Taxonomic notes: This species is rather variable and is not always easily distinguishable from small-fruited specimens of T. tetragonioides. It sometimes has black fruits with large wings making it difficult to separate from the earlier described T. diptera with which it may even be conspecific. Some of the specimens identified as T. expansa by J. Black refer to this species.
