In outline the labellum is orbicular as the lateral lobes envelop the 
middle one. The divisions are cuneate, rounded and radiate from the 
tube formed by the union of the column and the base of the lip. The 
column is fleshy and in front passes obliquely into a dentate crest on the 
disc of the lip on each side.

Nearly related to Dendrobium uncatum Lindl. which has much larger 
flowers, shorter leaves and a slightly different labellum. The three lines 
on the disc appear to terminate 1.5 mm from the apex of the labellum

with purple markings.
