Characteristics

Very small to medium sized annual or perennial, terrestrial. Rhizoids few to many, capillary, simple, often densely glandular, a few cm long, 0.1-0.2 mm thick. Stolons few, capillary, much branched, up to 5 cm long, 0.2-0.4 mm thick. Leaves few, usually 1 at the peduncle base, others scattered on the stolons, petiolate, the lamina narrowly cuneate or obovate to reniform, 1-6 mm wide, several to many nerved; total length 0.2-7 cm. Traps numerous on the rhizoids, stolons and leaves, ovoid, stalked, 1-2 mm long, the mouth terminal with a rounded dorsal appendage and a similar but shorter ventral appendage, both with radiating, comb-like rows of stipitate glands. Inflorescence erect, solitary, simple or branched above, 2-80 cm long; peduncle terete, 0.5-2 mm thick, glabrous. Scales few to many, similar to the bracts. Bracts basifixed, ovate to ovate-deltoid, with apex acute, c. 1 mm long. Bracteoles similar to the bracts but narrower. Flowers (1-)2-8(-50 or more in branched inflorescences), distant to congested; pedicels terete, 1-3 mm long, erect in flower, spreading or reflexed in fruit. Calyx lobes ± equal or the upper broader and shorter than the lower, ovate, with apex obtuse to subacute, 2-5 mm long, always plicate along the 5-7 simple nerves. Corolla 5-15 mm long, usually pale to dark violet with or without a yellow blotch at the base of the lower lip but very variable and may be wholly yellow or white; upper lip somewhat narrowed above the middle, the inferior part deltoid, the superior part much narrower, oblong or oblong-obovate, widest near the rounded, truncate or retuse apex; lower lip limb approximately circular, the base with two raised, transversely lamellate or wrinkled, longitudinal crests, the apex rounded, entire or obscurely crenate; palate margin papillose; spur subulate from a conical base, with apex acute or emarginate, curved or ± straight, equal to twice as long but mostly about 1 1/2 times as long as the lower lip. Filaments curved, c. 1 mm long, the anther thecae subdistinct. Ovary globose; style cylindrical, short but distinct; stigma lower lip semicircular, the upper lip much smaller, ligulate or deltoid. Capsule globose, c. 2 mm long, the wall firm in texture, dehiscing by longitudinal, dorsal and ventral, marginally thickened slits. Seeds obovoid, slightly angular, 0.3-0.5 mm long, some or all of the testa cell periclinal walls sometimes with a ± conical papilla. Flowering more or less throughout the year, whenever the habitat is suitably wet.
