Plants slender, 70-170 mm tall; basal sheaths usually 2, hyaline, apices often green; leaves erect, subimbricate, linear, reaching the inflorescence, usually up to 60 mm long, grading into the floral bracts. Inflorescences dense, 20-50 mm long, scape, ovary and bracts beetroot-red; bracts as tall as the flowers. Flowers white, galea with a red-mauve dot apically, petals dark-blotched apically, basal '/3 of lip white, remainder lime. Median sepal obtuse with a fleshy apiculus, galea 3-4 x 2.5 x c. 1 mm deep, front margin incurved; spur horizontal from galea base, conical in dorsal view, apex decurved, 1-2 mm long, dorsal groove extending up the galea; lateral sepals patent, oblong, rounded, shallowly navicular, c. 4 mm long, apiculi massive, fleshy. Petals erect, partially included in galea, suboblong, emarginate, c. 2.5 mm long, apex reflexed, an obscure basal anticous lobe somewhat obscuring the stigma. Lip lorate, acute, 3-4 mm long, apex fleshy, surface tubercu-late. Anther cells pendent; stigma horizontal, shortly sessile, margins much taller than and curved over the receptive surface; lateral rostellum lobes smaller than the massive, fleshy central lobe.
