Description

Family Myrtaceae

Trees or shrubs , evergreen , usually with essential oils-containing cavities in foliage , branchlets , and flowers. Stipules absent or small and caducous . Leaves opposite, occasionally alternate, occasionally ternate or pseudo-whorled; leaf blade with secondary veins pinnate or basal, often with intramarginal veins near margin , margin usually entire. Inflorescences axillary or terminal , cymose but variously arranged, 1- to many-flowered. Flowers bisexual , sometimes polygamous, actinomorphic . Hypanthium usually adnate to ovary and prolonged above it. Calyx lobes (3 or) 4 or 5 or more, distinct or connate into a calyptra. Petals 4 or 5, sometimes absent, distinct or connate into a calyptra, sometimes coherent and pseudocalyptrate. Stamens usually numerous , in 1 to several whorls; filaments distinct or connate into 5 bundles opposite petals; anthers 2-celled, dorsifixed or basifixed , dehiscing longitudinally or rarely terminally; connectives usually terminating in 1 or more apical glands . Ovary inferior, semi-inferior, or very rarely superior, carpels 2 to more, locules 1 to many, pseudoseptum sometimes present, placentation usually axile but occasionally parietal ; ovules 1 to several per locule. Style single; stigma single. Fruit a capsule, berry, drupaceous berry, or drupe, 1- to many-seeded. Seeds without endosperm or endosperm sparse and thin; testa cartilaginous or thinly membranous, sometimes absent; embryo straight or curved .

About 130 genera and 4500-5000 species: Mediterranean region, sub-Saharan Africa, Madagascar, tropical and temperate Asia, Australia, Pacific islands, tropical and South America; 10 genera (five introduced ) and 121 species (50 endemic, 32 introduced treated here) in China.

Many Myrtaceae are cultivated garden ornamentals , street trees, or plantation trees. Some members of tribe Syzygieae are grown as fruit crops. In addition to the cultivated members of the family treated here, some others grown in China include Acca sellowiana (O. Berg ) Burrett (Feijoa sellowiana (O. Berg) O. Berg), Myrtus communis Linnaeus, and Syncarpia glomulifera (Smith) Niedenzu.[1]

Genus Eucalyptus

Trees or shrubs . Bark smooth , fibrous , stringy, or tessellated. Leaves usually polymorphic with different juvenile and mature forms and sometimes with intermediate forms. Juvenile leaves opposite, 3 to several pairs, shortly petiolate or sessile; leaf blade often glaucous or with glandular trichomes ; juvenile foliage sometimes persisting throughout life of plant. Mature leaves alternate, petiolate; leaf blade usually leathery, secondary veins numerous , with intramarginal veins . Inflorescences axillary or clustered into terminal or axillary panicles, consisting of umbelliform condensed dichasia. Flowers bisexual . Hypanthium campanulate , obconic, or semiglobose, stipitate or not, apex usually truncate . Sepals rarely distinct . Petals connate , either adnate to sepals into a 1-layered calyptra or not adnate and then with connate sepals forming a 2-layered calyptra; calyptra deciduous at anthesis . Stamens numerous, usually distinct, in several whorls with outer whorl usually sterile ; anthers 2-celled, parallel or oblique , elliptic , ovate , cordate, or bifurcate , dehiscing longitudinally or occasionally poricidally. Ovary adnate to hypanthium, 2-7-loculed; ovules numerous. Style persistent . Whole or most of capsule included in expanded hypanthium; disk often well developed; valves exserted from hypanthium, equaling hypanthium rim, or included in hypanthium. Seeds numerous, many sterile and undeveloped , developed seeds ovate or angular; testa rigid , sometimes developed into wings .

About 700 species: mainly in Australia, with a minor representation in Indonesia, Papua New Guinea, and the Philippines; about 110 species cultivated in China with only 25 major ones treated here.

The genus is treated here in the broad sense, i.e. , the segregate Corymbia is not recognized.[2]
