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

    Habit
    Small annual or perennial aquatic herbs, with slender stolons rooting to form new plants, glabrous
    Leaves
    Leaves fascicled or in rosettes, erect or floating, long-petiolate, cylindrical or with distinct lamina
    Flowers
    Flowers axillary, pedicels often deflexed in fruit
    Calyx
    Calyx campanulate, (4–)5-toothed, teeth equal or calyx ± 2-lipped
    Corolla
    Corolla tube cylindrical, (4–)5-lobed, almost actinomorphic; lobes ovate or ovate-triangular to lanceolate, ± pilose on the upper side
    Stamens
    Stamens 4 (2 short, 2 long)
    Gynoecium
    Ovary 2-locular; style variable in length; stigma capitate, papillose, ± 2 lobed
    Fruits
    Fruit capsular, dehiscing loculicidally by 2-valves
    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.
