Morphology General Habit
Perennial aquatic and marsh herbs
Morphology Leaves
Leaves erect; leaf-blade with obtuse to rounded apex; base sagittate or cuneate; blade and petiole glabrous, scabrid or pubescent
Morphology Reproductive morphology Inflorescences
Peduncle longer than the leaves; inflorescence of 4–7 whorls of flowers, the lowest sometimes with 2–3 branches; upper whorls of ♂ flowers, lower of hermaphrodite and ♂ flowers; bracts 3, membranous, glabrous or pubescent; bracteoles 3 or more, glabrous or pubescent, smaller than the bracts
Morphology Reproductive morphology Flowers Calyx
Sepals 3, spreading
Morphology Reproductive morphology Flowers Corolla
Petals 3, larger than the sepals, white
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 6; filaments broadened at the base
Morphology Reproductive morphology Flowers Gynoecium Carpels
Carpels 10–30, free, ovoid; style ventral; ovules solitary, basal; abortive carpels in the ♂ flowers 0
Morphology Reproductive morphology Fruits
Achenes crowded on the small receptacle, swollen, with lateral air-chambers, ridged
Note
This appears to be very rare, and has not so far been discovered in our area. A third species, L. fluitans Graebn., with linear-lanceolate leaves and small (3 × 2 mm.) achenes which are sharply ridged and shiny when dried, has been found in the French Cameroons and S. Nigeria A genus which is regarded by some authors as being monospecific However, the differences between the two species described here are constant, and too diverse to be variations of the same species
