Morphology General Habit
Trees or shrubs
Morphology Leaves
Leaves simple, opposite or ternate, at first sight apparently without stipules but vestiges are present
Morphology Reproductive morphology Flowers
Flowers hermaphrodite, regular, in terminal or axillary cymes
Morphology Reproductive morphology Flowers Calyx
Calyx-tube joined to the ovary and produced above it as a cylindrical tube the margin of which is sinuate or minutely 4–5-toothed and ultimately deciduous
Morphology Reproductive morphology Flowers Corolla
Petals 4–5, imbricate, oblong-linear to spathulate, inserted on the margin of the calyx-tube, pubescent at the base, alternating with 4–5 small valvate more or less incurved pubescent coloured scales which close the throat in the young flower
Morphology Reproductive morphology Flowers Androecium
Stamens 4–5, inserted on the calyx-tube, alternating with the petals, inserted below the scales and at first hidden by them; filaments very short; connective thickened; anthers 2-celled, dehiscing inwardly; alternating with the stamens are 4–5 2-lobed hairy swellings at the base of the petals and usually interpreted as staminodes
Morphology Reproductive morphology Flowers Gynoecium
Ovary inferior, 3–5-locular with (1)2–3 pendulous ovules in each locule; placentation axile; style simple with a clavate stigma
Morphology Reproductive morphology Fruits
Fruit a 3–5-celled false drupe with 1 seed per cell
Morphology Reproductive morphology Seeds
Seeds with spiral or convolute embryos; endosperm absent

Morphology Reproductive morphology Inflorescences
Inflorescence paniculate, terminal or axillary, longer or equalling the leaves
Morphology Reproductive morphology Inflorescences Bracts
Bracts opposite, sometimes as long as the flower, papery or leathery, caducous or persistent at or after anthesis
