Previously included in Eucalyptus cypellocarpa or E. alaticaulis, and closely resembles E. litoralis. Generally distinguished from these species by the smaller fruits and relatively broad, blue-green juvenile leaves. It can be further distinguished from E. cypellocarpa by its smaller habit and slightly more persistent bark, and seedling stems that are distinctly winged (also see note under E. litoralis).
