THE ROGKFOIL OR SAXIFRAGE 175 



similar to S. Wallace! (which see), and bears white flowers 

 in May and June. 



S. hypnoides. The " Dovedale Moss " with its emerald 

 green carpet is a well-known plant in gardens. During 

 the winter months it is one of the chief attractions in 

 the rock garden, clothing otherwise bare banks with a 

 permanent mat of beautiful foliage. In spring and early 

 summer the white flowers appear in great profusion. It 

 is a rapid grower, and small tufts planted some distance 

 apart soon meet, and make a fitting background for 

 spring-flowering bulbs. Named varieties of the Dovedale 

 Moss are numerous, one of the closest and most compact 

 being gemmifera, also known as S. Kingii (a very delightful 

 little plant), while variegata has foliage prettily variegated 

 with white and green. 



5. muscoides. This is a dwarf, dense carpeting kind, 

 forming a moss-like turf only an inch or so in height ; 

 it has yellowish flowers. S. m. atropurpurea, with bright 

 red flowers, is the original source of all the fine red hybrids 

 we have now. S. m. moschata is a stronger-growing kind, 

 with white flowers. The typical plant (S. muscoides) is 

 found throughout Arctic and Central Europe. 



S. trifurcata. This elegant plant comes from Northern 

 Spain, and makes a carpet of rosettes with three-parted 

 leaves that are of a stiffer character than most in this 

 section. It has pure white flowers on stems three inches 

 high. The variety ceratophylla, which is known as the 

 " Stag's-horn Rockfoil," has more deeply parted leaves 

 of a still more rigid character.
