    Traps
    Traps scattered on the stolons and leaves, globose, shortly stalked, glandular, 0.6–1.5 mm. long; mouth basal; upper lip with 2 simple subulate appendages, lower lip with a single laterally compressed appendage.
    Inflorescences
    Inflorescence erect or twining, 3–35 cm. high; scape filiform, glabrous; flowers 1–8, distant; scales few, similar to the bracts; bracts basifixed, ovate-deltoid, 1.5–2 mm. long, up to 5-nerved; bracteoles linear, shorter than the bract; pedicels erect, narrowly winged, as long as or longer than the fruiting calyx.
    Calyx
    Calyx-lobes ovate, up to 5 mm. long at anthesis and 10 mm. long in fruit, ± unequal, upper usually larger, acute, obtuse or subacute, lower truncate or shortly bidentate.
    Corolla
    Corolla yellow, 8–20 mm. long; upper lip ± twice as long as the upper calyx-lobe, narrowly oblong to broadly spathulate, apex rounded, truncate or ± emarginate; lower lip ± orbicular, apex entire, bifid or obscurely 4-crenate; palate conspicuously raised, usually prominently longitudinally 4-ridged; spur subulate, acute, ± as long as the lower lip.
    Stamens
    Filaments linear, curved; anther-thecae subdistinct.
    Pistil
    Ovary ovoid, dorsiventrally compressed; style short; stigma lower lip rounded, upper lip smaller.
    Fruits
    Capsule ovoid, up to 5 mm. long, dehiscing by a longitudinal abaxial slit with thickened margins.
