Petals bilobed, posterior lobe linear-subfalcate, about as long as the median sepal with which it is coherent along the inner margin, obtuse, anterior lobe longer than the posterior lobe, from a linear base divided into more or less divergent filiform segments. Lip 3-lobed, spurred; lateral lobes from a linear base divided into filiform segments similar to those of the anterior lobe of the petals; mid-lobe narrowly linear, 0.8 cm long, subacute; spur pendulous, cylindric, shorter than the ovary, a little widened in apical third.
