Lentibulariaceae, P. Taylor. Flora Zambesiaca 8:3. 1988

Morphology General Habit
Aquatic or subaquatic herb.
Vegetative Multiplication Stolons
Stolons usually up to more or less 10, fasciculate at the base of the peduncle, filiform, terete, up to 20 cm.×1 mm., sometimes slightly inflated.
Morphology General Rhizoids
Rhizoids few from the base of the peduncle, often absent, filiform.
Morphology Leaves
Leaves numerous, alternate on the stolons, up to 20 mm. long; segments capillary, glabrous or sparsely setulose, simple or usually dichotomously forked from or near the base, each segment sometimes again 1–3 or rarely more times forked.
Morphology General Traps
Traps usually numerous, replacing one of the leaf segments at a fork, ovoid, 1–1.5 mm. long, stalked; mouth lateral, with 2 dorsal, long, usually copiously branched hairs and a few ventral shorter simple hairs.
Morphology Reproductive morphology Inflorescences
Inflorescence erect, 2–35 cm. high, solitary or often several arising in succession from the fascicle of stolons; flowers (1)2(6); peduncle straight, smooth and glabrous; scales absent or more usually 1 at or above the middle of the peduncle, similar to the bracts; bracts basifixed, semi-circular, semi-amplexicaul, more or less 1 mm. long; bracteoles absent; pedicels filiform, erect, (2)6–12(30) mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx lobes subequal, circular to broadly ovate, 1–3 mm. long.
Morphology Reproductive morphology Flowers Corolla
Corolla yellow, often with brown or reddish nerves, 4–25 mm. long; superior lip circular, 2–3 times as long as the upper calyx lobe, usually shallowly and obscurely 3-lobed; inferior lip usually shorter and narrower than the superior, circular, usually entire, rarely emarginate; palate much raised and bigibbous; spur conical to narrowly cylindrical, shorter than to almost twice as long as the inferior lip, the apex usually bearing a few shortly stalked glands.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments linear; anther-thecae more or less confluent.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary globose; style short but distinct; stigma inferior lip semi-circular, superior short, more or less obsolete.
Morphology Reproductive morphology Fruits
Capsule globose, 2–4 mm. in diam., dehiscing into 2 lateral valves.
Morphology Reproductive morphology Seeds
Seeds rather few (more or less 20–40), imbricate on the smooth placenta, lenticular with a broad irregular wing, 1–1.6 mm. in total diam., distal surface smooth to verrucose; hilum prominent; testa-cells small, irregular, indistinct.
