description

Trunk and bark
Sickle-shaped, simple leaves

Appearance and leaf

The rod-shaped eucalyptus grows as a tree that reaches heights of up to 30 meters, sometimes 50 meters. The bark is smooth on the whole tree or remains on the lower part of the trunk, is gray to gray-black and has short fibers. On the upper parts of the tree, the bark is smooth, white, yellow or gray and peels in long ribbons. The small branches are green. There are oil glands in the bark, but not in the marrow. The bark of the branches is green.

The rod-shaped eucalyptus has heterophyllia . The leaves on young specimens are opposite, lanceolate, entire, dull green. The opposite, dull green leaves on medium-old specimens have no petioles and are about 15 cm long and about 0.3 cm wide, lanceolate, straight, with entire margins. The leaf stalks on adult specimens are narrow-flattened or channel-shaped in cross section and 10 to 25 mm long. The single-colored, glossy green leaf blades on adult specimens are sickle-shaped, narrow-lanceolate to lanceolate, with a length of 8 to 20 cm and a width of 0.8 to 2.5 cm, with a tapering blade base and rounded or edged upper end. The raised lateral nerves branch off from the median nerve at medium distances at an acute or obtuse angle.

Inflorescence and flower

On the side on a narrow-flattened or angular, 4 to 8 mm long inflorescence stem, there are only about three flowers in a simple inflorescence . The outer stamens are sterile. The flowers are white or cream in color. The pedicel-round flower stalk can hardly be seen and is up to 3 mm long at the most. The not blue-green frosted or floured flower bud is egg-shaped with a length of 5 to 8 mm and a diameter of 3 to 5 mm. The sepals form an early sloping "calyptrata" or "operculum" . The smooth calyptra is conical or hemispherical and at least as long and wide as the smooth flower cup (hypanthium). The flowers are white or cream in color.

fruit

The stalked or sessile fruit is 4 to 8 mm long and 4 to 9 mm in diameter spherical, egg-shaped or cylindrical with three or four fruit compartments. The disc is raised and the fruit compartments protrude.

ecology

Eucalyptus viminalis is widespread in the cooler areas of Australia and its leaves are used as food for the koala .

Distribution area

Occurrence

The rod-shaped eucalyptus occurs in a strip about 300 to 500 km wide along the coasts of southeastern Australia, from southeastern Queensland via New South Wales to western Victoria . It can also be found in Tasmania and on the islands southwest of Adelaide . It is common in many regions of its range and grows in grassy, sparse or dense forests on nutrient-rich loam soils .
