Morphology General Habit

Terrestrial herb.

Morphology General Rhizoids

Rhizoids and stolons capillary, numerous from the base of the scape.

Morphology Leaves

Leaves usually present at anthesis, scattered on the stolons, orbicular, peltate, long-petiolate; lamina fleshy, mucilaginous, 1–5 mm. in diameter; petiole 2–10 mm. long.

Morphology General Traps

Traps numerous, globose, stalked, 0.5–0.8 mm. long; mouth terminal; upper lip projecting; lower lip scarcely projecting, both provided with radiating rows of glandular hairs.

Morphology Reproductive morphology Inflorescences

Inflorescence erect, 2–35 cm. high; scape filiform, straight, ± setulose, papillose or rarely entirely glabrous; flowers 1–6(–10), distant; scales few, similar to the bracts; bracts basisolute, shortly produced below the point of insertion, ovate, apex acute, base truncate, ± 1 mm. long, setulose; bracteoles similar to the bracts but narrower; pedicels erect, 0.5–2 mm. long.

Morphology Reproductive morphology Flowers Calyx

Calyx-lobes subequal, broadly ovate, usually setulose; upper lobe ovate, 1.5–3 mm. long, apex acute; lower lobe ovate or orbicular, apex bidentate.

Morphology Reproductive morphology Flowers Corolla

Corolla white or pale lilac, 2–16 mm. long; upper lip 1.5–2 times as long as the upper calyx-lobe, narrowly oblong, apex rounded, truncate or ± emarginate; lower lip orbicular, entire; palate much raised, double-crested, the crests usually transversely tuberculate; spur usually conical-subulate, up to 4 times as long as the lower lip but very variable in length and sometimes much reduced.

Filaments filiform; anther-thecae subdistinct.

Morphology Reproductive morphology Flowers Gynoecium Pistil

Ovary ovoid; style short but usually distinct; stigma lower lip semi-orbicular, upper much smaller, deltoid.

Morphology Reproductive morphology Fruits

Capsule globose dehiscing by a longitudinal abaxial slit with thickened margins.
