Plant ca. 150 mm tall. Leaves all cauline, 4, linear-lanceolate, tapering to an acute apex, the upper overtopping the base of the inflorescence, 65 x 10 mm, the lower leaves somewhat bigger. Inflorescence spike-like, 60 x 25 mm, with 18-20 flowers; bracts purplish-green, linear-lanceolate, acute, lowermost grading into the leaves and much overtopping the flowers, uppermost as tall as the flowers; ovary and pedicel up to 15 mm long. Flowers resupinated, white with purple mottling but spur and spur entrance green and stigma white; lateral sepals spreading and more or less decurved and somewhat reflexed, narrowly oblong, apically rounded, shallowly concave or navicular towards the apex, 9 x 4.3 mm, apiculus pointed, 0.5 mm long; dorsal sepal shallowly galeate, oblong to elliptical and apically obtuse in front view, 9 x 5 mm, in side view shortly pedicellate and set back from the rostellum, spur straight, 2.5 mm long, borne near the base of the galea, laterally compressed at entrance and apically somewhat flattened; petals reflexed parallel to the anther, basal anticous lobe more or less square, flanking the stigma, 2 x 2 mm, limb linear, acute, apex upcurved, whole 3.5 x 0.9 mm, subfleshy, attached to the rostellum with a slender lateral flange; lip pendent, three-lobed, lateral lobes more or less square, 1.5 x 1.3 mm, patent, central lobe linear, obtuse, 7.8 x 0.8 mm, subfleshy, the apical half more or less recurved. Rostellum flanked by linear auriculi, tall, erect, three-lobed; lateral lobes canaliculate, 1.5 mm tall, apically with two separate, globular viscidia; central lobe drop-shaped, nestling between the lateral lobes. Anther reflexed, held between the petal limbs, 1.5 mm long, ovate to globose. Stigma erect, column-like, ca. 1 mm tall, with three equal-sized pulvini.
