Herbs or shrubs, often stellate-pubescent, sometimes climbing. Flowers 

 cymose, umbelliform, paniculate, or racemose. Calyx campanulate or rotate, 

 mostly 5-toothed or 5-cleft. Corolla rotate, the limb plaited, 5-angled or 5- 

 lobed, the tube very short. Stamens inserted on the throat of the corolla; 

 filaments short; anthers linear or oblong, acute or acuminate, connate or con- 

 nivent into a cone, each sac dehiscent by a terminal pore, or sometimes by a 

 short introse terminal slit, or sometimes also longitudinally. Ovary usually 

 2-celled; stigma small. Berry mostly globose, the calyx either persistent at 

 its base or enclosing it. [Name, according to Wittstein, from solamen, 

 quieting.] About 900 species, of wide geographic distribution. Type species:
