ALPINE PINKS 139 



D. cal-alpinus. This is a beautiful kind, a hybrid 

 between D. callizonus and D. alpinus, and has big rose- 

 coloured flowers zoned with crimson. It may be grown 

 in the same positions as the latter, and is raised from 

 cuttings. 



D. callizonus. An exquisitely coloured Pink, with large 

 crimson flowers marked with carmine, on stems about 

 two inches high above neat grey leaves. It is a most 

 tantalising plant. It likes a cool and shady place, 

 and well-drained sandy loam, among stones ; it needs 

 plenty of water in summer. It often dies off without any 

 apparent cause. Increased by seeds, when obtainable, 

 or by cuttings. 



D. dentosus (Toothed Pink). Quite a rare rockery 

 plant from Southern Russia. The writer has it on a 

 level sunny part of the rock garden, in loam, sand, and 

 grit, with about half an inch of fine gravel on the surface 

 round about the plant. It has large leaves and violet- 

 lilac flowers with a deeper band. Increased by seeds or 

 cuttings. 



D. microlepis. A charming little Pink with distinct, 

 stiff, glaucous foliage and tiny flowers varying from 

 rose-purple to white. Best in the moraine or in 

 peat and loam. Lime, though often recommended, is 

 not essential. Should be kept rather cool in summer 

 if in dry soil. Increased by division or seeds. 



D. glacialis (Glacier Pink). This treasure is the despair 

 of many cultivators of alpines. Its home is on the Alps 

 of Europe. It forms a close carpet of glossy leaves,
