Scrophulariaceae, S.A. Ghazanfar, F.N. Hepper & D. Philcox. Flora of Tropical East Africa. 2008

Morphology General Habit: Small annual or perennial aquatic herbs, with slender stolons rooting to form new plants, glabrous
Morphology Leaves: Leaves fascicled or in rosettes, erect or floating, long-petiolate, cylindrical or with distinct lamina
Morphology Reproductive morphology Flowers: Flowers axillary, pedicels often deflexed in fruit
Morphology Reproductive morphology Flowers Calyx: Calyx campanulate, (4–)5-toothed, teeth equal or calyx ± 2-lipped
Morphology Reproductive morphology Flowers Corolla: Corolla tube cylindrical, (4–)5-lobed, almost actinomorphic; lobes ovate or ovate-triangular to lanceolate, ± pilose on the upper side
Morphology Reproductive morphology Flowers Androecium Stamens: Stamens 4 (2 short, 2 long)
Morphology Reproductive morphology Flowers Gynoecium: Ovary 2-locular; style variable in length; stigma capitate, papillose, ± 2 lobed
Morphology Reproductive morphology Fruits: Fruit capsular, dehiscing loculicidally by 2-valves
Morphology Reproductive morphology Seeds: Seeds few to numerous, minute, longitudinally multi-angular with fine transverse striations.
Note: All the species appear to be variable, and their taxonomy is imperfectly understood. Part of the problem lies is the presence of ecotypes found in deep water, shallow water and mud. This account basically follows the treatment by Glück (op. cit.), but a full revision of the genus is still required.
