230 OUR ROCK-GARDEN 



source from whence it was derived, the kindly 

 donor from whose noble rock-garden it came, and 

 our never-to-be-forgotten rambles in flower-decked 

 Switzerland. Not being a British plant, we can but 

 give it its botanical name. The specific title is Latin 

 in its origin and signifies dark-coloured, a title that 

 the deep purple-blue of its blossoms entirely justifies. 

 When in full bloom it tells out splendidly as a colour- 

 mass, and when seen in large groups the general 

 effect is charming. The stems always bear but one 

 flower, a terminal bell that is more or less pendent. 

 In Switzerland, or wherever else on the Alpine 

 range we find it, it is always partial to damp situa- 

 tions, and flowering from June to September. Our 

 own drawing we see, on reference to our diary, was 

 made on June 2ist, when the plant was well in 

 blossom. It spreads rather freely in soft soil, 

 throwing up numerous flowering stems, but one 

 pauses long before grudging it any claims it may 

 make on our hospitality. 1 Our remaining cam- 

 panula is the C. Raineri, a very charming and 

 decidedly rare Swiss bell-flower. Its vigorous up- 

 standing and broadly-open flowers and their richness 

 of colour are striking features. It is the left-hand 

 flower in the group on Plate XXXI. 



The numerous kinds of dianthus are no less ac- 



1 The C. rhomboidalis is another very common Swiss 

 plant ; one finds it in profusion on the mountain slopes 

 throughout the summer. It is figured on Plate XLVIII.
