Calyx infundibuliform, inserted obliquely, with a basal spur; tube 5- or 10-ribbed; limb scarious; lobes usually awned. Corolla infundibuliform; petals cuneate at the extreme base, persistent. Stamens 5, inserted at the base of the corolla. Styles 5, connate at the base; stigmas plumose. Fruit a 1-seeded capsule, with circumscissile or irregular dehiscence.
