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]
Habitat
Typically found at an altitude of 0 to 759 meters (0 to 2,490 feet).[3]
