Appearance and leaf
Eucalyptus baueriana grows as a tree that can reach heights of up to 20 meters. The bark remains on the entire trunk and the larger branches, is gray with white spots and fibrous and lumpy. At the top of the tree it is smooth, gray and peeled in short ribbons. The smaller branches have a green bark. There are no oil glands in the marrow of the young branches or in the bark.
In eucalyptus baueriana is Heterophyllie ago. The leaves are always divided into a petiole and a leaf blade. The petiole is narrowly flattened or channel-shaped with a length of 15 to 25 mm. The leaf blade on young specimens is circular and dull green. On middle-aged specimens, the leaf blade is about 10 cm long and about 7.5 cm wide, also circular, straight, with entire margins and dull green. The leaf blades of the same color on the upper and lower sides of the adult specimens are lanceolate or ovate, 6 to 9 cm long and 2.5 to 5.0 cm wide, relatively thin, straight, tapering towards the base of the blade or are rounded towards the stem and have a round or notched upper end. The raised lateral nerves extend from the median nerve at an acute angle at large distances. The cotyledons ( cotyledons ) are reversed kidney-shaped.
Inflorescence and flower
At the end of an inflorescence stem with a length of 5 to 10 mm in cross section, there are approximately seven-flowered partial inflorescences in compound total inflorescences . The pedicel-round flower stalks are 2 to 4 mm long. The not blue-green floured or frosted flower buds are club-shaped to short spindle-shaped with a length of 4 to 6 mm and a diameter of 2 to 3 mm. The sepals form a calyptra that falls off early. The smooth calyptra is conical, shorter than or as long as the smooth flower cup (hypanthium) and narrower than this. The flowers are white or creamy white. The outer stamens are sterile.
fruit
The stalked fruit is 5 to 7 mm long and 4 to 6 mm in diameter, conical and three to four-fold. The disc is indented, the fruit compartments are included.

The natural range of Eucalyptus baueriana are the middle and southern sections of the coast and the northern table country of New South Wales as well as in Victoria the estuary of the Snowy River and the area around Melbourne .
Eucalyptus baueriana often grows locally in light gallery forest on alluvial soils along watercourses.
