[Subshrub] shrub, tree, trunk bark smooth or scaly; glands 0 or embedded in epidermis. Leaf: opposite or alternate, persistent, generally glandular when young. Inflorescence: generally axillary, raceme, panicle, cyme, or flowers 1. Flower: generally bisexual, parts in 4s, 5s, generally ± white; hypanthium exceeding ovary or not; stamens generally many; ovary [rarely superior to] inferior, 2–5(18)-chambered; placentas axillary, just below top, or basal, ovules few to many, generally in 2–many series. Fruit: berry, capsule, nut. Seed: 1–many; coat membranous to ± leathery or hard, bony; embryo starchy or oily (of great taxonomic importance).
100 genera, ± 3500 species: many species tropical America, Australasia, fewer Africa, southern Asia; economically important for timber (Eucalyptus), spices (Syzygium aromaticum (L.) Merr. & L.M. Perry, cloves; Pimenta dioica (L.) Merr., allspice), edible fruits (Psidium guajava L., guava; Acca sellowiana (O. Berg) Burret, pineapple guava), many orns (Eucalyptus, Melaleuca, several other genera). [McVaugh 1968 Taxon 17:354–418] Apparently of Gondwanan origins; tropics, subtropics, Mediterranean climates. Chamelaucium uncinatum Schauer, Luma apiculata (DC.) Burret, Melaleuca citrina (Curtis) Dum.Cours., Myrtus communis L., Syzygium australe (Link) B. Hyland are waifs. —Scientific Editor: Thomas J. Rosatti.

Key to Myrtaceae
Shrub, tree, generally glabrous. Leaf: opposite, persistent, papery or leathery. Inflorescence: cyme, panicle, or raceme, terminal, axillary, sometimes on older stems. Flower: calyx lobes, petals 4 [(5)]; hypanthium prolonged above ovary, base often long-acuminate; ovaries chambers generally 2, each few–many-ovuled. Fruit: berry. Seed: 1–2(5), seed coat membranous; embryos sometimes many, distorted; cotyledons separate, thick, planoconvex.
± 500 species: old world tropics. (Greek: joined, from paired structures of some species) [Hyland 1983 Austral J Bot Suppl Ser 9:1–164]
