Corolla salver-shaped, white, pink or yellow, tube narrow; lobes 4-12 or more, spreading, imbricate. Stamens 2; filaments very short; connectives usually mucronate. Carpels 2, syncarpous; ovary bilocular; usually 2 ovules per loculus, near the base; style cylindric; stigma linear or capitate, ultimately usually 2-lobed.
