"Tree to 10 m tall. Forming a lignotuber." (Euclid, 4th Ed.) Eucalyptus coolabah has rough bark over much or all of the trunk and smooth bark on the upper trunk and branches. The fruit exhibit strongly exserted valves.

Eucalytpus coolabah inhabits heavy-soiled floodplains and streambanks. It flowers in November and December and if fruit sets it will often ripen in March and April. Although a box tree with small fruit, its seed is collected in some volumes occasionally. The tree is quite accessible inland. Its habit is often straggly and its height relatively low on average so that fruit-bearing branches can be approached with some ease.

E.coolabah can be mistaken for other box species in a number of areas so if intending to work with the tree then the references below should be sort out to help avoid confusion. The tree has rough bark over much or all of the trunk and smooth bark on the upper trunk and branches. The fruit exhibit strongly exserted valves.
