368 THE ALPINE FLORA 



long spike, erect, pale lilac-blue, lobes ciliate ; calyx 

 glabrous. Mountain woods. June-August. 



C. per sici folia. A beautiful bell-flower nearly 40 in. 

 high; flowers very large, deep glistening blue: corollas 

 widely opened, in 2-6, on long, thin stems; leaves linear, 

 crenate, finely serrate. Peculiar to wooded slopes in the 

 warmer parts of Switzerland, and a wonderful ornament 

 to the whole landscape. It succeeds in any soil that is 

 not too heavy and in partial shade, but care must be 

 taken to examine the basal rosettes, which are apt to lift 

 and cause loss of root-hold. The variety alba is a charm- 

 ing foil to the type and humosa a splendid form with 

 immense satiny bells and a double corolla. 



C. cenisia. In the high parts of the Alps, on glacier 

 moraines or in sunny heaps of earthy rubbish, one finds 

 between i8oo-25oo m. a dwarf, little campanula with 

 recumbent stem, forming charming trusses of clear green 

 foliage ; the leaves are ovate, ciliate and rosulate ; flowers 

 are solitary, of medium size, greyish or Venetian blue of 

 the shade sometimes called electric ; the cups with 

 5-deeply cut lobes are flattish, widely opened and 

 upturned. Madame Julia Correvon found in 1889 a 

 delightful variety with pure white flowers on a moraine 

 of the Valsorey glacier. It is rather difficult to establish 

 in gardens, but once at home flowers profusely, even to 

 death. The soil required may be described as artificial 

 moraine, chiefly sand and grit. Winter damp and snails 

 must be guarded against by a plentiful dressing of similar 

 grit. 



C. excisa is a curiously beautiful native of the granite 

 from among the Simplon group and near Belalp. It gets 

 its name from the small and perfectly rounded hole by 

 which the lobes of the corolla are divided as if by a punch.
