    Myrtaceae, B. Verdcourt, B.Sc., Ph.D.. Flora of Tropical East Africa. 2001

    Mostly glabrous trees, shrubs or geoxylic subshrubs
    Leaves opposite, penninerved, usually with an intramarginal vein
    Inflorescences usually terminal and axillary
    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
    Calyx-lobes persistent or falling
    Petals free or more or less united into a calyptra (in African species)
    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
    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
    Style filiform; stigma minute
    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).

    Myrtaceae, F. White. Flora Zambesiaca 4. 1978

    Trees, shrubs or rhizomatous, geoxylic suffrutices.
    Inflorescence usually a terminal, many-flowered, often compound and corymbose cyme, more rarely (S. cumini) a lateral cyme from the axils of fallen leaves.
    Bracteoles very small and inconspicuous, fugacious.
    Flowers bisexual, pyriform in bud.
    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.
    Calyx forming an indistinct, irregularly lobed extension to the upper receptacle (African species) or distinctly lobed (S. jambos), eciliolate.
    Petals 4, suborbicular or obovate, caducous, cohering and falling together as a calyptra (African species) or falling separately (S. jambos), eciliolate.
    Stamens numerous, free, more than twice as long as the petals, very conspicuous, white or cream or bright red (not in F.Z. area).
    Ovary 2-locular; placentation axile; ovules numerous.
    Style slightly longer than the filaments, punctiform.
    Fruit a berry, usually 1-seeded.
    Cotyledons large, completely free.
