From a recent post at Tim Entwisle's Talking Plants blog,
about the Red Ironbark trees of central Victoria :
Bendigo, Castlemaine, Chiltern...
Red Ironbark wood is a 'handsome Australian hardwood', with excellent durability and strength - hence its use in wharves, bridges, railway sleepers and mining - as well as some beauty in crafted furniture and flooring. The species name, sideroxylon, translates as 'wood like iron'.
The Red Ironbark grown in streets and parks is the widespread Eucalyptus sideroxylon subspecies sideroxylon.

There is an indeterminate number of ranks.
The ICN explicitly mentions:[5]
