Epicalyx lobes 3-5, minute, caducous after flowering, sometimes subtended by 3-merous nectaries. Calyx cup-shaped, truncate to 5-lobed. Corolla campanulate; petals 5, yellow [or white or pink], with or without dark purple basal spot. Staminal column antheriferous throughout; apex 5-toothed, usually included. Ovary 5-loculed; ovules several per locule; style rod-shaped, 5-grooved; stigma 3-5-sulcate or rarely 3-5-lobed, decurrent. Capsule 3-5-locular, globose or pyriform, leathery or woody, dehiscent or indehiscent, sometimes slightly fleshy. Seeds 3 to many per locule, obovoid, glabrous or hairy.
