Eucalyptus carnea is a species ofthe myrtle family (Myrtaceae). It occurs on the east coast of Australia from eastern New South Wales to southeastern Queensland and is called "Thick-leaved Mahogany" there.
description
Appearance and leaf
Eucalyptus carnea grows as a tree that reaches heights of up to 30 meters. The thin bark remains on the entire tree, is gray to red-brown and fibrous. The small twigs have a green bark. There are no oil glands in the marrow or in the bark.
In Eucalyptus carnea , heterophyllia is present. The leaves on young specimens are broadly lanceolate, curved sickle-shaped and dull gray-green. On medium-old specimens, the stalked leaves are about 15 centimeters long and about 1 centimeter wide, lanceolate, straight, with entire margins and shiny green. The leaf stalks on adult specimens are narrowly flattened or channel-shaped with a length of 10 to 22 millimeters. The leaf blades of the same color on the upper and lower sides on adult specimens are lanceolate or broadly lanceolate, with a length of 6 to 18 centimeters and a width of 1.5 to 4.0 centimeters, relatively thick, sickle-shaped, curved at the The base of the blades is blunt and has a pointed upper end. The side nerves, which are barely recognizable, extend from the median nerve at medium intervals at an acute or obtuse angle. The cotyledons ( cotyledons ) are kidney-shaped.
Inflorescence and flower
On a 9 to 25 millimeter long inflorescence stem, which is narrowly flattened or angular in cross section, there are seven to eleven flowers in a single inflorescence . The flower stalk is 3 to 7 millimeters long and angular. The not blue-green floured or frosted flower buds are egg-shaped or spindle-shaped with a length of 6 to 9 mm and a diameter of 3 to 4 millimeters. The sepals form a calyptra that remains in place until flowering ( anthesis ). The smooth calyptra is conical to beak-shaped, twice or as long as the smooth flower cup (hypanthium) and narrower than this. The flowers are white or creamy white.
fruit
The stalked fruit is 5 to 8 millimeters long and 5 to 9 millimeters in diameter hemispherical and three- to five-fan. The disc is flat and narrowly indented or raised, the fruit compartments are level with the rim.
Occurrence
The natural range of Eucalyptus carnea is the east coast of Australia from Sydney in New South Wales to Bundaberg in Queensland and the subsequent eastern slopes of the Great Dividing Range .
Eucalyptus carnea grows widespread and often in dry hard- deciduous forests on flat clay soils over slate .
Taxonomy
The first description of Eucalyptus carnea was made in 1906 by Richard Thomas Baker in Proceedings of the Linnean Society of New South Wales , Volume 31, page 303, Table XXIII. The type material has the inscription “ Wadell; Dunoon, Richmond River; Lismore (W. Bäuerlen) ”. The specific epithet carnea is derived from the Latin word carneus for flesh-colored and refers to the color of the heartwood. Synonyms for Eucalyptus carnea R.T.Baker are: Eucalyptus acmenoides var. Carnea (RTBaker) Maiden . Eucalyptus umbra subsp. carnea (RTBaker) LASJohnson , Eucalyptus acmenioides var. carnea Maiden orth. var., Eucalyptus triantha var. carnea Domin nom. illegal.
use
The heartwood of Eucalyptus carnea is pink-brown, hard and has a specific weight of around 925 kg / m³. The timber is, like that of eucalyptus acmenoides used as construction and furniture wood for the boat and wagon construction. It is used, for example, for the construction of piers and walkways, for the manufacture of railway sleepers, floors and cladding.
