Description
Appearance and leaf
Eucalyptus tenella grows as a tree reaching heights of growth of up to 15 meters. The bark remains on the entire tree is gray to red-brown and fibrous. Neither in the marrow of the young branches still in the bark, there are oil glands.
In Eucalyptus tenella is available Heterophyllie. The leaves are always divided into petiole and leaf blade. In young specimens the leaf blade is linear to narrow - lanceolate, hairy and shiny green. At middle-aged specimens, the leaf blade is at a length of 2 to 6 cm and a width of 0.3 to 0.7 cm also linear to narrow - lanceolate, straight, entire and shiny green. The petioles of adult specimens are 5-8 mm long and narrow flattened or channel-shaped. The leaf blade is lanceolate in adult specimens with a length of 5 to 12 cm and a width of 0.9 to 1.7 cm at the top and bottom the same color dull green, curved like a sickle, tapering to the Spreitenbasis, has a pointed top end and can be relatively thin or relatively thick. The barely visible lateral nerves go from average distances at an acute angle from the midrib. The cotyledons ( cotyledons ) are kidney-shaped.
Inflorescence and flower
Page Constantly on a 3 to 6 mm long, terete in cross section inflorescence stem stand together seven to eleven flowers in a simple inflorescence. The flower stalks are, if any, with a length of up to 1 mm square. The non- blue-green floured or frosted flower buds are obovate or spindle-shaped with a length of 3 to 4 mm and a diameter of 1.5 to 2.5 mm. The sepals form a calyptra, which remains available until flowering ( anthesis ). The smooth calyptra is hemispherical or broadly conical, shorter or twice as long as the smooth flower cup ( hypanthium ) and as wide as this one. The flowers are white or off- white.
Fruit
The seated spherical fruit is at a length of 5 to 6 mm and a diameter of 5 to 7 mm or hemispherical and vierfächrig. The disc is flat, the fruit trays are at the height of the edge or stand out.
Occurrence
The natural range of Eucalyptus tenella is the Great Dividing Range to the east of New South Wales, west of Sydney, and the middle part of the coast of New South Wales, south of Sydney and Wollongong.
Eucalyptus tenella thrives locally frequent in dry, bright sclerophyllous forest on nutrient-poor, shallow soils on surveys.
