Herb, 2.5–3.5 cm. tall, the stem densely covered with short papilla-like hairs, arising from a round or ellipsoid tuber 0.6–1.4 cm. long, 4–7.5 mm. wide.. Leaf 1 (excluding 1–2 basal scale leaves), sessile, sheathing at the base, broadly ovate, 6–8 mm. long and wide, shortly acuminate, cordate above the sheath, densely papillate above and on margins.. Flowers solitary, yellow, yellow-brown or reddish, sometimes tinged purple; bract leaf-like, lanceolate, 7–9 mm. long, 3.5 mm. wide, subacute, papillate-ciliate on the margins.. Intermediate sepal linear-lanceolate, boat-shaped, 8 mm. long, 1.8 mm. wide, joined to the petals to form an elliptic inflexed open hood, the sepal itself forming a longitudinal sunken trough along the long axis; lateral sepals semicircular, 6 mm. long, 3.5 mm. wide, acute, free, bearing sacs 0.8 mm. long.. Petals oblong-linear, falcate, 8 mm. long, 2.8 mm. wide.. Lip with claw bent back on itself shortly above the point of adnation with the column then expanded into a minutely papillate triangular limb, 3.5 mm. long, 2 mm. wide, produced apically into a narrow tip.. Ovary hairy.
