GipP, Glep, HNF, NIS. Also WA, Tas. (Bass Strait Islands). Rare and threatened with extinction. In Victoria confined to woodland and scrub on limestone in the south-west.

Distinguished from the other native species by the cypsela shape and texture and the relatively short beak. The type description of T. cygnorum gives an cypsela length of 7 mm, but no material observed had cypselas this long.
