Appearance and leaf

Eucalyptus microcorys grows as a tree that can reach heights of up to 40 meters, occasionally up to 60 meters. The bark remains on the entire tree, is red-brown or brown-black and fibrous with mica-like spots. The bark of the small branches is green. There are no oil glands in the marrow of the young branches or in the bark.

In Eucalyptus microcorys , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. The leaf blade on seedlings is slightly differently colored on the top and bottom and is egg-shaped with a length of 4.5 to 7 cm and a width of 2 to 3.3 cm. On young specimens, the leaf blade is egg-shaped with a length of 7 to 11 cm and a width of 3 to 5 cm and shiny green in different colors on the top and bottom. On medium-old specimens, the leaf blade is 8.5 to 15 cm long and 2.5 to 4 cm wide, elliptical to ovate, straight, with entire margins and shiny green. The petiole on adult specimens is 6 to 18 mm long and narrowly flattened or channel-shaped. The leaf blade on adult specimens is glossy green in different colors on the top and bottom and is 8 to 13 cm long and 1.5 to 2.5 cm wide, lanceolate, relatively thin and tapers towards the base of the blade. The leaf blade can be curved straight or sickle-shaped and its upper end can be pointed or pointed. The raised lateral nerves depart from the median nerve at intermediate intervals at an obtuse angle. The cotyledons ( cotyledons ) are kidney-shaped.

Inflorescence and flower

End or lateral are often in several at the end of the branches, on a with a length of 6 to 18 mm in cross-section narrowly flattened or angular inflorescence stem simple inflorescences that contain seven to eleven flowers. The flower stalks are 2 to 6 mm long with round or angular stems. The flower buds are club-shaped with a length of 4 to 6 mm and a diameter of 2 to 3 mm and are not floured or frosted blue-green. The sepals form a calyptra , which is preserved until flowering ( anthesis ). The smooth calyptra with four seams is hemispherical, shorter than or as long as the smooth or slightly ribbed flower cup (hypanthium) and as wide as this. The flowers are white or creamy white. The flowering period extends from August to December.

Fruit and seeds

With a length of 5 to 9 mm and a diameter of 4 to 6 mm, the stalked fruit is conical, pear-shaped, or inverted conical, finely ribbed or striped and triple, sometimes quadruple. The disc is indented, the fruit compartments are more or less level with the rim.

The yellow-brown seed is ellipsoidal and has a honeycomb structure. The hilum is in the middle.

Occurrence

The natural range of Eucalyptus microcorys is the central and northern coastal region of New South Wales including the hinterland, essentially north of Sydney , as well as the subsequent, southern coastal region from Queensland to Rockhampton in the north.

There is also a singular occurrence in the southwest of Western Australia . This occurrence in the independent administrative district of Augusta-Margaret River in the South West region is considered untypical. The specimens there with rough, gray bark reach heights of growth of 5 to 12 meters. Eucalyptus microcorys is drought and frost resistant.

Eucalyptus microcorys is very common in moist forests and on the edges of rainforests , often on slopes, on moderately to very fertile soils . The population in Western Australia is found on brown loam soils over laterite and on clay soils in light secondary forest and along watercourses.

Taxonomy

The first description of eucalyptus microcorys was in 1860 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae , Volume 2 (12), p 50. The type material , the label " In silvis ad flumina Hastings et McLeay River. Dr. Beckler. Ad flumen Brisbane. FM ”. The specific epithet microcorys is composed of the ancient Greek words micros for small and corys for helmet or cap and refers to the calyptra.

use

The heartwood of Eucalyptus microcorys is yellow-brown with a slightly greenish tinge, a greasy appearance and extremely resistant. It is also known as tallow wood .

It has a specific weight of 875-1065 kg / m³. The timber from Eucalyptus microcorys is used as heavy construction timber for the manufacture of posts , railroad ties, cross braces , floors and decks . It is considered to be one of the finest native hardwoods in New South Wales.
