiaca 1:2. 1961

Morphology General Habit
Shurbs to medium-sized trees, without buttresses.
Morphology Leaves
Leaves very rarely acuminate, with a more or less rounded extra-floral nectary on the upper surface at the base of the midrib, and sometimes at the base of the lower lateral nerves; midrib and lateral nerves depressed above and prominent beneath; reticulation very dense, isodiametrical, scarcely to strongly prominent beneath, in the latter case turning the interreticular areoles into deep cavities; indumentum extremely variable; hairs simple, penicillate, or stellate, straight, curved, curled, or coiled, from very short to long, with punctiform spherical glands, sometimes making the lamina viscid, abundant or dispersed on the two surfaces of the leaf.
Morphology Reproductive morphology Flowers
Flowers small, in axillary clusters, with very hairy sepals and petals; receptacle produced into a very short broad androgynophore.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens numerous; anthers sohrt, very often produced at the apex into a triangular or ovate appendage.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary hairy, completely 3-locular with 2 ovules in each loculus.
Morphology Reproductive morphology Fruits
Fruit subglobose, with a hard thick pericarp and with 1 cavity containing 1 seed, surrounded by the 5 subequal wings of the accrescent calyx; wings with minute penicillate hairs outside and inside.
