Eucalyptus sclerophylla, known as the Scribbly Gum, is a tree native to eastern Australia. Very similar to the related Scribbly Gum (E. haemastoma), a better known tree. The best way of distinguishing the species is the smaller hemispherical to pear shaped gumnuts of Eucalyptus sclerophylla, being 0.6 cm by 0.6 cm in size. Flower buds are also smaller. sclerophylla literally means hard leaf. Both species have hard leaves, but Eucalyptus sclerophylla's leaves are particularly hard edged.
