Flower buds are an elongated cone shape and measure up to 12mm in length (3). Hence the term gum tree. Koalas eat the leaves of about 20 of the 700 species of eucalyptus trees that are found in Australia. In tall open forests it develops a straight trunk devoid of major branches up to the height of the relatively open crown (Picture 1). It is different shades of grey in colour and sheds in irregular sized plates, a short stocking of rough bark can be found at the base of the tree (2). It inhabits open Eucalypt forests and woodlands at lower elevations. It features mostly 3 valves with pointed tips reaching rim level or slightly above (4).

Shrub varieties of eucalyptus, also called mallee, are multistemmed and look like shrubs rather than trees. The Red Mahogany Eucalyptus resinifera is a tall tree reaching heights of more than 40m and occurs mainly in tall open forests (Picture 1). The eucalyptus tree is the mainstay of Australia’s forests; over 700 species of eucalyptus exist in this large continent. Fruit greatly varies in size and shape, making it useful in the identification of different species. Weathered outer bark is grey in colour, fresh underlying bark is light brown (2). Note: This species is a primary koala food source. Blackbutt Tree Eucalyptus pilularis The common name refers to the strongly lemon-scented leaves of this tree, which are of great help when identifying this species, as it is of similar appearance to the Spotted Gum E. maculata. It is very similar in appearance to a number of other Stringybarks, such as the White Stringybark (E. globoidea) Tindale's Stringybark (E.tindaliae) (Picture 1). They typically grow no more than 10 feet tall in the high mountains and coastal cliffs in Australia, but given more hospitable conditions, varieties grow up to 25 feet tall, such as sand mallee (Eucalyptus eremophila) and red-flowered mallee (Eucalyptus erythronema).

A broad disc and 4 slightly exerted valve tips are typical (3). Whereas within wet tall forests it has to compete for light and may reach a height of more than 30m (1). Mid vein is raised on both surfaces and numerous straight lateral veins are obvious. The shape of the fruit is varied from cup-shaped (cupular) to more upside down cone-shaped (obconical).
