Terrestrial herb. Rhizoids and stolons capillary, numerous at the base of the peduncle. Leaves scattered on the stolons, narrowly obovate-spathulate, 10–30 × c. 1 mm., 1-nerved. Traps numerous on the stolons and leaves, ovoid, 0.3–0.8 mm. long, stalked; mouth terminal, with a dorsal fringe of c. 5 glandular hairs and ventral radiating rows of more or less sessile glands. Inflorescence erect, simple, 5–25 cm. high; peduncle filiform, straight, glabrous above, setulose at the base; inflorescence axis straight; flowers 1–5, usually distant; scales numerous, similar to the bracts; bracts basifxed, lanceolate with apex acute, 1.2–1.5 mm. long; bracteoles similar to the bracts but slightly longer; pedicels up to 1 mm. long. Calyx lobes subequal, broadly ovate, 2.5–3.5 mm. long, minutely papillose or smooth, flat, the margin deeply divided into 7–11 subulate teeth. Corolla 7–15 mm. long, mauve or violet with a yellow spot on the palate; superior lip broadly ovate, with apex retuse, 2–25 times as long as the upper calyx lobe; inferior lip reniform with apex distinctly 3-crenate; palate raised, 2–4 gibbous; spur subulate, acute, about 1.5 times as long as the inferior lip. Filaments filiform; anther thecae sub-distinct. Ovary globose; style very short; stigma inferior lip semi-circular, superior much smaller, deltoid. Capsule globose, 1.5–2 mm. long, dehiscing by dorsal and ventral lanceolate pores. Seeds numerous, ovoid, somewhat angular, c. 0.2 mm. long; testa smooth, the cells indistinct, more or less isodiametric.
