SAXIFRAGA. 



of W. A. Clark ; L have heard of Gloria grown consistently, and 

 evid< atly with success, in the fullest sun ; I have seen all forms turn 

 green and tired from a sunless summer ; and finally, in the alpine 

 climate of West Yorkshire no Burseriana gives any trouble anywhere, 

 but remembers the Salum Klainin with equal stoicism in sun or shade, 

 loam or underground-watered moraine-bed. As for 8. Burseriana 

 elegans, this stands so remote from the type, in its outbreak into 

 flowers of a very dim pink, that it hardly deserves to bear the family 

 name undifferentiated, and will be found, accordingly, under a 

 heading of its own as S. elegans. (It has now, indeed, received 

 separate rank as 8. Irvingii.) 



S. x bursicidata is the hybrid between 8. Burseriana and 8. xapi- 

 cidata. Its inflorescence is rather that of an enlarged loosened 

 S. apiculata. with Burseriana-white flowers, but in a slackened head, 

 carried on sieras of 3 or 4 inches, above cushions of glaucous spines, 

 after tho style of 8. Burseriana. It is a fine and easy novelty. 



8. caesia, as sent out by some nurseries, is 8. striata, q.v. — a specially 

 neat and brilliant sub-species or hybrid of S. incrustata. 



S. caesia, L. (sometimes sent out as 8. recur vi folia, Lap.), is the 

 commonest of the choice wild Kabschias, alike in cliff and in cultiva- 

 tion ; and always one of the most delightful, with its crowded masses 

 of tiny packed rosettes, built of broad recurving little leaves, dark and 

 leathery, brightly pitted with lime ; and its thread -fine delicate stems 

 of 3 or 4 inches, bearing each a loose spray of charming milk-white 

 round-rayed stars. In cultivation it is quite easy on rock-work or 

 moraine, liking a rather cool place, as a rule, and of course, like all 

 its kindred, clamouring for lime. Where found in the Alps it is usually 

 abundant ; the form sent out sometimes as 8. c. major being a form 

 prevalent at high altitudes in the Dolomites, whereas the ordinary 

 type is abundant in company with 8. squarrosa, lower down. In the 

 screes above the Antermoja Lake, for instance, and on the Forcclla 

 Lungieres, the Major form prevails — a splendid thing about twice the 

 size of the type in leaf and flower and all parts, with the rosettes more 

 loosely built and compiled. 



S. caespitosa. — The true species is almost unknown in cultivation, 

 though tho name is often given in catalogues to its hybrids, or to forms 

 that shade out of it towards S. decipiens or S. hypnoeides, between 

 which the plant stands undecided — a difficult species, and not attrac- 

 tive, requiring to be pulled to pieces or raised from seed anew every 

 year, and in appearance exactly suggesting a small tight mass of 

 S. hypnoeides, without any barren runners, but formed into cushions 

 of almost hairless tri-cleft little leaves, conspicuously broader and
