In addition to flower colour, D. variegatum can be distinguished from D. roseum (which also has recurved perianth segments) by its labellum callus forking into 2 slender, divergent keels rather than into two tapering, convergent keels; the dense patch of tangled hairs at the apex of the labellum; the humped (gibbous) ovary with a warty surface (the ovaries of D. roseum can be either smooth or sparsely warty); and the long-acuminate rather than obtuse to shortly acuminate stem bracts.
