cauline ones, with drooping, solitary, fine blue flowers ; those 

 of the English species being rather the largest, with the cau- 

 line leaves a little broader. The common name, with us, is 

 Flax bell-flower, or Hair bell. It is in flower in July and Au- 

 gust; one foot high. 



Campanula medium. Canterbury Bells. This species, 

 with its varieties, may be considered one of our oldest orna- 

 mental plants, having for a long time been cultivated in our 

 gardens ; it is, nevertheless, a showy plant, and will doubtless 

 always be retained as a prominent ornament of the border. 

 The varieties are rose, blue, and white, double and single. 

 The double varieties, however, are much inferior to the single 

 ones, and will be cultivated only for their singularity. Being 

 biennials, it will be necessary to sow the seeds every year. 

 The young plants must be transplanted to the place in which 

 they are to flower, in August or September, for if deferred until 

 spring the bloom will be greatly weakened ; the same holds 

 good with all biennials, and most seedling perennials. 



Campanula persicafolia. Peach-leaved Campanula. This 

 is one of the finest species, containing a number of beautiful 

 varieties, with large, showy flowers, more bowl-shaped than 

 the last. The varieties are single and double blue, single and 

 double white, maxima or large peach-leaved, and grandis or 

 large flowering. All of them are perfectly hardy, with hand- 

 some foliage, which makes them valuable as border flowers. 

 Stems angular ; leaves stiff; obsoletely crenate serrate ; radical 

 ones, oblong ovate; cauline ones, lanceolate linear; three feet 

 high ; in flower in June and July. 



Campanula pyramidalis. Pyramidal Bell-flower. This 

 is a grand ornament, when cultivated in perfection, forming a 

 pyramid from four to six feet high, producing innumerable 

 flowers for two or three months, if shaded from the sun. It 

 was formerly a great favorite in England, but its popularity 

 has long since passed away to give place to other more fash- 

 ionable flowers, which have in their turn also been succeeded 

 by other rivals more fair. But the old-fashioned Hollanders
