Now, if this evidence for Eucalyptus identification is right, the matter is if those trees at Antibes would be a "pure species" or just "half of it". To work that out, further comparison of tree organs is important, and reporting as many as known "old rough barked Cider Gums" also is.
The 3 trees at Villa Thuret seem to have the top half and main branches covered by smooth whitish bark, and the lower half fibrous and brown, becoming very coarsely rough at the base, almost looking like an "ironbark". If they are relatives of the Cider Gum, or yet another example of Thuretian Eucalyptus hybrids, could be known by patient observation of similar trees... and by trying to grow some progeny (juvenile leaves would give good hints!)
Also, it may help getting to know when these trees were planted, by whom and where did seed come from
What is nearly sure is they are not E. vernicosa. And, very likely, the younger tree at Florama is not either. It may easily be an E. subcrenulata, or an intermediate form of this and E. vernicosa. Both species intergrade ("mix") in Tasmania, the same way that those in the E. gunnii complex also do (in Tasmania too!).
