Plants 15-25 cm tall, with a slender, creeping rhizome. Stem erect, pubescent and glandular hairy, with several sheaths at base and 2 or rarely 3 leaves above. Leaves subopposite or occasionally alternate, at or above middle of plant; blade often turning black or blackish when dried, elliptic, ovate or ovate-lanceolate, 5-12 cm long, 2.5-4.5 cm wide, abaxial veins sparsely pubescent or subglabrous, apex acute or acuminate. Inflorescence terminal, with 1 flower; peduncle densely pubescent and glandular hairy; floral bracts foliaceous, ovate-lanceolate, usually 1.5-3 cm, minutely ciliate, apex acute or acuminate; pedicel and ovary 1-1.5 cm, with glandular hairs. Flower white with purplish red or brownish red markings. Dorsal sepal ovate-elliptic or broadly ovate-elliptic, 1.5-2.2 cm long, 1.2-1.6 cm wide, often sparsely puberulent toward abaxial base, apex acute or shortly acuminate; synsepal narrowly elliptic, 1.2-1.8 cm long, 0.5-0.6 cm wide, apex shallowly 2-lobed. Petals often subspatulate or pandurate, 1.3-1.8 cm long, 0.5-0.7 cm wide, hairy toward adaxial base, apex often slightly dilated and rounded; lip deeply pouched, pitcher-shaped, ca. 1.5 cm long, 1.5 cm wide, lacking an incurved apical margin, with a broad mouth, inner bottom hairy. Staminode ovate-elliptic, 4-5 mm long, 2.5-3 mm wide, abaxially broadly keeled, adaxially minutely longitudinally ridged, apex emarginate or subtruncate. Capsule pendent, nearly narrowly ellipsoid, ca. 2.5 cm long, 8-10 mm wide, puberulent.
