Corymbia terminalis is a species ofthe myrtle family (Myrtaceae). It occurs in the north and in the center of Australia and is called "Desert Bloodwood", "Bloodwood", "Tjuta" or "Joolta" there.
description
Appearance and leaf
Corymbia terminalis grows as a tree that reaches heights of up to 18 meters. The bark remains on the entire trunk or on smaller branches, is gray-brown or red-brown, in the lower part of the tree is dull, checkerboard-like and has glands. There are oil glands in the medulla.
In Corymbia terminalis , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. The leaf blade on young specimens is lanceolate to ovate and has only stiff glandular hairs. The leaf blade on medium-old plants is lanceolate to elliptical, straight, entire and dull green. The petiole on adult specimens is narrowly flattened or channel-shaped in cross section. The leaf blade on adult specimens is relatively thick, lanceolate to broadly lanceolate, sickle-shaped, with a tapering blade base and a pointed upper end. The top and bottom of the leaves are matt green of the same color. The side nerves, which are barely recognizable, leave the median nerve at small intervals at an obtuse angle. On each half of the leaf there is a pronounced, continuous, so-called intramarginal nerve, it flows together with the leaf margin. The cotyledons ( cotyledons ) are almost circular.
Inflorescence and flower
At the end of a pedicel-round inflorescence stem stands a compound inflorescence , which consists of doldy partial inflorescences with three to seven flowers each. The flower stalks are stalk-round.
The pear-shaped or obovate flower bud is not floured or frosted blue-green. The sepals form a calyptra that remains until the flower ( anthesis ) opens. The smooth calyptra is conical or hemispherical and narrower than the smooth flower cup (hypanthium). The flowers are cream-colored.
Fruit and seeds
The stalked fruit is egg-shaped to urn-shaped and quadruple. The disc is indented and the fruit compartments are included.
The regular or laterally flattened, boat-shaped or egg-shaped seed has a net-like, matt to silk-matt, red-brown seed coat. The hilum is at the top of the seed.
Occurrence
The natural range of Corymbia terminalis extends from northwestern New South Wales over 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 grasslands or in the light forests of the central Australian desert areas.
Taxonomy
It was first described in 1859 by Ferdinand von Mueller under the name ( Basionym ) Eucalyptus terminalis F. Muell. and the title Monograph of the Eucalypti in tropical Australia in the Journal of the Proceedings of the Linnean Society, Botany , Volume 3, p. 98. The type material is labeled 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. 7. A revision of the bloodwoods, genus Corymbia (Myrtaceae) in Telopea , Volume 6, Issue 2-3, p. 323. Other synonyms for Corymbia terminalis (F. Muell.) KDHill & LASJohnson are: Corymbia tumescens K.D.Hill & LASJohnson , Corymbia opaca (DJCarr & SGMCarr) KDHill & LASJohnson , Eucalyptus opaca D.J.Carr & SGMCarr , Eucalyptus pyrophora Benth. f. pyrophora , Eucalyptus orientalis D.J.Carr & SGMCarr , Eucalyptus pyrophora Benth. , Eucalyptus pyrophora Benth. var. pyrophora , Eucalyptus centralis D.J. Carr & SGMCarr , Eucalyptus corymbosa var. terminalis (F. Muell.) FMBailey , Eucalyptus pyrophora f. compacta Dominguez , Eucalyptus pyrophora var. compacta Dominguez .
Corymbia terminalis forms natural hybrids with several other species .
use
In places where the bark of Corymbia terminalis peels off, a blood-red rubber sap emerges, hence the common name "Bloodwood". The sap crystallizes and closes the wound on the tree. Aboriginal people use this sticky sap to treat their wounds. It is often applied to the wound and washed off again. So it has an anti-inflammatory effect. If the juice has already crystallized out, it can be ground, mixed with water and used as an antiseptic washing solution. The Aborigines also use the sap to tan their kangaroo skin water sacs.
Female scale insects stimulate Corymbia terminalis to form plant galls. Aborigines eat this as “Bush Coconut” (translated directly into German “Bush Coconut”) as Bush Food .
The dry wood is used by the Aborigines as firewood.
The roots store water. The Aborigines dig up the roots and collect the water in suitable vessels.
The woody fruits serve the Aborigines as jewelry or children's toys.
