Corymbia intermedia is a species of plant withinthe myrtle family (Myrtaceae). It occurs on the east coast of Australia and in the adjacent Great Dividing Range to the west. It is called "Pink Bloodwood" there.
description
Appearance and leaf
Corymbia intermedia grows as a tree that reaches heights of up to 30 meters. The bark remains on the entire tree, is red-brown or gray-brown and checkerboard-like. The small twigs have a green bark. There are oil glands in the marrow, but not in the bark.
At Corymbia intermedia is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. The leaf blade on young specimens is elliptical to ovate or lanceolate and has stiff glandular hairs and sometimes simple hairs. The leaf blade on medium-old plants is elliptical to ovate, with entire margins and glossy green. The leaf stalk on adult specimens is 8 to 20 mm long. The leaf blade on adult specimens has different glossy green leaves on the top and bottom and is relatively thick, with a length of 10 to 15 cm and a width of 2 to 3 cm lanceolate to broadly lanceolate or egg-shaped, straight, with a tapering or round blade base and pointed or pointed upper end. The raised lateral nerves 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 runs at a small distance along the edge of the leaf. The cotyledons ( cotyledons ) are almost circular.
Inflorescence and flower
At the end of an inflorescence stem with a length of 10 to 18 mm in cross-section is a compound inflorescence , which consists of dold-like partial inflorescences with about seven flowers each. The flower stalk is 2 to 14 mm long in cross section with a round stem.
The not blue-green floured or frosted flower bud is egg to pear-shaped with a length of 6 to 8 mm and a diameter of 3 to 4 mm. The sepals form a calyptra that remains in place until flowering ( anthesis ). The smooth calyptra is hemispherical or conical, narrower than the smooth flower cup (hypanthium) and shorter than this. The flowers are white or cream in color.
Fruit and seeds
The stalked fruit is 10 to 21 mm long and 8 to 16 mm in diameter, egg-shaped to urn-shaped and three to four-fold. The disc is indented, the fruit compartments are included.
The regular and 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 intermedia extends on the east coast of Australia along from Gloucester in northeastern New South Wales to Cooktown in Queensland . Corymbia intermedia can also be found on the adjacent eastern roof of the Great Dividing Range .
Corymbia intermedia grows preferentially and locally predominantly in coastal forests, on moderately fertile soils .
Taxonomy
It was first described in 1901 by Richard Thomas Baker under the name ( Basionym ) Eucalyptus intermedia R.T.Baker in Proceedings of the Linnean Society of New South Wales , Volume 25, p. 674, Plate XLVI, Fig. 1. The type material has the inscription “ Ballina (W. Bäuerlen), Richmond and Clarence Rivers (Rev. Dr. Woolls), Barney's Wharf, Cambewarra, (W. Bäuerlen, P. Macpherson) ”. The specific epithet intermedia is derived from the Latin word intermedius for temporarily stored and refers to the properties of eucalyptus oil that lie between those of "Red Bloodwood" ( Corymbia gummifera ) and those of "Yellow Bloodwood" ( Corymbia eximia ). The new combination to Corymbia intermedia (RTBaker) 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 (2-3), p. 247. Another synonym for Corymbia intermedia (RTBaker) KDHill & LASJohnson is Eucalyptus gummifera var. Intermedia (RTBaker) Domin .
use
The color of the heartwood varies from dusky pink to deep red to red-brown and its specific weight is around 1010 kg / m³. Like that of Corymbia gummifera and Corymbia polycarpa , the wood is used, for example, to make beams, railway sleepers. Hardboard and fences. Sawdust can irritate the eyes.
The English common name is derived from the wood color, which can be traced back to the resin nerves.
