    Habit
    Terrestrial herb.
    Rhizoids and Stolons
    Rhizoids and stolons capillary, few from the base of the peduncle.
    Leaves
    Leaves few, branch-opposed on the stolons, linear, 1-nerved, up to 10 ×1 mm.
    Traps
    Traps scattered on the stolons and leaves, globose, shortly stalked, glandular, 0.6–1.0 mm. long; mouth basal, with 2 dorsal simple subulate appendages, a single shorter truncate or shortly bifid ventral appendage.
    Inflorescences
    Inflorescence erect or twining, 3–35 cm. high; peduncle filiform, glabrous; flowers 1–8, distant, usually alternating with sterile bracts; scales few, similar to the bracts; bracts basifixed, broadly ovate-deltoid, acute or acuminate, nerveless, 1–1.5 mm. long; bracteoles linear-lanceolate, more or less 1 mm. long; pedicels spreading or erect, 1–3 times as long as the flowering calyx, narrowly winged.
    Calyx
    Calyx lobes broadly ovate, 2.5–3 mm. long at anthesis, up to 5 mm. long in fruit, deccurent, slightly unequal; upper longer, with apex acute or acuminate; lower with apex shortly 2–3-dentate.
    Corolla
    Corolla yellow, 5–15 mm. long; superior lip shorter than to about twice as long as the upper calyx lobe, oblong to circular, with apex more or less emarginate; inferior lip circular, with apex rounded, entire or 2–3-crenate; palate raised, usually 2–4 gibbous; spur subulate, acute, more or less curved.
    Stamens

    Fruits
    Capsule oblong-ovoid, dorsiventrally compressed, 2–2.5 mm. long, dehiscing by a longitudinal ventral slit with thickened margins.
