Under trees in humid montane forest on laterite of gneiss, transition to lichen-rich forest.Because of its habit and the general appearance of its flowers, this species recalls D. latigaleata. It can be readily distinguished, however, by its ciliate petals and by the terminal appendage of its lip in which the midlobe is relatively short and covered by a short papillate pubescence while in D. latigaleata that lobe is legthened into a linear glabrous extension which is slightly dilated at the tip. The lip appendage also resembles that of some forms of D. oppositifolia, but the flower is glabrous, with the lateral sepals more extensively connate and contracted at the narrow base.
