    Morphology

    The four tropical African species fall well within the range of variation

    Chromosome counts from European material shows the somatic numbers between 6 and 40

    All tropical African material was earlier classified as C. stagnalis Scop., but recent taxonomic work has shown that several species can be recognized based on morphological, pollen and chromosomal differences.

    Submerged plants often have lanceolate or linear leaves and long internodes, while in plants where the shoots reach the surface the internodes tend to be shorter and have rosettes of elliptic or spathulate leaves

    Terrestrial plants tend to have ovate or suborbicular leaves

    This pattern is present in all tropical African species

    The adaptation of the genus to aquatic life has resulted in the reduction of several morphological features, so that only a few reliable characters remain which can be used for identification

    In pollen, the exine surface shows the Croton pattern, which is a reticulate pattern with processes (clavae) at the intersections of the walls (muri) (Erdtman, G., 1952, Pollen morphology and plant taxonomy: Angiosperms, p. 173)

    The most useful character for identification is that of ripe fruits

    Other taxonomically useful characters, albeit unsuitable for use in species’ keys, are the morphology of pollen and the number of chromosomes
