Calyx 5-partite. Corolla very deeply 5-lobed, rotate or reflexed ; 

 lobes overlapping to the left in bud. Corona of 5 lobes arising from 

 the base of the staminal-column and alternating with the corolla-lobes, 

 obconic or trumpet- or slipper-shaped, with infolded margins, forming a 

 channel or a narrow funnel-shaped cavity within, truncate or rounded 

 at the apex, with a horn directed forwards over or towards the anthers. 

 Stamens arising from the base of the corolla, united into a tube around 

 the ovary and style. Anthers with a terminal membranous appendage 

 inflexed over the apex of the style ; pollen-masses pendulous, solitary in 

 each cell of the anther, attached in pairs to the pollen-carriers by 

 slender caudicies. Follicles lanceolate, more or less beaked and more or 

 less echinate. Seeds crowned by a tuft of hairs. — Perennial twining 

 herbs with shorter stems. Leaves opposite, petiolate, cordate. Flowers 

 small, arranged in pedunculate umbel-like corymbs, lateral at the nodes.
