Commonwealth status: Extinct
Gazetted date: 21 Oct 2005
Profile last updated: 18 Nov 2019


Diuris bracteata is a terrestrial ‘donkey’ orchid with yellow flowers with blackish markings. The petals of the flowers (above the centre of the flower) are widely spaced and look somewhat like donkey ears. The lateral sepals (below the centre of the flower) are 9 mm long and 1.5 mm wide and turn abruptly downward and are crossed over. Flowers have been recorded from August to September.


For over 100 years Diuris bracteata was known only from the original collection made near Gladesville in northern Sydney.

In recent years plants of Diuris platichila from Duffy's Forest, Mount White and Kulnura were misidentified as Diuris bracteata (Peter Weston May 2013). 

The complete absence of records for most of the 20th Century resulted in this species being listed as 'presumed extinct' on Part 4 of Schedule 1 of the Biodiversity Conservation Act.
