Marri - also known as Redgum

Corymbia calophylla (formerly Eucalyptus calophylla )
Also known as Marri, Redgums grow in diverse areas such as the southwest to north of Geraldton, and east into the wheat belt. It is a medium to tall tree, up to 40m in height, and produces an amazing display of flowers and yields copious amounts of nectar and pollen. The nectar attracts lots of birds, insects and other fauna and is a favourite for planting in parks, roadside stops, and gardens. Generally used for wood chipping, the Redgum often has "Kino" or gum veins, which has restricted its use as a feature timber. Kino is a gummy substance produced by the tree in response to injuries, such as from insects, fungi or fire. Although all eucalypts produce Kino, some species produce more than others. Recently such markings have been viewed as features where as in the past they were seen as flaws.
