The nearest allies of this species are D. Ruttenii J. J. S. from Ceram 

 and D. pachystele Schltr. and D. informe J. j. S. from New Guinea. They 

 resemble each other closely but are specifically distinct. In the two Papuan 

 species the side lobes of the lip are subobsolete, whereas they are trian- 

 gular in D. Laursnsii and quadrangular in D. Ruttenii. The column foot 

 is much thickened at the apex in D. Laurensii. In ail species the lip is 

 very fleshy, so that it is very difficult or impossible to spread it out.
