description
Appearance and leaf
Eucalyptus melanophloia grows as a tree that can reach heights of up to 20 meters. The bark remains on the entire tree, is gray-black and rounded ("ironbark"). The small twigs have a green bark. There are oil glands in the pith of the young branches, but not in the bark.
In eucalyptus melanophloia is Heterophyllie ago. On young specimens, the leaves are egg-shaped to circular and blue-green floured or frosted. In medium-old specimens, the sitting leaves are egg-shaped to circular, straight, with entire margins and blue-green floured or frosted with a length and width of about 10 cm each. The blue-green floured or frosted, opposite leaves on adult specimens with the same colored upper and lower sides are broad-lanceolate, egg or heart-shaped, relatively thick, with a length of 5 to 9 cm and a width of 2.0 to 3.5 cm, straight, tapering towards the base of the blade and having a blunt or rounded upper end. The side nerves, which are barely recognizable, extend from the median nerve at medium intervals at an acute or obtuse angle. If available, petioles up to 3 mm long are stalk-round, narrowly flattened or angular. The cotyledons ( cotyledons ) are upside-kidney-shaped.
Inflorescence and flower
Lateral or terminal at a mm and a length of 4 to 16 to a diameter of up to 3 mm in cross-section round stalk, narrow-edged flattened or inflorescence stem are in composite total inflorescences irregularly about siebenblütige part inflorescences. The 1 to 7 mm long flower stalks are stalk-round. The blue-green floured or frosted flower buds are short spindle-shaped with a length of 7 to 9 mm and a diameter of 3 to 5 mm. The sepals form a calyptra that falls off early. The smooth calyptra is conical, once or twice as long as the smooth or ribbed flower cup (hypanthium) and as wide as or narrower than this. All stamens are fertile (fertile). The flowers are white or creamy white.
fruit
The stalked fruit is spherical, hemispherical, egg-shaped or urn-shaped and quadruple with a length and a diameter of 3 to 8 mm each. The disc is pressed in, the fruit compartments are level with the edge or protrude.
Occurrence
The natural range of Eucalyptus melanophloia is the north and northeast of New South Wales , north of Dubbo , as well as the east and the center of Queensland and the center of the Northern Territory .
Eucalyptus melanophloia grows widespread and often in hard-leaf or grassy forests on lighter soils .
Systematics
The first description of eucalyptus melanophloia in 1859 by Ferdinand von Mueller , entitled Monograph of the Eucalypti of tropical Australia in the Journal of the Proceedings of the Linnean Society, Botany , Volume 3, page 93. A synonym of eucalyptus melanophloia F.Muell. is Eucalyptus melanophloia F. Muell. var. melanophloia .
Natural hybrids forms eucalyptus melanophloia with Eucalyptus coolabah , eucalyptus crebra , Eucalyptus cullenii , Eucalyptus decorticans , Eucalyptus leptophleba , Eucalyptus microtheca , Eucalyptus orgadophila , Eucalyptus populnea , Eucalyptus whitei and Eucalyptus xanthoclada .
From Eucalyptus melanophloia F. Muell. there are two to three subspecies:
- Eucalyptus melanophloia F. Muell. subsp. melanophloia
- Eucalyptus melanophloia subsp. nana D. Nicolle & Kleinig
- Eucalyptus melanophloia subsp. × senta Blakely
