Eucalyptus polyanthemos is a species ofthe myrtle family (Myrtaceae). It occurs in the east and south-east of New South Wales as well as in the east, in the south and in the center of Victoria and is called there "Poplar Box" or "Red Box".
description
Appearance and leaf
Eucalyptus polyanthemos grows as a tree that can reach heights of up to 20 or 25 meters. The bark is smooth or remains on the lower part of the trunk or on the entire trunk and the larger branches. It is gray with whitish spots and fibrous and lumpy. 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 the small branches is green. There are no oil glands in the marrow of the young branches or in the bark.
In Eucalyptus polyanthemos is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. The leaf blades on seedlings are 2.5 to 6 cm long and 2 to 7 cm wide, more or less circular, often wider than long and the same color blue-green on the top and bottom. On young specimens, the leaf blade is 5 to 6.5 cm long and 5 to 8 cm wide, also circular, usually wider than long, often notched, and floured or frosted on the top and bottom of the same color, matt gray-green or blue-green . On medium-old specimens, the leaf blade is 6 to 9 cm long and 3.5 to 5 cm wide and is egg-shaped or circular, straight, with entire margins and matt gray-green or blue-green floured or frosted. The leaf stalks on adult specimens are 15 to 25 mm long and narrowly flattened or channel-shaped. The leaf blades on adult specimens are dull gray-green or blue-green floured or frosted in the same color on the top and bottom and are relatively thick, straight, with a length of 4 to 9 cm and a width of 1.5 to 3.5 cm wide-lanceolate elliptical or egg-shaped, with a pointed, blunt, rounded or notched upper end and tapering towards the base of the blade. The raised lateral nerves extend from the median nerve at large intervals at an acute or very acute angle. The cotyledons ( cotyledons ) are upside-kidney-shaped.
Inflorescence and flower
Terminally or laterally on an inflorescence stem with a length of 5 to 15 mm in cross-section with a round pedicel are in compound total inflorescences about seven-flowered partial inflorescences . The inflorescence stem and the flower stalks are often floured or frosted blue-green. The flower stalks are 1 to 9 mm long and stalk-round 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 that falls off 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 creamy white. The flowering period extends from September to December at the home locations.
Fruit and seeds
With a length of 4 to 7 mm and a diameter of 3 to 6 mm, the stalked fruit is hemispherical, conical, cylindrical, pear-shaped or conversely conical, sometimes also floured or frosted blue-green and three- to fourfold. The disc is indented, the fruit compartments are included.
The seeds with a brown seed coat are slightly depressed. The hilum sits in the middle.
ecology
The larvae of the moth species Trichiocercus sparshalli and the "Eucalyptus Leaf Mining Sawfly" ( Phylacteophaga froggatti ) feed on the leaves of Eucalyptus polyanthemos . Large, old trees are often hollow and serve as nests for owls, for example the "Barking Owl" ( Ninox connivens ).
Occurrence
The natural range of Eucalyptus polyanthemos is the east and southeast of New South Wales , south of Gulgong with small occurrences in the upper Hunter Valley , as well as in the east, in the south and in the center of Victoria .
Eucalyptus polyanthemos thrives widely in grassy or hardwood forests on light, flat soils .
Systematics
The first description of Eucalyptus polyanthemos was made 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 ab urbe Bathurst (A. Cunn. Herb. No . 136/1822) ". Synonyms for Eucalyptus polyanthemos Schauer are Eucalyptus ovalifolia R.T.Baker , Eucalyptus ovalifolia R.T.Baker var. Ovalifolia and Eucalyptus ovalifolia var. Lanceolata R.T.Baker & HGSm. The specific epithet polyanthemos is derived from the ancient Greek words poly for much and anthemon for flower and refers to the many-flowered inflorescences.
Of Eucalyptus polyanthemos there are four subspecies:
- Eucalyptus polyanthemos subsp. longior Brooker & Slee
- Eucalyptus polyanthemos subsp. marginalis rule , syn. Eucalyptus polyanthemos shower subsp. polyanthemos
- Eucalyptus polyanthemos shower subsp. polyanthemos : bark mostly smooth, peels in large patches, sometimes remains irregularly on the trunk.
- Eucalyptus polyanthemos subsp. vestita L.ASJohnson & KDHill : Bark remains on the trunk and the larger branches.
Well-known single copies
In Gilmore in the Australian Capital Territory there is a specimen of Eucalyptus polyanthemos called "Murumbeeja Scarred Red Box No 1". It is recorded in the Register of the National Estate. The bark was removed from him by Aborigines , presumably to make canoes from it.
use
The heartwood of Eucalyptus polyanthemos is red, hard and moderately persistent. It has a specific weight of 950–1115 kg / m³. The wood from Eucalyptus polyanthemos is used to build fences and makes excellent firewood.
Eucalyptus polyanthemos is used as an ornamental plant on streets and in parks. The branches with leaves from young specimens are used as cut green in floristry .
