Eucalyptus obliqua L’Hér.<br />
representative specimens found in the <strong>Quinta</strong><br />
Wi<strong>de</strong>spread in the property grounds, with its most<br />
striking example me<strong>as</strong>uring almost 45 metres,<br />
with a BHP of 5 metres.<br />
This is one of the most wi<strong>de</strong>ly distributed<br />
eucalyptus species in Australia, and can be found<br />
in New South Wales, Victoria, Southern Australia<br />
and T<strong>as</strong>mania. It is a large-sized tree, whose<br />
largest specimens may reach heights<br />
of 90 metres.<br />
With its reddish-brown bark, extremely fibrous<br />
and compactly intertwined in some sections, this<br />
eucalyptus owes its name to its leaves’ b<strong>as</strong>e. In<br />
fact, adult leaves have a clearly oblique shape,<br />
slightly undulated and alternate. Juvenile leaves<br />
have almost no peduncle and their arrangement<br />
is opposite in two to seven no<strong>de</strong>s.<br />
Flowering occurs between June and August in<br />
umbel-like cymes containing from 11 to 15 units<br />
and cover the tree. The fruit, supported by a very<br />
short peduncle, me<strong>as</strong>ure around one centimetre.<br />
This eucalyptus’ wood is heavy and is used in civil<br />
construction, structures and exterior and interior<br />
carpentry works <strong>as</strong> well <strong>as</strong> in floorings.<br />
It w<strong>as</strong> the first eucalyptus species to be <strong>de</strong>scribed,<br />
in 1788, by the French botanist, L’Héritier.
