Taxonomic notes: The leaves closely resemble those of the W.Aust. wheatbelt endemic T. kochii which has the same number of stamens and ovules but completely different hypanthium and fruit. The relationship of these two species forms a remarkable parallel with that between T. biseriata and T. urceolaris.
