description
Appearance and leaf
Eucalyptus acmenoides grows as a tree that reaches heights of up to 30 meters, sometimes up to 50 meters. The bark remains on the entire tree, is gray to red-brown, thin and fibrous. The small branches are green. There are no oil glands in the marrow or in the bark.
In Eucalyptus acmenoides , heterophyllia is present. The leaves on young specimens are broadly lanceolate and shiny green. The glossy leaves on adult specimens, which are green on top and bottom, are divided into a petiole and a leaf blade. The 8 to 15 mm long petioles on adult specimens are narrowly flattened or channel-shaped in cross section. The leaf blade on adult specimens is crescent-shaped and broadly lanceolate with a length of 8 to 12 cm and a width of 1.5 to 2.5 cm with a pointed, blunt or tapering blade base. The lateral nerves come off the median nerve at medium distances at acute or obtuse angles.
Inflorescence and flower
On a cross-section angular, 6 to 15 mm long inflorescence stem, seven to eleven or more flowers stand together in a single inflorescence . The pedicel-round flower stalk is 2 to 6 mm long. The flower buds are ovoid or spindle-shaped with a length of 5 to 7 mm and a diameter of 3 to 4 mm. The calyptra is conical and at least as long and as wide as the smooth flower cup (hypanthium). According to EucaLink, the calyptra can also be oblong-pointed and two to three times as long as the smooth flower cup. The flowers are white or creamy white.
fruit
The fruit is hemispherical with a length of 4 to 8 mm and a diameter of 4 to 7 mm. The disc is narrow, indented or flat, and the fruit compartments are enclosed or level with the rim.
Occurrence
Eucalyptus acmenoides occurs along the east coast of Australia from north Queensland down to the area north of Sydney in the central coastline of New South Wales.
It grows in moist hardwood or sparse forests and occurs frequently in places. Eucalyptus acmenoides thrives best in deeper soils with medium nutrient levels and regular moisture.
Taxonomy
The first description of eucalyptus acmenoides was made in 1843 by the German botanist Johannes Conrad Schauer in Wilhelm Gerhard Walpers : Repertory Botanices Systemaicae , Volume 2 (5), p 924. This type of material has the inscription " In Sylvis Novae Cambriae australis ( A.Cunn. ) " on. According to Joseph Henry Maiden , the specific epithet acmenoides indicates the similarity of the shape of the leaves with that of Acmena smithii , a synonym of Syzygium smithii (see photo of the leaves, above).
Synonyms for Eucalyptus acmenoides Schauer are: Eucalyptus pilularis var. Acmenoides (Schauer) Benth. , Eucalyptus acmenoides Schauer var. Acmenoides , Eucalyptus uvida K.D.Hill , Eucalyptus portutensis K.D.Hill , Eucalyptus contracta L.AS Johnson & KDHill , Eucalyptus acmenioides showers orth. Var.
Eucalyptus acmenoides forms hybrids with other species, for example Eucalyptus cloeziana , Eucalyptus pilularis , Eucalyptus eugenioides .
use
The heartwood of Eucalyptus acmenoides is yellow-brown, very hard and has a specific weight of around 1010 kg / m³. The wood is used as construction and furniture wood and for building boats and wagons. It is used, for example, for the construction of piers and walkways , for the manufacture of railway sleepers , floors and cladding .
