Eucalyptus is the genus
of trees and some shrubs of the myrtle family. This genus, which includes over
800 species, forms the preponderant vegetation and most valuable timber trees
of western Australian forests. Eucalyptus trees are characterized by leathery,
whitish leaves that hang vertically, their edges facing the sun, and their
ragged bark and peculiar aroma. Some trees in the genus are among the tallest
trees known. One specimen of mountain ash with a height of at least 97 m (at
least 318 ft) was found near Melbourne, Australia.
Many species
are known as gum trees because of their resinous exudations. Among these are
the blue gum and the cider gum, the lumber of which is widely used. Other
species are known as stringybarks because of their fibrous inner bark. The
peppermint trees, black peppermint and Sydney peppermint, are also included in
this group. The ironbarks have hard gray bark and yield good timber. Botany Bay
kino, a dark red, odorless gum employed as an astringent and a hemostatic drug
and for tanning and dyeing, is derived from the ironbarks. The bloodwoods have
reddish wood and also yield Botany Bay kino. Dragon's blood, tannin, oils,
dyes, tars, and acids are yielded by other species of eucalyptus.
