Found in Borneo in lower montane forests, low mossy scrub forests and in mossy hummocks at elevations around 1200 to 2550 meters as a miniature sized, cool to cold growing epiphyte or terrestrial or occasional lithophyte with a branching rhizome giving rise to close set to .8" [2 cm] apart, narrowly cylindrical to narrowly fusiform pseudobulbs carrying a single, erect, linear-ligulate to narrowly elliptic, obuse, mucronate, sometimes constricted below the apex, coriaceous, dark green almost metallic sometimes rather yellowish, 5 to 6 nerved, narrowing below into the sulcate petiolate base leaf that blooms in the fall on an erect, peduncle 2 to 4.4" [5 to 11 cm] long, rachis quadrangular, 6 to 10.4" [15 to 26 cm] long, subdense, many flowered inflorescence with a solitary, ovate-elliptic, acute bract and ovate, subacute floral bracts and carrying 2 ranked, sweetly scented, greenish yellow, pale lemon to pale green flowers.

A distinct species probably most clsosely allied to D subintegrum but with, among other things, much narrower leaves, and a broader labellum. Ames commented that the apical hood of the column is very variable, that of the type being three lobed, three toothed or almost entire.
