Distinguished from all other plants by the corolla — a 

 tube narrow in the middle, inflated at the base (round the 

 ovary and stamens), and enlarged again at the tip and 

 there closed in except for five lens-shaped openings. 



Herbs or woody plants with tuberous rootstock and 

 opposite ovate lanceolate or linear (not cordate) leaves. 

 Flowers in axillary peduncled, umbel-like cymes. 

 Corolla tube dilated at base and apex: lobes five, 

 connate by their tips (and thus leaving openings be- 

 tween). Corona five or ten-lobed, with five scales or 

 processes inside opposite the anthers. Anthers incum- 

 bent on the stylar head, without membranous tip. Pollen 

 masses one in each anther-cell (ten in all), erect, sessile. 

 Follicles slender, smooth, terete.
