Plants deciduous herbs, acaulescent, robust, 5-8 cm high (including tubers), arising from more or less ovoid tubers 3-4.5 x 3-4 cm, with numerous rounded outgrowths extending into downward-growing roots; tubers of older plants often showing vegetative shoots. Leaves 15-20 per growth, with the fleshy, translucent, greenish-white base below ground-level, 1.5-2 cm long and 3-4 mm broad, surrounded by a number of erect, fine, linear leaf-sheaths clasping the base, the outer half to two-thirds arranged in an almost flat, horizontal rosette, linear, acuminate-acute, margins slightly crenate, upper surface concave and with 3 prominent, longitudinal white veins and a network of ill-defined, fine, light greenish-white, horizontal and longitudinal veins, undersurface with a low keel, light grey-green, with a powdery white bloom and numerous parallel, longitudinal veins, 3-4 cm long, 4-6 mm broad and 2-3 mm thick. Inflorescence erect, 1-4 (one plant over a period of six weeks produced 18); peduncle 12-19 cm long and 2-3 mm in diameter; raceme diffuse to dense, 9-12 cm long and 2.5-3 cm thick; flowers 25-45, spreading, facing upwards; bracts narrowly triangular, membranous, 1.5 mm long, pedicels 8-12 mm long and 0.6-1 mm thick; tepals light greenish-yellow with a fine green central vein, those of outer whorl narrowly obovate, tightly reflexed, clasping pedicels, 5.5 x 1.2 mm, those of inner whorl narrowly obovate, reflexed at 45°, 5 x 2.5 mm. Filaments stout, bearded, dimorphic, 6 mm long, spreading at about 30° to 40°, outer and inner filaments with a single cushion of hairs angled towards the anthers; hairs clavate with elliptic apex, 2 mm long; anthers oblong, 0.5 mm long; flowers very strongly sweetly-scented. Ovary globose, green, 1 mm in diameter, style and stigma 6 mm long. Capsule spherical, 7 mm in diameter; seeds ca. 6-8 per capsule, large, broadly elliptic, angled, deeply and unevenly reticulate, finely granulate, shiny black, 3 x 4 mm.
