Information
Terrestrial herb. Rhizoids and stolons capillary, numerous from the base of the peduncle. Leaves few, usually decayed at anthesis, leaf-opposed on the stolons, linear, up to 2 cm. ×0.5–15 mm., 1–3 nerved. Traps numerous, globose, shortly stalked, glandular, 0.6–1.0 mm. long; mouth basal, with 2 dorsal simple subulate appendages. Inflorescence erect or usually twining, 5–40 cm. high; peduncle filiform, glabrous; flowers 1–6, usually distant; scales few, similar to the bracts; bracts basifixed, broadly ovate, more or less 2 mm. long; bracteoles linear-lanceolate, usually shorter than the bracts; pedicels erect or ascending, 2–15 mm. long, flattened or more or less narrowly winged, usually longer than the fruiting calyx. Calyx-lobes subequal, 3–6 mm. long, with apex of upper acute, of lower minutely bidentate. Corolla usually violet with a dark blue, greenish, yellow or white spot in the throat, rarely wholly yellow or white, 5–10 mm. long; superior lip narrowly oblong; inferior lip circular; palate raised; spur subulate, usually curved, acute or rarely obtuse. Filaments linear; anther-thecae subdistinct; ovary ovoid; style indistinct; stigma-lips short, truncate, subequal. Capsule narrowly ovoid, dehiscing by longitudinal ventral and dorsal slits, capsule-wall of uniform thickness. Seeds numerous, globose, 0.3–0.35 mm. in diam.; testa thin, cells distinct, more or less isodiametric.
