Corymbia terminalis
Corymbia terminalis
Corymbia terminalis is a flowering plant in the myrtle family ( Myrtaceae ). It occurs in the north and center of Australia, where it is "Desert Bloodwood ", " Bloodwood ", " Tjuta " or " Joolta " called.
Description
Appearance and leaf
Corymbia terminalis grows as a tree, plant height reaches up to 18 meters. The bark remains on the entire tribe or even at smaller branches is gray - brown or red-brown, the lower part of the tree mat, like a chessboard and has glands. In bone marrow oil glands are present.
In Corymbia terminalis is available Heterophyllie. The leaves are always divided into petiole and leaf blade. The leaf blade of young specimens is lanceolate to ovate and has only stiff glandular hairs. The leaf blade to middle-aged plants is lanceolate to elliptic, straight, entire, and dull green. The petiole of adult specimens is narrow flattened or channel-shaped in cross section. The leaf blade of adult specimens is relatively thick, lanceolate to broad - lanceolate, falcate, with tapered Spreitenbasis and sharpened top end. Your upper leaf surface and bottom is the same color dull green. The barely visible lateral nerves go at small distances from at an obtuse angle from the midrib. On each half of the sheet, there is a strong, consistent, so-called intra- marginal nerve, it flows together with the sheet edge. The cotyledons ( cotyledons ) are nearly circular.
Inflorescence and flower
Terminally on a terete inflorescence stem is a composite inflorescence, consisting of doldigen part inflorescences, each with three to seven flowers. The flower stems are terete.
The pear - or egg-shaped flower bud is wrong floured not blue - green or frosted. The sepals form a calyptra, which up to the opening of the flower ( anthesis ) remains. The smooth calyptra conical or hemispherical and narrower than the smooth flower cup ( hypanthium ). The flowers are cream-colored.
Fruit and seeds
The stalked fruit is oval to urn shaped and vierfächerig. The disc is pressed and the fruit trays are included.
The regular or laterally flattened, barge - or egg-shaped seed has a net-like, matte to satin, red-brown seed coat. The hilum is located at the upper end of the seed.
Occurrence
The natural range of Corymbia terminalis extends from the north-western New South Wales over the central and western Queensland, northern South Australia and the entire Northern Territory to the north and the center of Western Australia.
Corymbia terminalis grows on plains and low rocky elevations in the bush and grassland or in the open forests of the Central Australian desert areas.
Taxonomy
The first description was in 1859 by Ferdinand von Mueller under the name ( basionym ) Eucalyptus terminalis F.Muell. and the title of Monograph of the Eucalypti in tropical Australia in the Journal of the Proceedings of the Linnean Society, Botany, Volume 3, page 98 The type material has the caption In partis et plantiebus siccis fertiloribus Australiae intratropicae non rara. Anth. Aestate on. The new combination to Corymbia terminalis ( F.Muell. ) KDHill & LASJohnson took place in 1995 by Kenneth D. Hill and Lawrence Alexander Sidney Johnson under the title Systematic studies in the Eucalypts. (. F.Muell ) 7 A revision of the blood woods, genus Corymbia ( Myrtaceae ) in Telopea, Volume 6, Issue 2-3, p 323 Other synonyms for Corymbia terminalis KDHill & LASJohnson are: Corymbia tumescens KDHill & LASJohnson, Corymbia opaca ( DJCarr & SGMCarr ) KDHill & LASJohnson, Eucalyptus opaca DJCarr & SGMCarr, Eucalyptus pyrophora Benth. f pyrophora, Eucalyptus orientalis DJCarr & SGMCarr, Eucalyptus pyrophora Benth., Eucalyptus pyrophora Benth. var pyrophora, Eucalyptus centralis DJCarr & SGMCarr, Eucalyptus corymbosa var terminalis ( F.Muell. ) FMBailey, Eucalyptus pyrophora f compacta Domin, Eucalyptus pyrophora var compacta Dominguez.
Corymbia terminalis forms with some other kinds of natural hybrids.
Use
In places where the bark of Corymbia terminalis peels, enters a blood-red sap from rubber, hence the English common name " Bloodwood ". The juice is crystallized and closes the wound on the tree. Aborigines use this sticky juice to treat their wounds. It is often applied to the wound and washed again. He is anti-inflammatory. Is the juice already crystallized, it can be ground, are mixed with water and used as an antiseptic wash solution. The Aborigines use the juice also for the tanning of their component kangaroo skin water bags.
Female scales rain Corymbia terminalis to the formation of plant galls. Aborigines eat these as "Bush Coconut " ( directly translated into German "bush - coconut " ) designated as bile Bushfood.
The dry wood is used by the Aborigines as firewood.
The roots store water. The Aborigines dig out the roots and collect the water in suitable containers.
The woody fruits serve the Aborigines as jewelry or children's toys.
