Similar to the Philippine D graciiscapum but D alatum has large elliptical stelida which superficially resemble side lobes of the lip. D corrugatum differs in the wider, fimbriate lip. D pterogyne is similar but D alatum differs in the larger flowers with a lip usually broadest at the middle and a longer column with narrower stelida.
