This usually grows on lofty trees. It is not very common, 
rarely met with in flower, nor does it often flower in cultivation.

‘This species is very closely allied to D. Serra, Liudl., but is 
distinct in its broader leaves and stems, remarkably short foot 
of the column, and correspondingly short mentum, and 
especially in the very much broader mid-lobe of the lip, which 
in D. Serra, Lindl., is but little shorter than the basal portion.

This much resembles D. atropurpureum, Miq., but is a taller 
plant with shorter leaves. There are a number of bracts at the 
base of the peduncle, but they do not break up into fibrils as in 
D. atropurpureum, Mig. The flowers are larger, orange yellow, 
the petals tipped with red. The lip is pale red with a darker 
callus composed of two club-shaped caruncles meeting in @ 
V shape (that of D. atropurpureum, Miq., is semicircular). The 
tubercle under the lip is like that of D. atropurpureum. At the 
base of the lip are two very small lanceolate or tooth-like 
acute lateral lobes. The column is pale red with a darker spot 
at the base.
