Calyx campanulate, rarely tubular, truncate, 5-toothed or 5-partite, persistent, often accrescent and coloured. Corolla tube narrowly cylindric, straight or curved, often very long; limb more or less oblique with 5 spreading lobes. Stamens 4, didynamous, much exserted; anthers bithecous, ovate or oblong, the thecae parallel. Carpels 2, syncarpous; ovary incompletely 4-locular, ovules 1 per loculus attached near the top of loculus; style long, filiform; stigma shortly 2-fid.
