The bark remains on the lower 1 to 2 meters of the trunk, is pale brown and fibrous integrally. On the upper parts of the tree it is smooth, glossy gray, gray - brown or red and peels off in strips. The bark of young branches is green. Oil glands there is neither in the bark still in the marrow of the young branches.

In Eucalyptus oleosa is available Heterophyllie. In young specimens the leaves are linear, dull gray - green or green, spirally arranged and crowded. At middle-aged specimens the leaves seated at a length of about 8 cm and a width of about 0.8 cm are also linear, straight, entire, dull and gray - green or green. The on upper and lower sides of the same color glossy green leaves on adult specimens are divided into petiole and leaf blade. Your petiole is 8-18 mm long and narrow flattened or channel-shaped. Your leaf blade is narrow lanceolate or lanceolate with a length of 7 to 10 cm and a width of 0.8 to 1.5 cm, straight, relatively thick, tapering to the Spreitenbasis and has a pointed upper end. The barely visible lateral nerves go from average distances at an acute angle from the midrib. The cotyledons ( cotyledons ) are in two parts.

Inflorescence and flower

Constantly on a page with a length of 7 to 12 mm and a width of up to 3 mm in cross section, narrow flattened or angular inflorescence stem are in a simple inflorescence eleven to thirteen flowers together. The 1-5 mm long flower stems are terete. The non- blue-green floured or frosted flower buds are cylindrical or egg-shaped with a length of 5 to 8 mm and a diameter of 3 to 4 mm. The sepals form a calyptra, which drops early. Smooth Calyptra is hemispherical or conical, twice as long as the smooth flower cups ( Hypanthium ) and so wide that, or even as long as the flower cups and narrower than the latter. The | flowers are white, cream white. or yellow. The flowering period extends into Western Australia in November and December.
