divaricate arms; stigma cushion-like, 3-lobed; ovary slender 

 cylindrical. 



Described from several living and dried specimens. Colour of 

 the sepals and lip pure white, petals white with light purple 

 stripes, or sometimes entirely purple. In the dried state the 

 flowers of this species are puzzlinglylike those of D. tripetaloides, 

 and the two species are often confused in herbaria. Nevertheless 

 it is quite distinct, and may usually be distinguished by the 

 character of the remote leaves, which in the other species are 

 crowded at the base of the stem. Besides this the side sepals 

 are smaller in proportion to the galea, and, as noted, the petals 

 and lip are differently shaped, the former more erect and half- 

 exserted. The spur is somewhat variable in both, in D. tripeta- 

 hides it is usually thicker and blunter ; but forms of the latter 

 occur in which it is more slender, and then the flower more 

 resembles externally that of the present species.
