Acacia
is one of the largest, most obvious and ecologically significant
genera in Tasmania, with 21 native and seven introduced
species. All are trees or shrubs. Ecologically the species range
across most habitats excluding aquatic, saltmarsh and alpine areas.
The flowers are small, with the stamens being the most
conspicuous parts. The flowers are arranged in either dense heads or
dense spikes. The leaves are either replaced by phyllodes (most
species), or are bipinnate (A. mearnsii, A. dealbata, A.
decurrens and A. terminalis). Many phyllodinous species
have bipinnate juvenile foliage.
