    Perianth coloured, tubular; the tube constricted briefly above its attachment to the ovary apex, then abruptly inflated into a subglobose or oblong–ellipsoid utricle, cylindrical or funnel-shaped above the utricle and straight or variously bent, expanding into a very variable, sometimes unilateral, entire or 3–6-lobed limb.
    Stamens usually 6, rarely more; anthers sessile, adnate to the stylar column.
    Ovary inferior, usually merging imperceptibly into the pedicel, usually 6-locular; style with 3–6 stigmatic lobes.
