Eucalyptus polyanthemos

Eucalyptus polyanthemos subsp. vestita

Eucalyptus polyanthemos is a flowering plant within the myrtle family ( Myrtaceae ). She comes to the east and south-east of New South Wales and to the east, the south and in the center of Victoria before and is there " Poplar Box" or " Red Box " called.

Description

Appearance and leaf

Eucalyptus polyanthemos grows as a tree reaching heights of growth of up to 20 or 25 meters. The bark is smooth or remains at the lower part of the stem or the entire trunk and larger branches. She is gray with whitish spots and fibrous integrally. On the upper parts of the tree it is smooth, white or gray and peels in short ribbons or small, polygonal patches. The bark of young branches is green. Neither in the marrow of the young branches still in the bark, there are oil glands.

In Eucalyptus polyanthemos is available Heterophyllie. The leaves are always divided into petiole and leaf blade. The leaf blade of seedlings are more or less circular, often wider than long and at top and bottom of the same color blue green with a length of 2.5 to 6 cm and a width of 2-7 cm. In young specimens the leaf blade is at a length of 5 to 6,5 cm and a width of 5 to 8 cm also circular, usually broader than long, often notched and on top and bottom mat floured same color gray - green or blue- green or frosted. At middle-aged specimens, the leaf blade is at a length of 6-9 cm and a width of 3.5 to 5 cm ovoid or circular, straight, entire, floured and dull gray - green or blue- green or frosted. The petioles of adult specimens are 15-25 mm long and narrow flattened or channel-shaped. The on top and bottom of the same color dull gray - green or blue- green floured or frosted leaf blade of adult specimens is relatively thick, straight, with a length of 4 to 9 cm and a width of 1.5 to 3.5 cm wide, lanceolate to elliptic or ovate, with an acute, obtuse, rounded or notched top and tapering towards Spreitenbasis. The raised lateral nerves go at large distances from an acute or very acute angle from the midrib. The cotyledons ( cotyledons ) are wrong - kidney-shaped.

Inflorescence and flower

End or pendant on a terete with a length of 5 to 15 mm in cross section inflorescence stem are about siebenblütige part inflorescences in total composite inflorescences. The inflorescence stem and flower stems are often floured blue green or frosted. The flower stalk is 1-9 mm long and terete or angular. The often blue-green floured or frosted flower buds are egg -, club- or short spindle-shaped with a length of 4 to 6 mm and a diameter of 2 to 4 mm. The sepals form a calyptra, which drops early. The smooth calyptra is hemispherical or conical, shorter than or as long as the smooth flower cup ( hypanthium ) and narrower than this. The flowers are white or off- white. The flowering period extends to the home sites from September to December.

Fruit and seeds

The stalked fruit is hemispherical with a length of 4 to 7 mm and a diameter of 3 to 6 mm, conical, cylindrical or pear-shaped vice versa conical, sometimes floured blue green or frosted and three to vierfächrig. The disc is pressed, the fruit trays are included.

The seeds with brown seed coat are lightly pressed. The hilum is centered.

Ecology

The larvae of the moth Trichiocercus saving halli and the " Eucalyptus Leaf Mining Sawfly " ( Phylacteophaga froggatti ) feed on the foliage leaves of Eucalyptus polyanthemos. Large, old trees are often hollow and serve as nests owls, such as the " Barking Owl" ( Ninox connivens ).

Occurrence

The natural range of Eucalyptus polyanthemos the east and southeast of New South Wales, south of Gulgong with small deposits in the upper Hunter Valley, as well as in the East, in the south and in the center of Victoria.

Eucalyptus polyanthemos thrives widely used often in grassy or sclerophyll forests on easy, flat bottoms.

System

The first description of Eucalyptus polyanthemos in 1843 by Johannes Conrad Schauer in repertory Botanices Systematicae, Volume 2, Issue 5, pp. 924 The type material has the inscription " In Nova Cambriae Australis interioribus septentriones versus urbe from Bathurst (A. Cunn. Herb. No. 136/1822) "on. Synonyms for Eucalyptus Eucalyptus polyanthemos showers are ovalifolia RTBaker, Eucalyptus ovalifolia RTBaker var ovalifolia and Eucalyptus ovalifolia var lanceolata RTBaker & DDWM .. The specific epithet is polyanthemos from the Ancient Greek words poly for much and anthemon derived for flower and refers to the multi-flowered inflorescences.

From Eucalyptus polyanthemos there are four subspecies:

• Eucalyptus polyanthemos subsp. longior Brooker & Slee
• Eucalyptus polyanthemos subsp. marginalis Rule, Syn Eucalyptus polyanthemos Schauer subsp. polyanthemos
• Eucalyptus polyanthemos Schauer subsp. polyanthemos: bark mostly smooth, peels off in large patches, sometimes remains irregularly on the trunk.
• Eucalyptus polyanthemos subsp. vestita LASJohnson & KDHill: bark remains on the trunk and larger branches.

Known single copies

In Gilmore in the Australian Capital Territory is a copy of Eucalyptus polyanthemos called " Scarred Murumbeeja Red Box No. 1." He is listed in the " Register of the National Estate". For him, the bark has been removed by Aborigines, presumably to build from canoes.

Use

The heartwood of Eucalyptus polyanthemos is red, hard and moderately resistant. It has a specific gravity of 950-1115 kg / m³. The wood of Eucalyptus polyanthemos is used for the construction of fences and serves as an excellent firewood.

Eucalyptus polyanthemos is used as an ornamental plant on streets and in parks. The branches with foliage leaves of young specimens are used as greenery in floristry.
