 oblong-campainilate, not inflated, 4-S-toothed, 8-lo-ribbcd. Petals 4 or 5. much exceeding 

 the caly.x, each with a 2-cleft appendage at the base of the obovate emarginate blade. 

 Stamens 10, exserted. Styles opposite the calyx-teeth, alternate with the petals. Capsule 

 several-celled at the base, its teeth as many as the styles. [Latin, glutinous.] 



About 5 species, the following of arctic and subarctic regions ; the others European and .\siatic.
