Diuris bracteata was a terrestrial 'donkey' orchid with yellow flowers with blackish markings. The petals of the flowers (above the centre of the flower) were widely spaced and looked somewhat like ears. The lateral sepals (below the centre of the flower) were 9 mm long and 1.5 mm wide, turned abruptly downward and crossed over (Jones 1993b; NSW OEH 2014e). Flowering was recorded in September (Fitzgerald 1888).

Diuris bracteata is known from a few sites in the Sydney Basin Bioregion, collected in 1998 (NSW DECCW 2005cp). The species is considered to have never been widely distributed (Clements 1989; NSW DECCW 2005co).

Prior to 2005, Diuris bracteata was listed as presumed extinct in NSW. Prior to the collection in 1998, the species was only known from the original collection near Gladesville, on the Parramatta River, NSW (Fitzgerald 1888).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
