SAXIFRAGACE/E. 1 35 



North America, and is British. It flourishes best in moist 

 sandy soil, on rockwork, or in the mixed border. 



S. Aizoon {Aizoon S). — This is one of the group with en- 

 crusted leaves. The leaves are produced in rosettes, are blunt, 

 tongue-shaped, margined with close sharp teeth and a grey 

 encrustation. The flower-stems are about 9 inches or i foot 

 high, branching near the summit, and bearing on each branch 

 several greenish-white flowers in July and August. Native of 

 the Vosges and Bohemia and the Alps, generally on moist 

 rocks. In flower the plant is comparatively valueless; but the 

 grey rosettes of leaves prettily ornament rockwork in sunny 

 moist positions ; and the rosettes, carefully divided and culti- 

 vated for the purpose, are useful also for edgings and geometric 

 lines in the flower-garden. It prefers light, rich, moist soil ; but 

 succeeds fairly in different kinds, if not stagnant and heavy. 



S. Andrewsii {Ajidrew's S.) — This sort has somewhat of a 

 mongrel aspect. It has the tongue-shaped leaves and rosette 

 arrangement of the encrusted species, but the margins lack 

 the characteristic serratures of that group, and have instead the 

 regular, blunt, and conspicuous teeth of the London Pride S., 

 and the bright intense green of that species, along with the 

 faintest tracing of the grey incrustation peculiar to the others. 

 In the flowers and flower-stems there are other resemblances to 

 the London Pride S. ; but the style of inflorescence is more like 

 that of some of the encrusted kinds, being more rigid than that 

 of London Pride. It is a very handsome plant, and very ac- 

 commodating as regards soil and position, doing well in any. 

 It is without any authentic history, but is supposed to be a 

 hybrid, and was first discovered in Ireland. 



S. aretioides {Arctia-like S.) — A very diminutive species. 

 The leaves are small, linear, widening somewhat upwards, 

 arranged in tiny rosettes and covered with a grey incrustation. 

 The flower-stalks are i inch or 2 high, clothed with glutinous 

 hair, bearing a compact corymb of few golden-yellow flowers. 

 Flourishes best on rockwork in light sandy loam, in a sunny 

 but moist position. Flowers in June and July. Native of 

 lofty rocky stations on the Pyrenees. 



S. biflora {Tiuo-flo7uered 6".)— This is one of the opposite- 

 leaved group. It forms straggling mat-like masses of weak, 

 prostrate stems, crowded with small, thick, dark -green leaves, 

 widening a litde towards the point. The flowers are produced 

 on short erect branches, in heads of two or three together ; 

 they are large, deep rose, and appear in July and August. 

 Native of the Alps and Pyrenees, in the loftiest positions at 

 snow-line. Adapted best for sunny moist positions on rock-
