1869.] THE MULBERRY. 133 



1 foot on simple stalks. There is a very fine companion to the blue 

 form ^ in the white variety, named C. Carpatica alba, which in every 

 respect is like the species, only the flowers are pure white. Flowers 

 from June till August. A very handsome and showy species, which 

 should be in every garden. It adapts itself to almost any position, 

 and will do well in almost any soil if moderately rich. Native of the 

 Carpathian Mountains. 



G. turhinata. — A very beautiful species recently introduced by 

 Messrs Backhouse. The flowers equal in size those of C Carpatica, 

 but are dark purple. The plant is more dwarf, but of the same tufted 

 habit of growth. Native of Transylvania. 



G. glomerata grows about 2 feet high, with many flexuose, almost 

 straggling, stems, bearing terminal and auxiliary heads or dense clusters 

 of flowers. The flowers are small individually, but collectively they 

 form a large and efl'ective inflorescence. The most common colour is 

 deep purple or violet, and of this there is a double variety. But there 

 is also a pure white sort, single and double, that is very ornamental 

 and desirable. The flowers last from June till September. Native of 

 the south-eastern counties of Scotland and the greater part of England, 

 and extends over most of Europe and Russian Asia. Fond of rather 

 a dry sunny position and rich soil. 



G. speciosa, from Siberia, is nearly related to C. glomerata, and is 

 mainly distinguished from it by its larger individual flowers and 

 flower heads. 



O. cervicaroides, from Italy, with long straggling stems, so closely 

 resembles C. glomerata that it is scarcely worth having where the 

 other can be got. 



C. aggregata, from Bavaria, is the finest of the cluster-flowered 

 Campanulas. It is about 2 feet high, with crowded clusters of pale- 

 blue flowers, which last from June till September. Like C. glomerata, 

 it delights in a warm sunny position and rich light loam. 



G. Alpina, a handsome dwarf species from the Tyrol, resembling C. 

 rotundifolia, but is more dwarf and compact, and with larger dark-blue 

 flowers. Best suited for planting on rockwork. The flowers appear 

 in July. W. S. 



THE MULBERRY. 



I hardly think the reply of R. T. D. meets the requirement of " a Subscriber " 

 in a former number of the 'Gardener.' Most trees planted in soil above their 

 natural requirements throw down a deep or tap root ; and when such is the case, 

 the tree runs into excessive growth, and becomes unfruitful ; and I believe 

 there is no remedy for this other than that of undermining the tree and severing
