Saxifraga Kocheliana (RocTieTs Saxi- 

 frage}.^ very compact and dwarf 

 kind, allied to S. ccesia, forming dense 

 silvery rosettes of white -margined 

 leaves, with distinctly impressed dots. 

 Flowers, in spring ; white, large, freely 

 produced in corymbs on stems 3 or 

 4 in. high ; petals lance-shaped or 

 ovate, twice the length of the calyx ; 

 sepals ovate. Leaves, of the rosettes 

 tongue-shaped, smooth, ciliated at the 

 base ; those of the stem clothed with 

 clammy hairs, pale green. Alps of 



Central Europe. The rock-garden, 



in fully exposed spots, in firm, sandy 

 soil ; also for the margins of choice 

 mixed borders, in the same kind of 

 soil, surrounded by a few half -buried

Saxifraga sarmentosa (Creeping Saxi- 

 frage). Distinct in aspect from the 

 alpine or any other cultivated kinds, 

 having rather large, round, blotched 

 leaves, and graceful, slender, and long

 to 10 in. high ; petals 5, the two outer 

 ones 3 - nerved, much larger than 

 the others. Leaves, roundish-heart- 

 shaped, pilose, mottled above, red 

 beneath, on roundish stalks longer 

 than the leaves ; creeping runners, 

 which terminate in rooting offsets, 

 proceed from the axils of the root- 

 leaves. S. cuscutceformis is a variety 

 of this, with much smaller leaves, 

 petals more equal in size, and its 

 stolons or runners like those of a 



Dodder. China. The rock-garden,
