 die down early. Flowers larger and often a deeper blue, and 

 usually solitary. Calyx-segments linear-lanceolate or sometimes 

 subulate, erect or spreading. Very variable in size, pubescence, 

 shape, and size of flowers. Some specimens found on the Col de 

 Balme in August, 1911, had flowers ij inches across and almost 

 saucer-shaped, the corolla-lobes being very broad and shallow. 



Alpine pastures and stony, grassy places up to 9300 feet, and not 

 often seen below about 5500 feet. June to August.

 Jura, Pyrenees, Apennines, Sudetic Mountains, Arctic Russia. 



Campanula persicifoUa L. (Plate XXIII.)

 1-6 flowered. Leaves serrated, upper ones linear ; lower leaves 

 lanceolate, with long petiole. Flowers blue, rarely white, large, 

 broadly campanulate. Calyx-lobes lanceolate, half the length of 

 the corolla. Capsule erect.
