Morphology General Habit
Mostly glabrous trees, shrubs or geoxylic subshrubs
Morphology Leaves
Leaves opposite, penninerved, usually with an intramarginal vein
Morphology Reproductive morphology Inflorescences
Inflorescences usually terminal and axillary
Morphology Reproductive morphology Flowers
Flowers solitary and axillary or more usually in cymes or panicles, 4–5-merous; receptacle sometimes prolonged above the ovary and base usually narrowed to form a pseudopedicel above the bracteoles which are usually inconspicuous and deciduous
Morphology Reproductive morphology Flowers Calyx
Calyx-lobes persistent or falling
Morphology Reproductive morphology Flowers Corolla
Petals free or more or less united into a calyptra (in African species)
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens usually numerous and conspicuous, in several series borne on receptacle rim, free or inconspicuously arranged in 4 obscure bundles; filaments filiform; anthers dehiscing by longitudinal lateral slits
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 2(rarely 3–4)-locular, the locules usually near distal part of ovary; ovules few to numerous in each locule, in crowded subcapitate clusters attached to the central partitions
Morphology Reproductive morphology Flowers Gynoecium Pistil
Style filiform; stigma minute
Morphology Reproductive morphology Fruits
Fruit a fleshy or dry leathery berry with 1–2 (rarely more) ± large seeds; testa membranous to crustaceous; cotyledons fleshy, usually completely free or partially fused (rarely completely fused).

Morphology General Habit
Trees, shrubs or rhizomatous, geoxylic suffrutices.
Morphology Reproductive morphology Inflorescences
Inflorescence usually a terminal, many-flowered, often compound and corymbose cyme, more rarely (S. cumini) a lateral cyme from the axils of fallen leaves.
Morphology Reproductive morphology Inflorescences Bracteoles
Bracteoles very small and inconspicuous, fugacious.
Morphology Reproductive morphology Flowers
Flowers bisexual, pyriform in bud.
Morphology Reproductive morphology Flowers Receptacle
Receptacle gradually narrowed towards base to form a stout "pseudopedicel" above the articulation and expanded distally to form a rim-like "upper receptacle" beyond the apex of the ovary, which bears the stamens on its margin.
Morphology Reproductive morphology Flowers Calyx
Calyx forming an indistinct, irregularly lobed extension to the upper receptacle (African species) or distinctly lobed (S. jambos), eciliolate.
Morphology Reproductive morphology Flowers Corolla
Petals 4, suborbicular or obovate, caducous, cohering and falling together as a calyptra (African species) or falling separately (S. jambos), eciliolate.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens numerous, free, more than twice as long as the petals, very conspicuous, white or cream or bright red (not in F.Z. area).
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 2-locular; placentation axile; ovules numerous.
Morphology Reproductive morphology Flowers Gynoecium Style
Style slightly longer than the filaments, punctiform.
Morphology Reproductive morphology Fruits
Fruit a berry, usually 1-seeded.
Morphology Reproductive morphology Seeds
Cotyledons large, completely free.
