description

Appearance and leaf

Eucalyptus tenella grows as a tree that can reach heights of up to 15 meters. The bark remains on the entire tree, is gray to red-brown and fibrous. There are no oil glands in the marrow of the young branches or in the bark.

In Eucalyptus tenella , heterophyllia is present. The leaves are always divided into a petiole and a leaf blade. On young specimens, the leaf blade is linear to narrow-lanceolate, hairy and shiny green. On medium-old specimens, the leaf blade is 2 to 6 cm long and 0.3 to 0.7 cm wide, also linear to narrow-lanceolate, straight, with entire margins and shiny green. The leaf stalks on adult specimens are 5 to 8 mm long and narrowly flattened or channel-shaped. The leaf blade on adult specimens is lanceolate with a length of 5 to 12 cm and a width of 0.9 to 1.7 cm, the top and bottom of the same color, matt green, curved sickle-shaped, tapers towards the base of the blade, has a pointed upper one End and can be relatively thin or relatively thick. The side nerves, which are barely visible, extend from the median nerve at medium intervals at an acute angle. The cotyledons ( cotyledons ) are kidney-shaped.

Inflorescence and flower

Lateral on a 3 to 6 mm long and in cross-section pedicled inflorescence stem stand together in a single inflorescence seven to eleven flowers. The flower stalks, if present, are angular with a length of up to 1 mm. The not 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 that remains in place until flowering ( anthesis ). The smooth calyptra is hemispherical or broadly conical, shorter or twice as long as the smooth flower cup (hypanthium) and just as wide as this. The flowers are white or creamy white.

fruit

The seated fruit is 5 to 6 mm long and 5 to 7 mm in diameter spherical or hemispherical and four-faced. The disc is flat, the fruit compartments are level with the rim or protrude.

Occurrence

The natural range of Eucalyptus tenella is the Great Dividing Range in the east of New South Wales , west of Sydney , as well as the middle coast section of New South Wales, south of Sydney and Wollongong .

Eucalyptus tenella often thrives locally in dry, sparse hardwood forests on low-nutrient, flat soils on elevations.

Taxonomy
