Eucalyptus viminalis

Rod -shaped eucalyptus

The rod- shaped (Eucalyptus viminalis ) is a flowering plant in the myrtle family ( Myrtaceae ). It occurs in a wide belt along the coast of southeastern Australia and Tasmania, where it is called " Manna Gum", " Ribbon Gum" or " White Gum ".

Description

Appearance and leaf

The rod- shaped eucalyptus grows as a tree, the growth heights of up to 30 meters, sometimes 50 meters, achieved. The bark is smooth on the whole tree, or remains at the lower part of the stem is gray to gray-black, and short-fibred. On the upper parts of the tree, the bark is smooth, white, yellow or gray and peels in long strips. The small branches are green. Oil glands are there in the bark, but not in Mark. The bark of the branches is green.

When rod -shaped eucalyptus is Heterophyllie ago. The leaves of young specimens are opposite, lanceolate, entire, dull green. The opposite, dull green leaves on medium old specimens do not have petioles and are lanceolate, straight, entire, with a length of about 15 cm and a width of about 0.3 cm. The leaf stalks of adult specimens are narrow - flattened in cross-section or channel- shaped, and from 10 to 25 mm long. The single-color, glossy green leaf blades of adult specimens are sickle-shaped with a length of 8 to 20 cm and a width of 0.8 to 2.5 cm, narrow - lanceolate to lanceolate, with tapered and rounded Spreitenbasis or ausgerandetem upper end. The raised lateral nerves go with average distances from a pointed or obtuse angle from the midrib.

Inflorescence and flower

Constantly on a side cross-sectional narrow - flattened or angular, 4-8 mm long inflorescence stem are only about three flowers in a simple inflorescence. The outer stamens are infertile. The flowers are white or cream-colored. The stalk round flower stalk is hard to detect and most up to 3 mm long. The non- blue-green frosted or floured flower bud is oval with a length of 5 to 8 mm and a diameter of 3 to 5 mm. The sepals form an early falling " calyptrata " or " operculum ". The smooth calyptra conical or hemispherical and at least as long and wide as the smooth flower cup ( hypanthium ). The flowers are white or cream-colored.

Fruit

The pedunculated or sedentary fruit is globose, ovoid or cylindrical, with three or four fruit trays at a length of 4 to 8 mm and a diameter of 4-9 mm. The discus is raised and the fruit trays protrude.

Ecology

Eucalyptus viminalis is widespread in the cooler parts of Australia and its leaves are used as feed the koala.

Occurrence

The rod- shaped Eucalyptus comes in about 300 to 500 km wide strip along the coasts of southeastern Australia, from southeastern Queensland through New South Wales prior to western Victoria. In addition, it is found in Tasmania and on the islands west of Adelaide. It is common in many parts of its range, growing in grassy, bright or dense forest on nutrient-rich loamy soil.

Taxonomy

The first description of Eucalyptus viminalis was made in 1806 by the French botanist Jacques Julien de Houtou Labillardiere in novae Hollandiae Plantarum Specimen, Volume 2, page 12 The type material has the label " in capite Van Diemen " on.
