The Manna gum (Eucalyptus viminalis) belongs to Myrtaceae (the Myrtle family). It is a tall evergreen tree that is distributed from New South Wales to Tasmania, Victoria, in the southwestern part of Australia. The height is usually about 18 to 24 m, but it can be 50 m or more. The bark is whitish and smooth, but at the bottom of the mature tree it is brown and peels off like a ribbon. The leaves are narrow lanceolate, turquoise, 8-20 cm long. From January to May, white flowers with prominent stamens bloom on the axils. Aboriginal people have used the sweet sap that oozes from small holes in the branches. It is also one of the "eucalyptus" that koalas like to eat.
