HSF, HNF, MonT, HFE, VAlp. Also Tas. In Victoria, known with certainty only from near Bidwell on the upper reaches of the Delegate River, and near Omeo on the Cobungra River and the Upper Livingstone Creek.
This species is readily characterized by the metallic sheen on the fruits. Victorian plants differ from those in Tasmania in having only the lowermost flowers in opposite pairs.
