Tree, shrub, evergreen
Leaves simple, opposite or alternate, entire, often gland-dotted
Inflorescence: umbel, panicle of umbels, or flowers 1–3 in axils
Flower generally bisexual, radial; hypanthium cylindric, deltate, ± cup-shaped, or urn-shaped; sepals, petals generally 4–5, free or sometimes fused together to form a deciduous bud cap; stamens generally many, ± showy, borne near top of hypanthium, free or in 4–5 clusters; ovary generally inferior, chambers 1–many, style 1
Fruit: generally berry or capsule
Seeds generally many, small
Genera in family: ± 100 genera, 3000 species: tropical, subtropical, especially s hemisphere; economically important for timber (Eucalyptus ), spices (Syzygium aromaticum , cloves; Pimenta dioica , allspice), edible fruits (Psidium guajava , guava; Feijoa sellowiana , pineapple guava), many ornamental
