 leaves alternate, sessile or perfoliate. Flowers large, solitary at the ends of the branches or 

 rarely 2 together, peduncled, drooping. Perianth bell-shaped or narrower; segments dis- 

 tinct, deciduous, sometimes bearing a nectary at the base. Stamens 6, free, or adnate to the

 tudinally dehiscent. Ovary 3-lobed, 3-celled, short-stalked or sessile; styles united to about 

 the middle, stigmatic along the inner side above ; ovules several in each cell. Capsule ovoid 

 or obovoid, 3-angled or 3-winged, loculicidally dehiscent. Seeds globose, 1-3 in each cavity.
