Allied to the preceding D. subacaule, but with narrower paired leaves and larger 
flowers, with a larger acute point to the lip. The flowers appear to have had reddish 
sepals, pale petals, and a reddish-orange lip.

This very curious little species, of which there is only one specimen, differs from the 
others in possessing a very short pseudobulb, from the apex of which rises a single leaf, 
which is articulated to a channelled petiole or sheath, which is longer than the raceme. 
The raceme bears a number of ovate bracts, and a pair of flowers of an orange colour— 
in other respects resembling those of other species of this section ; the winged petiole is 
also peculiar.

Allied to the preceding, but distinguished by the thicker dilated cast the 
yellow-green flowers with narrow sepals, and the hairy ovary.
