General Information

Perennial herbs, freely suspended or more commonly affixed; stolons fas- ciculate from the peduncle base, filiform, terete, to 20 cm long, ca. 1 mm thick, often mat-forming. Photosynthetic organs numerous, alternate on the stolons, to 2 cm long, sparsely dichotomously dissected into 2-6 capillary segments. Traps lateral on the segments, obliquely ovoid, 1-1.5 mm long, short stalked, the mouth lateral with the marginal simple setae, the upper lip with 2 usually long, + branched setiform appendages. Inflorescences erect, emergent, variable in length but mostly 5-10 cm long, 2-6-flowered; peduncle terete, usually less than 1 mm thick; bracts basifixed, broadly ovate, obtuse, ca. 1 mm long, the sterile scales on the peduncle 1 or 2, remote from lowermost flower; pedicels erect at anthesis, spreading in fruit, 5-15 mm long. Flowers with the calyx lobes similar, + ovate, 2-3 mm long; corolla yellow with orange or brownish marks on the palate, vari- able in size but mostly 10-15 mm long, the upper lip broadly ovate or + orbicular, obscurely 3-crenate, the lower lip usually slightly smaller, + orbicular, entire, the palate spurred, prominent, the spur + subulate from a conical base, straight or + curved, the apex obtuse or minutely bifid, about as long as the lower lip. Capsules globose, 2-4 mm in diam. dehiscing into 2 lateral valves; seeds lenticular, ca. 1 mm wide with a pronounced hilum and an irregular corky wing.
