    Leaves
    Leaf basal, petiolate; lamina cordate at the base, usually with conspicuous basal lobes, or at least abruptly constricted at the base; petiole ± distinct and equalling or exceeding the midrib in length.
    Inflorescences
    Inflorescencescapose with flowers racemosely arranged; bracts absent, or present and subulate to foliaceous; pedicel with or without a bracteole.
    Tepal
    Tepals blue, sometimes with a lilac tinge, fused into a short tube at the base.
    Anthers
    Anther thecae oblong to linear, dehiscing by a terminal pore.

    Pollen grains with an imperforate rugulose to granular tectum.
    Ovary
    Ovary 3-locular, semi-inferior; ovules 2 per carpel.
    Fruits
    Capsule with only one or occasionally 2 carpels developing a seed; fertile carpels globose, dehiscing by a complete longitudinal split.
