Characteristics

Terrestrial. Rhizoids numerous, capillary, with numerous short papillose branches. Stolons few, capillary, sparsely branched. Foliar organs not usually conspicuous at anthesis, on the stolons, narrowly linear, up to 3 cm long and 0.7 mm wide, 1-nerved. Traps few on the stolons and foliar organs, obliquely ovoid, 0.4-0.7 mm long, sessile, mouth lateral, upper lip with a prominent dorsiventrally flattened, apically rounded appendage fringed with long unicellular setae, lower lip with a shorter appendage fringed with shorter setae. Inflorescence erect, up to 55 cm long (-63 fide PULLEN); peduncle filiform, terete, glabrous throughout or minutely papillose at the base; flowers 1-15, distant; scales numerous, especially below, similar to the bracts; bracts basifixed, ovate-deltoid, 1-1.5 mm long, base shortly auriculate, apex acute or acuminate, 1-3-nerved; bracteoles linear-subulate, acute, 0.6-1 mm long; pedicels erect, c. 1.5 mm long, terete. Calyx lobes unequal, upper broadly ovate, cucullate, c. 2.5 mm long, apex rounded, scarcely accrescent, nerves c. 9, plicate, lower narrowly ovate, about as long, apex emarginate, 5-nerved. Corolla bright yellow with an orange palate and externally tinged with reddish brown, c. 10 mm long, upper lip ± orbicular, apex retuse, longer than upper calyx lobe, lower lip much larger, ± orbicular in outline, apex ± deeply 4-lobed, palate prominent, bigibbous, spur subulate, curved, acute, about as long as the lower lip and diverging from it at an angle of c. 90°. Filaments linear, c. 1.5 mm long, anthers c.   long, c. 0.3 mm wide, thecae distinct. Ovary ovoid, style short but distinct, stigma lower lip orbicular, upper minute, deltoid. Capsule globose, c. 2 mm long, firm and relatively thick, dehiscing by a ventral narrowly linear lanceolate pore. Seeds numerous, obovoid, c. 0.25 mm long, hilum terminal, distinct, testa thin, reticulate, reticulations slightly elongate.
