of glass, must be given to the woolly kinds. The culture 

 of all the high alpine species in perpendicular walls, 

 facing south, is to be recommended. Most seem to 

 prefer (glacialis is a notable exception) dryish cracks of 

 sunny rocks, protected from direct moisture but envel- 

 oped in a warm and humid air. But above all air, pure 

 air is their chiefest need. And unfortunately, with every 

 care, he would be a temerarious optimist to proclaim 

 any, even those that flourish, long-lived in gardens. 1 



Small plants with leaves in more or less compact 

 rosettes ; calyx campanulate, 5-toothed ; corolla-tube 

 short, constricted at the throat, limb 5-lobed. 



A. lactea (PI. LXXV). Glabrous; leaves linear- 

 lanceolate, dark green, glossy, in loose rosettes; scapes 

 slender, simple or somewhat branched; flowers 1-4, 

 large, pure white, with emarginate divisions. June-July. 

 Rocks of the Jura and some peaks in the limestone Alps 

 (Stockhorn). Excellent for rockery or pots, even for 

 borders. Only asks a porous soil and partly shaded 

 position. Developes finely under culture, and is easy 

 from seed. 



Jl. earned (PL LXXV). Differs in narrow pointed 

 leaves, downless and bluish or reddish green, smaller 

 rosettes; flowers brilliant pink. June-August. Dry, 

 rocky slopes of granitic Alps; i5oo-23oo m. The variety 

 Laggeri from the Pyrenees has larger flowers, and forms 

 a more compact green sward. Both require deep, light 

 soil, peat and sand, and plenty of sun but not scorching. 

 In these circumstances with plenty of water in dry 

 seasons, especially when the plants are young, and 

 abundant topdressing of silver sand, they are not difficult
