description
Appearance and leaf
Eucalyptus ovata grows as a tree that can reach heights of up to 30 meters. The bark on the lower part of the trunk or on the entire tree is smooth, gray-black and short-fibered. At the top of the tree, it is smooth, white, pink, or yellow, and peels in long, wide ribbons. The bark of the branches is green. There are oil glands in the bark, but not in the marrow of the young branches.
In Eucalyptus ovata is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. The leaf blade on young specimens is elliptical, later ovate, and dull green. On middle-aged specimens, the leaf blade is about 19 cm long and about 8.5 cm wide, also elliptical and later ovate, straight, with entire margins and dull green. The petiole on adult specimens is narrowly flattened or channel-shaped with a length of 17 to 25 mm. The leaf blade on adult specimens is glossy green on the top and bottom and is 6 to 15 cm long and 1.5 to 5 cm wide, lanceolate or ovate, straight, relatively thick, tapers towards the base of the blade and has a blunt or rounded upper end. The raised lateral nerves branch off from the median nerve at medium intervals at an acute angle. The cotyledons ( cotyledons ) are upside-kidney-shaped.
Inflorescence and flower
On the side of an inflorescence stem up to 14 mm long and with a pedicel round cross-section, there are about seven flowers together in a single inflorescence . If available, the pedicels are up to 5 mm long and stalk-round. The not blue-green floured or frosted flower buds are egg-shaped or spindle-shaped with a length of 6 to 11 mm and a diameter of 4 to 6 mm. The sepals form a calyptra that falls off early. The smooth calyptra is conical or beak-shaped, once or twice as long as the smooth flower cup (hypanthium) and as wide as this. The flowers are white or creamy white.
fruit
The stalked fruit is conical or bell-shaped with a length and a diameter of 4 to 7 mm and three to four-faced. The disc is flat, the fruit compartments are level with the rim.
Occurrence
The natural distribution areas of Eucalyptus oleosa are in the southern coastline and in the southern table country of New South Wales south of Sydney , on the entire south coast of Victoria , in the southeast of South Australia around Adelaide and Mount Gambier and in Tasmania .
Eucalyptus oleosa often grows locally in sparse forests with sweet grasses and sour grass plants in low-lying and permanently moist locations.
Systematics

The type material has the inscription " In Terra Van Leuwin " link. The specific epithet ovata is derived from the Latin word ovus for egg and indicates the shape of the leaves.
