Characteristics

Terrestrial. Rhizoids capillary, simple. Stolons capillary, sparsely branched. Foliar organs present at anthesis, sparsely rosulate, narrowly linear, membranous, 1-2 cm long, 0.5-1 mm wide, 1-nerved, apex rounded. Traps few on the stolons and foliar organs, globose, 0.5-1 mm long, shortly stalked, mouth basal, upper lip with 2 short subulate reflexed appendages. Inflorescence erect, 2.5-5 cm long; peduncle filiform, terete, glabrous; flowers 1-2; scales few in the lower third of the peduncle, the lowermost usually at its very base, similar to the bracts; bracts basifixed, ovate-deltoid, acute, c. 1.5 mm long; bracteoles narrowly linear, acute, slightly shorter than the bract; pedicels spreading, usually curved, 4-8 mm long, dorsi-ventrally flattened, very narrowly winged. Calyx lobes unequal, upper narrowly ovate, c. 4.5 mm long, apex obtuse, lower similar but c. 3 mm long, apex obscurely bidentate. Corolla yellow streaked with brown, 15-22 mm long, upper lip obovate-oblong to ± orbicular, slightly longer than the upper calyx lobe, apex rounded or emarginate, lower lip much larger, up to 10 mm wide, ± orbicular, apex distinctly 3-lobed, palate scarcely prominent, spur subulate, about as long as the lower lip but widely diverging from it, usually strongly curved. Filaments filiform, ± straight, c. 1 mm long, anther thecae distinct. Ovary ovoid, style short, distinct, stigma lower lip orbicular, upper obsolete. Capsule and seeds not known.
