Calyx 5-partite. Corolla campanulate or suburceolate, 5-lobed, 
with 5 hairy patches inside the tube; lobes erect or spreading, over- 
lapping in bud. Cvrona none. Staminal column arising near the 
base of the corolla-tube; anthers erect, with erect membranous 
appendages. Pollen-masses solitary in each cell, minute, oblong, 
not larger than the pollen-carrier, to which they are attached by 
short caudicles. Style produced at the apex into a beak, much 
exceeding the anther-appendages. Follicle solitary (always 1), terete- 
fusiform, tapering into a beak. Seeds crowned with a tuft of hairs.
