Stamens inserted on lower half of corolla tube; filaments much longer than anthers; anthers introrse, extrorse, or rarely latrorse, included to slightly exerted, 2-locular. Pistil glabrous. Ovary superior to slightly inferior, with many ovules per locule. Style one, base usually parted, rarely 2 separate styles; stigma capitate or 2-cleft. Capsules globose to subglobose, opening by apical loculicidal slits, 2-horned, horns terminated by a style which may be split or remain partly connate, many-seeded.
