192 SUB-ALPINE PLANTS 



Campanula glomerata L. 



Stem erect, stout, 1-2 feet high, hairy. Root and lower leaves 

 stalked ; upper leaves sessile, broadly lanceolate, clasping the 

 stem by their cordate base, densely hairy. Flowers sessile, in small 

 clusters in the upper leaves, the top ones forming a dense, leafy 

 head. Corolla blue. Capsule short and broad. Calyx lobes 

 linear-lanceolate, acuminate. Very variable. 



Pastures and sides of woods from the plains up to 5000 feet. 

 In England it grows both on dry, limestone hillsides and on damp 

 alluvial soil, such as on Clifton Ings, near York. June, July. 



Distribution. — Continental Europe, Russian Asia excepting the 

 extreme north. British Isles. 



Campanula pusilla Haenke. (Plate XXIV.) 



Casspitose, with numerous tufts of leaves and slender flowering 

 stems. Stems^2-4 inches high, leafy at base, bearing a slender 

 raceme of 1-5 flowers, but more frequently the flowers are solitary. 

 Leaves of barren shoots roimdish, coarsely serrate, slightly cordate, 

 much shorter than leaf-stalk, other leaves lanceolate or linear- 

 lanceolate. Usually glabrous. Corolla pale blue, very rarely white, 

 campanulate. Calyx-teeth linear, not one-third length of coroUa. 



Gravelly, moist places and shifting screes and banks of slaty 

 detritus, especially fond of limestone, up to 9000 feet, but descending 

 beds of streams to the plains ; very common. June to September. 



Distribution. — Carpathians, Erzgebirge, Eastern, Central, and 

 Western Alps, Vosges, Jura, Pyrenees. 



C. pusilla is a very useful plant for the garden, and is grown in 

 borders or rockeries, or even on old walls. It prefers a light, 

 porous, and yet finely divided soU. 



Campanula rotundifolia L. Harebell. 



Radical leaves orbicular or heart-shaped, but they mostly die 

 away at or before flowering-time ; stem-leaves linear or narrow- 

 lanceolate, entire. Stems 6-12 or more inches high, slender, often 

 branched, with a few elegant drooping blue flowers in a loose 

 panicle, or rarely solitary. Corolla-lobes broad and rather short. 

 Capsule ovoid or globular, pendulous. Sepals subulate. 



Meadows, walls, rocks, and hilly pastures ; common. June, 

 July. It ascends to well above the sub-Alpine region. 



Distribution. — Europe, Russian Asia. From the Mediterranean 

 to the Arctic Circle. British Isles.. 



Campanula linifoUa Scop, (non Lamk.). 



Very similar to the Harebell and differing chiefly in its long, 

 reflexed calyx-teeth, and the stems are usually i-flowered. 



Clefts of rock from 5000 to 5ooo feet in Camiola and Carinthia. 

 June, July.
