 above, from the center of which the filiform pedicels arise. Flowers commonly 6 

 (5 or 7)-merous. Corolla rotate, deeply parted. 

 Filaments long and filiform, united at base into 

 a very short ring. Style filiform. Capsule valves 

 5, revolute. — Species 3, North America, Europe, 

 Asia. (Latin trientalis, containing one-third of 

 a foot, in allusion to the height of the plants.)
