This is D. punctata of the Flora Australiensis, and D. lilacina 

 of Baron von Mueller. A variety D. longissima is recorded in 

 the Flora as having been collected at Mudgee. It is the latest 

 Diuris to flower, lasting from the middle of September well on 

 into December. There is a considerable amount of difference 

 between the hill and the lowland forms.
