Bearded Campanula. No other Bell-flower has little projec- 

 tions between each of the five teeth of the calyx which are 

 turned back towards the stem. Only one other Bell-flower 

 (Campanula Zoysii), and that a species not always recognised 

 as distinct, has a light blue corolla with long hairs around its 

 mouth. But here there is a constriction just immediately 

 below the opening of the bell, and the plant is smaller and very 

 rare, and occurs only in Eastern Switzerland.
