description
Appearance and leaf
Eucalyptus melliodora grows as a tree that reaches heights of up to 30 meters. The bark remains on the lower part of the trunk or on the entire trunk and the larger branches, is gray, pale brown or yellow-brown with white spots and fibrous-lumpy. On the upper parts of the tree it is gray, gray-brown or yellow and peels in short ribbons. The small twigs have a green bark. There are no oil glands in the marrow of the young branches or in the bark.
In Eucalyptus melliodora , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. The leaf stalks are 10 to 15 mm long. The leaf blade on young specimens is elliptical and dull green or gray-green. In medium-old specimens, the leaf blade is about 11 cm long and about 5 cm wide, elliptical, straight, with entire margins and dull green or gray-green. The leaf blades of the same color on the upper and lower sides of the adult specimens are dull green or gray-green and are 6 to 14 cm long and 0.8 to 1.8 cm wide, narrow-lanceolate or lanceolate, curved sickle-shaped, tapering towards the Spread base and have a pointed upper end. The side nerves, which are barely recognizable, extend from the median nerve at large intervals at an acute angle. The cotyledons ( cotyledons ) are upside-kidney-shaped.
Inflorescence and flower
On the side of a pedicel-round, narrowly flattened or angular inflorescence stem with a length of 3 to 11 mm and a diameter of up to 3 mm in cross section, there are about seven flowers together in a simple inflorescence . The 2 to 9 mm long pedicels are stalk-round. The not blue-green floured or frosted flower buds are club-shaped or egg-shaped with a length of 5 to 8 mm and a diameter of 3 to 4 mm. The sepals form a calyptra that remains in place during the opening of the flower ( anthesis ). The smooth calyptra is conical and sometimes also beak-shaped, as long as or shorter than the smooth or ribbed flower cup (hypanthium) and as wide as or narrower than this. The outer stamens are sterile. The flowers are white or creamy white.
fruit
The stalked fruit is spherical, hemispherical or egg-shaped and five-fan with a length and a diameter of 4 to 7 mm each. The disc is indented, the fruit compartments are included.
Occurrence
The natural range of Eucalyptus melliodora is the Great Dividing Range in southeast Queensland , east and central New South Wales , and north, east and south of Victoria .
Eucalyptus melliodora grows widespread and locally often in grassy, sparse forests on moderately fertile soils , often on sandy soils or in valleys of watercourses.
Systematics
The first description of Eucalyptus Melliodora was carried out in 1843 by John Konrad Schauer in repertory Botanices Systematicae , Volume 2 (5), p 924. The type material , the label " In Novae Cambriae australis plagis interioribus occidentum versus frequens on". The specific epithet melliodora is composed of the Latin words “mel” for honey and “odor” for smell.
