Description
Appearance and leaf
Eucalyptus cloeziana grows as a tree, the plant height of 10 to 35 meters, in the Gympie region and up to 55 meters, is reached. The bark remains on the entire tribe or even the smaller branches, is pale brown, yellow-brown, gray-brown or brown and cradled. Both in the marrow of the young branches as well as in the bark, there are oil glands.
In Eucalyptus cloeziana is available Heterophyllie. The leaves are almost always divided into petiole and leaf blade. Only at seedlings are the first five to nine pairs of leaves against constantly and sitting or only short-stalked. The on top and bottom in different colors gray - green leaf blade of seedlings are elliptic to ovate with a length of 6 to 10 inches and a width of 2 to 5 centimeters. In young specimens on bottom and top in different colors green leaf blade is ovate to broadly lanceolate with a length of 9 to 15 cm and a width of 2.5 to 7 inches. At middle-aged specimens, the dull gray - green leaf blade with a length of 10 to 15 centimeters and a width of 3 to 4 centimeters wide - lanceolate to lanceolate, curved like a sickle and entire. Sometimes the leaves of medium old specimens may be sitting. The on top and bottom in different colors matt green leaf blades of adult specimens are lanceolate with a length of 8 to 13 centimeters and a width of 1 to 3 centimeters, to narrow - lanceolate relatively thin, curved like a sickle, tapering to the Spreitenbasis and has a pointed top end. The barely visible lateral nerves go off at an obtuse or acute angle from the midrib.
Inflorescence and flower
Constantly on a page with a length of 5 to 10 millimeters and a diameter of up to 3 mm in cross section terete, narrowly flattened or angular inflorescence stem are about siebenblütige part inflorescences in total composite inflorescences. The flower stalks are 1-4 mm long. The non- blue-green floured or frosted flower buds are ovoid or club-shaped with a length of 4 to 7 mm and a diameter of 3 to 4 millimeters. The sepals form a calyptra, which drops early. The smooth calyptra is hemispherical, as long and as wide as the smooth flower cup ( hypanthium ). The flowers are white or off- white. The flowering period extends from November to February.
Fruit and seeds
The short- stemmed crop is spherical with a length of 5 to 10 mm and a diameter of 6 to 12 mm or hemispherical and three to vierfächrig. The disc is flat or slightly raised, the fruit trays are at the height of the edge or protrude slightly.
The yellow -brown seed is cubic or elongated. The hilum is located on the top end.
Occurrence
The natural range of Eucalyptus is cloeziana east coast of Queensland from Brisbane to Mackay and Townsville to Cooktown and the adjacent Great Dividing Range from Gympie to Barcaldine.
System
The first description of Eucalyptus cloeziana took place in 1878 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae, Volume 11, 89, 44 S. The type material has the inscription " In montibus orariis ad Rockingham Bay; Dallachy "on. The specific epithet cloeziana reminiscent of the French pharmacists ' F. S. Cloez " (1817-1883), which dealt with the distillation of eucalyptus oil from the leaves. A synonym of Eucalyptus cloeziana F.Muell. Eucalyptus is stannariensis F.M.Bailey.
There are natural hybrids of Eucalyptus Eucalyptus cloeziana with acmenoides.
Use
The heartwood of Eucalyptus cloeziana is yellowish - brown and extremely resistant. It has a specific gravity of 855-1140 kg / m³. The wood of Eucalyptus cloeziana is used as a heavy timber, such as railroad ties, mining, for piles, columns and rafters.
