A terrestrial herb ± 3 dm. high.. Tubers not seen.. Stem erect, slender, with a single basal foliage leaf and a number of very small sheaths scattered along its length, ± densely pubescent.. Basal leaf adpressed to the soil, reniform-orbicular, rounded at the apex, cordate at the base, 2–3 cm. long and 3.5-4 cm. broad, glabrous with ciliate margins; sheaths on stem lanceolate, acuminate, 0.5–1.5 cm. long, ± densely pubescent.. Inflorescence 4–7 cm. long, 3 cm. in diameter, loosely to rather densely 8–11-flowered; rhachis pubescent.. Bracts similar to the stem-sheaths, 5–12 mm. long.. Flowers suberect, not resupinate, facing outwards, no colour recorded; ovary with pedicel ±1.5 cm. long, pubescent.. Intermediate sepal at right angles to ovary or somewhat reflexed, convex, elliptical-ovate, rounded, ± 7 mm. long and 4 mm. broad; laterals scarcely spreading, obliquely lanceolate-elliptical, obtuse, a little longer than the intermediate sepal but only ± 3 mm. broad; all sepals sparsely hairy outside, the margins ciliolate.. Petals obliquely wedge-shaped, 2-lobed in the upper third, ± 8 mm. long; lobe nearest the intermediate sepal oblong-elliptical, rounded, ± 3 mm. long and 2 mm. broad, the lobe nearest the lip lanceolate-linear, subacute, ± 2 mm. long and 1 mm. broad, both lobes with papillose margins.. Lip 3-lobed in the apical half, ± 10 mm. long and broad between the ends of the side lobes, glabrous; basal undivided part ± 4 mm. long, somewhat widened upwards; middle lobe ± recurved, linear-ligulate, obtuse, 5–6 mm. long, just over 1 mm. broad; side lobes spreading forwards, ligulate, obtuse, about equalling the middle lobe but a little broader.. Spur hanging downwards, swollen in the apical third, ±1.5 cm. long.. Anther 2 mm. high, rounded, loculi partly reclinate, canals slightly curved, ± 1.5 mm. long.. Stigmas thick, ± curved downwards, club-shaped, just over 1 mm. long.. Rostellum triangular, acute, 0.5–1 mm. long.
