This small to medium sized, warm to cool growing species originates from eastern New Guinea to Bougainville Island and is found at elevations of 800-1200 meters on trees in montane rainforests or as a terrestrial on steep wet moss covered slopes. The plant has basally fusiform to apically swollen, yellow, 3 to 5 noded stems below the 2 to 4, dark green, persistent, leathery, spreading leaves and blooms from March till May and August and September on an erect or arching, short to 3" [to 7.5 cm], few flowered raceme with 3 to 8, waxy, fragrant flowers that arise from the apex of a cane and requires regular waterings and fertilizer through out the year.
It is a small sized, cool to warm growing species and should never be allowed to dry out, regular daily waterings are best and they can be mounted on tree fern or grown in pots with a porous well draining media.
Very similar to D eximium but this one differs in the lack of hairs on the exterior of the sepals.
