Found in Myanmar, Thailand, Vietnam, Sumatra, Borneo and southern Malaysia in lowland and foothills at elevations around 300 to 1250 meters as a medium sized, hot to cool, pendent growing epiphyte with slender, erect, soft-canes carrying deciduous, lanceolate, acute, shortly petiolate leaves held in the upper half of the cane that blooms in the spring on a 1.2" [3 cm] long, 4 to 6 flowered inflorescence arising all along the apical 2/3's, of a mature cane in clusters at the nodes and carrying waxy flowers
Similar to D bifurcatum, D adunctum and D hercoglossum but this one differs in the much more open lip
