Telopea truncata (Labill.) R.Br. Tasmanian waratah. In 1792–3, French botanist Jacques Labillardière collected specimens of this endemic plant which he formally described as Embothrium truncatum in his 1805 work Novae Hollandiae Plantarum Specimen. Robert Brown proposed placing the species in a new genus, Telopea, in a talk he gave in 1809, publishing the new name Telopea truncata in 1810.

Telopea truncata is endemic to lutruwita/Tasmania where it is found on moist acidic soils at altitudes of 600 to 1200m. as a component of alpine eucalypt forest, rainforest and scrub communities. Genetic analysis has revealed that the Tasmanian waratah is the most distinctive of the five waratah species.
