More small tips on Eucalyptus Identification

We have previously seen in EUCALYPTOLOGICS how bark features alone can be misleading for accurate Eucalyptus species identification, showing examples of different bark types for the same eucalypt species and of similar bark types for different eucalypt species. Today we will see how in some cases just a small sample of flower buds can yield an accurate identification.

Eucalyptus species identification for this tree as E. gomphocephala makes sense then both in a botanical and an historical sense. No doubt, Eucalyptology is an interdisciplinary science.
