S. hypnoides {Group /., Mossy). — The common native Saxifrage, 

 with white flowers, known as Dovedale Moss, and of the easiest 

 culture. It is typical of this group. There is a more compact form, 

 S. h. densa^ and a variegated form, S. h. variegata, and another 

 variety known as S. Whitlavii. 



S. juniperina {Group III., Cushion). — Forms compact tufts of 

 dark green, spiny leaves. Yellow flowers, rather like S. sancta, but 

 produced rather earlier. A vigorous plant, but a very shy bloomer. 



S. kolenatiana {G7'oup II., Encrusted). — Rather like S. Aisoon, 



/but with pale pink flowers. A very attractive species, nearly allied 

 to S. Cartilaginea. There is a larger form, ?najor. 



S. Kotschyi {Group III, Cushion). — Forms bluish-green, densely 

 tufted rosettes, with bright yellow flowers. Quite a pretty and good 

 plant. 



S. la graveana {Group II., Encrusted). — A very compact species 

 of S. Aisoon, for a hot crevice. This species appears in catalogues 

 under the name S. La Gave Dauphne. 



S. latina {Group IV., Creeping). — Very similar to S. oppositifolia. 

 Flowers the same, but the creeping stems are more erect. A new 

 introduction. Early flowering and very desirable. 



S. Leichtli7ii {G7'oup VI. , Megasea). — Grows about 12 inches 

 high. Leaves large and crimson-coloured. Flowers rose-coloured. 

 A good species on account of its handsome foliage. 



S. lilacina {Group III, Cushion). — Makes tufts of very small, 

 hard, dense rosettes. Large, rich lilac-blue, solitary flowers on stems 

 about I inch high. It likes a partially shaded position. Of easy 

 culture and vigorous habit, this new species is likely to prove a 

 great acquisition to this large genus. 



S. lingulata {Group II., Encrusted).— M2L\ies rather heaped-up 

 tufts of blue-grey leaves, of unequal length. White flowers, in large, 

 very branching panicles. A very variable species. A most attrac- 

 tive and very beautiful plant, somewhat like a small S. Cotyledon. 



S. I. lantoscana. — A beautiful variety of S. lingulata, with heads 

 of white flowers in arching panicles. There is even a better form, 

 S. I. I. sicperba. 



S. longifolia {Group II., Encrusted). — The finest of all the silver 

 Saxifrages, making enormous rosettes, several inches across, of 

 blue-grey leaves edged with silver. White flowers in large, dense, 

 pyramidal panicles. The true S. Longifolia may be known by its 

 never making side rosettes. It takes a couple of years to come to 

 maturity, and when it flowers the plant dies, but produces seed 

 very freely. 



.5. macnabiana {Group II., Encrusted). — Forms large, rounded 



/ rosettes of narrow, rather erect leaves. Flowers creamy-white, 



lightly spotted. It is a vigorous and rapid grower, and a very
