SAXIFRAGA. 



has the saw-teeth of the leaves more acute than in S. cartilaginea, 

 where the}- are usually rather blunt. This variety is a remarkable 

 Aeizoon of ready growth and easy culture, which prevails all through 

 the Caucasus and is lavishly variable. The rosettes are larger than in 

 S. aeizoon rosea, and of a greener note, broader, more overlapping and 

 expanded, with a clearer triangle at the apex of the straight strap- 

 shaped leaf. The glandular stems are about 6 or 8 inches high, with 

 an oval panicle of flowers usually in a considerably paler tone of 

 spotless pure pink, but varying at homo alike in size and in depth of 

 tone, fading to white and deepening to purple. A garden plant sent 

 out as S. Sendtneri seems merely a form of S. cartilaginea with doubled 

 size and laxer inflorescence. It is also called S. Kol. major. 



S. catalaunica. See under S. lingulata, although it has a fair claim 

 to specific rank as a handsomo silver Saxifrage, standing, as it seems, 

 between the Lingulata typo and that of S. aeizoon. 



S. " ceratophylla " of gardens is a useful Mossy, forming vast mats 

 of fine shining foliage, finely divided, and curly like' a stag's horn. 

 This is S. Schraderi, a species in the vast series between S. hypnoeides 

 and S. sponhemica. But the name is also applied to many other 

 garden forms and hybrids that have the finely divided stag's-hom 

 foliage. The blossoms are large and white and abundant, on delicate 

 stems of 6 or 8 inches, above the rolling masses of evergreen and 

 lucent leafage. 



S. cernna requires the bog or underground-watered moraine-bed. 

 It is always a rare treasure, and has one British station only, near the 

 summit of Ben Lawers, where it exists in quantity but is as shy of 

 flowering as sometimes it is in the garden. The few basal leaves are 

 very fat, of dull fleshy -green, kidney-shaped, and cut into some five 

 shallow and wide triangular lobes. The stems are 3 inches high, 

 bearing a single large and nodding flower of pure white, and with little 

 bright -red bulbils in the axils of its little stem-leaves, which not only 

 make a brilliant effect, but scatter themselves freely about the garden 

 and make new plants. 



S. cervicornis. See under S. pedemontana. 



S. x Cherry Trees is a Burseriana hybrid of perfectly free and easy 

 growth, forming wide cheerful mats of close yellow-green spiny rosettes, 

 from which, at blue-moontide of the Greek Kalends, emerge yellow 

 moons of blossom on short stems. Sun and light poor soil seem to 

 be the only means of eliciting these ; but the neat massed carpet has 

 attractions of its own, even though it be never graced by that of 

 flower. 



S. ch/rysamtiha lives far up on the mountains of Colorado. It is
