[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
Tree, shrub. Stem: generally erect; bark shedding, smooth, or persistent near base (occasionally) or throughout, rough; twigs generally round. Leaf: juvenile generally opposite, horizontal, sessile, ± cordate, entire, glaucous; adult generally alternate, vertical, petioled, ± lanceolate, entire, glandular, glabrous, generally same color on both sides. Inflorescence: axillary, (1)3–many-flowered, stalked umbel or panicle-like cluster of such umbels. Flower: perianth (generally, entirety of calyx lobes, petals) fused into bud cap in bud, bud cap shed at flower; stamens many, in several series, generally all fertile, white (yellow, red, pink); ovary chambers 3–6, fused to hypanthium. Fruit: capsule, thick-walled, woody, generally smooth, generally dehiscing at top. Seed: generally 1–3 mm, wind-dispersed.Key to Eucalyptus
± 700 species: most endemic to Australia; > 250 species. Cult in California; important for oils, tannins, timber, orns. (Greek: true cap, for bud cap) [Brooker 2000 Austral Syst Bot 13:79–148] World's largest flowering plants, some > 100 m; Eucalyptus pulverulenta Sims excluded, cultivated only.
Stem: 10–20 m, generally straight; bark shed in large irregular patches, ± smooth, white, often mottled gray, orange, or tan. Leaf: 8–15 cm, 2–3 cm wide, ± widely lanceolate, lighter abaxially. Inflorescence: umbel, 7–11-flowered, generally on leafless branches. Flower: hypanthium < 1 cm, cylindric or urn-shaped, ± ridged; bud cap hemispheric to conic, < hypanthium, > hypanthium in width; stamens white. Fruit: 1–1.5 cm, ± urn-shaped, ribbed; valves included.
Uncommon. Disturbed coastal areas; generally < 200 m. Central Coast, South Coast, Peninsular Ranges; native to southern Australia. TOXIC to livestock in Australia. Commonly cultivated in southern California. Apr–Jul [Online Interchange]
