Terrestrial. Rhizoids few, capillary, basally thickened, with numerous papillose branches 0.5-1 mm long. Stolons few, capillary, branched. Foliar organs usually conspicuous at anthesis, rosulate and on the stolons, obovate to narrowly oblong, membranous, up to 2.5 cm long, 2-4 mm wide, multinerved, apex rounded. Traps on the vegetative organs, globose, 0.5-1 mm long, shortly stalked, mouth basal, upper lip with 2 simple subulate appendages, lower lip with 1 short obtuse appendage. Inflorescence twining, up to 30 cm long; peduncle filiform, terete, glabrous; flowers 2-6, distant; scales numerous, similar to the bracts; bracts basifixed, ovate, acute, 2-3 mm long; bracteoles subulate, shorter than the bract; pedicels erect or spreading, filiform, 10-15 mm long, narrowly winged. Calyx lobes subequal, ovate to broadly ovate, 4-5 mm long at anthesis, up to 7 mm long in fruit, upper slightly larger, apex obtuse or subacute, lower shortly bidentate. Corolla yellow, 11-20 mm long, upper lip orbicular, longer than the upper calyx lobe, 7-12 mm wide, apex rounded, lower lip ± orbicular, up to 15 mm wide, apex emarginate, palate very conspicuously raised, gibbous, extending almost to the apex of lower lip, spur subulate, straight or slightly curved, about as long as but widely diverging from the lower lip. Filaments linear, curved, c. 1.5 mm long, anther thecae subdistinct. Ovary ovoid, style relatively long, stigma lower lip orbicular, deflexed, upper lip obsolete. Capsule broadly ovoid, dorsi-ventrally compressed, uniformly membranous, 4-5 mm long, dehiscing by dorsal and ventral longitudinal slits. Seeds numerous, ovoid, c. 0.4 mm long, testa conspicuously coarsely reticulate, reticulations elongate.
