Description:
A terrestrial herb 3-5.5 dm. high, glabrous except for the roots; tubers 1-2, ovoid, ellipsoid or cylindrical-ellipsoid, 2.5-4 cm. long, 1-2.5 cm. in diameter, densely tomentose; roots slender, flexuous, pubescent. Stem erect, slender or rather stout, terete, with 2 basal leaves and several distant sheaths. Two basal leaves subopposite, broadly ovate to reniform, adpressed to the ground, 3-7.5 cm. long, 3.5-11 cm. broad; sheathing leaves 3-6, lanceolate, subacute, 4-6-5 cm. long, 1-2 cm. broad. Inflorescence not very dense, 4-14 cm. long, 5-7 cm. in diameter, 3-12-flowered; bracts at first erect, later reflexed, lanceolate, acute, 2.5-4 cm. long. Flowers curved outwards, white; pedicel with ovary slightly curved or straight, 12-14 mm. long. Sepals projecting forwards or slightly decurved, united very shortly at the base to the petals and lip; intermediate sepal oblong-lanceolate or narrowly oblong-elliptical, obtuse, 1.7-2.3 cm. long, 3-6.5 mm. broad; laterals obliquely oblong-lanceolate or elliptical-oblong, obtuse, a little longer than the intermediate, 5-8 mm. broad. Petals oblong-oblanceolate, rounded at apex, equalling the intermediate sepal, 4.5-7.5 mm. broad; all tepals several-veined, intermediate sepal and petals with a low median keel on the outside in the lower half. Lip very convex or almost hooded, the apex curved back, 1.6-2.3 cm. long and nearly as broad when spread out, 2-spurred at the base; spurs slender, parallel to the ovary and stem, 2.2-3.5 cm. long, scarcely 2 mm. in diameter at the base. Column erect, ± 1 cm. high, the stalk ± two-thirds of the total height, rather stout; anther-loculi pendent below the rostellum, rather small, ellipsoid, viscidia ovate, 3 mm. long; stigma transversely semi-orbicular, distinctly 2-lobed, the apex emarginate, sometimes apiculate in the middle, 7.5-9 mm. broad but only 4.5 mm. high, rostellum projecting forwards, 3-lobed, the side lobes small, acute, ± incurved, the middle lobe much larger, ± bifid.
