Tribonanthes brachypetala (common name Nodding tiurndin) is a species of the genus Tribonanthes in the bloodwort family, Haemodoraceae native to south western Western Australia.
It was first described by John Lindley in 1840.[1] It is a tuberous perennial herb growing from 0.2 to 0.4 m high, in swamps and areas which are seasonally wet.[2] It flowers from July to August.
The species epithet derives from the Greek brachys (short) and petalon (leaf, but here referring to petals) and describes the plant as having short petals.
