CAMPANULACE^. 1 79 



and August. Native of very high stations on Mont Cenis 

 and the Alps generally. 



0. Elatines {Elatiiie C.) — This is a prostrate tufted plant, 

 and in most parts it is clothed with downy hairs. The flowers, 

 in loose racemes, are deeply cut into five lobes, and pale blue, 

 appearing in June and July. Native of Piedmont, and best 

 adapted for culture on rockwork in gritty loam. 



C. fragilis, syn. C. di£fusa {Brittle C.)— A tufted, diffuse, 

 dwarf plant, forming dense patches of bright-green, roundish- 

 toothed leaves, while those of the stems are broadly lance- 

 shaped. The flowers are borne in loose, somewhat leafy 

 racemes, are broadly bell-shaped and deeply divided, pale soft 

 blue. A very hairy variety in nearly all its parts, named C. f. 

 hirsiita, is peculiar in aspect, but not in any other respect diff"er- 

 ent or superior to the species. Both are tender in heavy wet 

 soils, but not so in those that are light, or sandy and dry ; they 

 are beautiful ornaments of rockwork. Native of Naples and 

 Sicily. 



C. garganica {Gargaiw C.) — Nearly related to the two last, 

 and, like them, dwarf, diffuse, and tufted. The root-leaves are 

 roundish, and deeply heart-shaped at the base ; those above 

 egg-shaped, and all toothed. Flowers in loose racemes ; azure 

 blue, with a white eye ; opening in May and June. The same 

 treatment as the last two. Much may be done by introducing 

 a few porous stones about the roots of these more susceptible 

 alpine plants in open flat borders, to reconcile them to such 

 positions ; and where the soil is naturally wet, some elevation 

 of the surface would at the same time be beneficial. Native 

 of Istria and Monte Gargano. 



C. glomerata {Cluster-fl(nucred C.) — Grows about 2 feet high, 

 with many flexuose, almost straggling stems, bearing terminal 

 and axillary heads or dense clusters of flowers. The flowers 

 are small individually, but collectively they form a large and 

 eftective 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 posi- 

 tion and rich soil. The two forms generally regarded as species, 

 named C. speciosa and C. cervicarioides^ are very closely re- 

 lated to this, if not merely varieties. The first is mainly dis- 

 tinguished from glomerata by its larger individual flowers; and 

 the second, by its taller and more straggling growth.
