derwentiana is one of several species of Acacia with narrow,
pointed phyllodes. It is very similar to A. riceana, except
that the phyllodes are more elongate and are not clustered.
It is quite common along the banks of the Derwent River and its
tributaries (including the Tyenna and Broad Rivers), as well as the
tributaries of the Prosser and Carlton north and east of Hobart.
