Eucalyptus marginata
''Eucalyptus marginata'' is one of the most common species of ''Eucalyptus'' tree in the southwest of Western Australia. The tree and the wood are usually referred to by the Aboriginal name jarrah. Because of the similar appearance of worked jarrah timber to the Honduras mahogany, jarrah was once called Swan River mahogany after the river system that runs through Perth.
==Description==
The tree grows up to high with a trunk up to in diameter, and has rough, greyish-brown, vertically grooved, fibrous bark which sheds in long flat strips. The leaves are often curved, long and broad, shiny dark green above and paler below. The species' scientific name ''marginata'' refers to the light-coloured vein on the border around its leaves. The stalked flower buds appear in clusters of between 7 and 11; each bud has a narrow, conical bud cap long. The flowers are white, in diameter, and bloom in spring and early summer. The fruits are spherical to barrel-shaped, and long and broad.
The bark of this ''Eucalyptus'' is not shed in patches as it is with many others, but splits into fibrous strips. Jarrah trees are also unusual in that they have a lignotuber, a large underground swelling which stores carbohydrates and allows young trees to regenerate after a fire. Because they are deep-rooted, as much as , jarrah are drought resistant and able to draw water from great depths during dry periods.
