Habitat? (Cuit, in Hort. J. G. Dammerboek, Buitenzorg). 

 Halmaheira? (Cuit, in Hort. Bog.). 



The nearest ally of this species is D. Strepskeros J. J. S. from the 

 island of Batjan. It differs from the latter in the smaller differently coloured 

 flowers, the petals being broader at the apex, the midlobe having a longer 

 claw and not being warty inside, the 3 inner keels being much more 

 conspicuous at their apex, the column not being appressed to the lip. 



It is a pretty species with long lasting and fragrant flowers. The habitat 

 Halmaheira is not wholly sure.
