A nineteenth-century Victorian collection at MEL ('plains on the Avon') and 3 old collections from New South Wales seem to be intermediate between T. cygnorum and T. aristum. Since these collections are rather fragmentary, modern collections from these localities are needed to assess their significance. They may represent an undescribed section Antarctica species rather than intermediates between T. cygnorum and T. aristum.
