    Myrtaceae, F. White. Flora Zambesiaca 4. 1978

    Evergreen trees and shrubs.
    Juvenile leaves mostly horizontal, opposite, cordate and sessile. Adult leaves sclerophyllous, mostly vertical, 2-facial, alternate, petiolate, usually elongate and narrowly lanceolate.
    Inflorescence fundamentally a dichasial cyme showing various degrees of expansion, aggregation or compaction. The unit inflorescence or “umbel” is in fact a condensed and usually partly reduced dichasium.
    Receptacle-tube obconical, campanulate or oblong, adnate to the ovary, truncate and entire after the operculum has fallen or with 4 minute teeth.
    Perianth variously modified (see below) to form an operculum which falls off entire when the filaments expand.
    Stamens numerous in several series, free or very rarely very shortly fused at the base into 4 clusters.
    Ovary inferior, 3–6-locular; placentation axile; ovules numerous in each locule; style subulate, rarely clavate, with a small truncate, capitate or rarely peltate stigma.
    Fruit usually hard and woody, consisting of the more-or-less enlarged truncate receptacle-tube enclosing the capsule, which is always adnate to the receptacle-tube although often readily separable from it, opening by as many valves as there are locules.

    Flower usually in umbel-like condensed usually pedunculate dichasial cymes, either single or more rarely paired in the leaf-axils or in terminal corymbose panicles; flowers 3 or more per umbel or in a few species solitary, sessile or pedicellate
    Calyx-limb and corolla each or together forming an operculum which is shed at anthesis but calyx-lobes sometimes free, falling separately or together
    Stamens numerous; anthers dehiscing by pores or slits; connective mostly with a dorsal or terminal gland
    Ovary 2–7-locular, inferior or partly superior; ovules numerous
    Capsule usually woody, loculicidal or rarely circumscissile with scars left by falling operculum and androecium; disc convex or descending; valves included to exserted.
