"Tree to 35 m tall. Forming a lignotuber. Ironbark throughout, hard or soft, sometimes flaky, grey, black, grey-brown; oil glands sometimes present in pith of branchlets. " (Euclid, 4th Ed.)

Distinguished from Eucalyptus fibrosa subsp. nubila which has glaucous buds and fruit, and also blue-green to grey-green or glaucous leaves. There are many ironbark species which can be confused with Eucalyptus fibrosa subsp. fibrosa however its often fibrous, softer bark can be helpful. If intending to work with the species a study of these and many other similar ironbarks should be made from Euclid, 4th Ed. or from Field Guide to Eucalypts. Vol. 3. 2nd edn.

For the seed collector this species can be problematic due to its height in some settings and far more amenable in others. It produces seed in reasonable quantities after good rainfall. In many instances and like many other ironbarks the ripening period is from late Summer onwards.
