Flower solitary, terminal, actinomorphic, often brightly coloured, usually funnel-shaped, with two spathe-valves; tube usually very short; lobes usually equal, more or less spreading. Stamens symmetrical. Style-branches 3, usually deeply bifid. Capsule shortly cylindrical or ellipsoid, coriaceous. Seeds numerous, globose or angled.
