riceana is one of several species of Acacia with narrow,
pointed phyllodes. It is common in wet forests, especially in
southern Tasmania, where it is a tall shrub or small tree. The
distinctive feature is the way that the phyllodes are clustered in
groups of 3-6 (although not in whorls as in A.
verticillata). It is closely related to A.
derwentiana, but differs in having broader phyllodes, which
are in clusters.
