and bearing creamy white flowers in May. It forms 

 runners as it grows. Bryoides, which is also found on 

 the Pyrenees, is regarded as a dwarf, non-stoloniferous 

 form of it. (See coloured plate.) 



Aretioides belongs to what botanists call the 

 Kabschia section, which is of low tufty habit, and 

 includes such popular kinds as apiculata, Burseriana, 

 Boydi and Valdensis. Aretioides is a native of the Swiss 

 mountains, and is a precious little encrusted plant, with 

 bright yellow flowers on short stems in spring. There 

 is a paler variety of it called primulina. They do best 

 in loam with plenty of Hmestone grit in a rocky chink. 



Bi flora belongs to the Porphyrion section, the 

 most prominent representative of which is oppositi folia. 

 They are dwarf plants, but in the case of the two- 

 flowered Saxifrage not dense. It bears its purplish 

 flowers in May, will thrive in gritty soil, and is readily 

 increased by division. 



Boydi is an interesting plant of the tufted Kabschia 

 class to which we have seen that aretioides belongs. 

 It is supposed to be a hybrid between the latter and 

 Burseriana. It bears its yellow flowers in spring on 

 stems only two or three inches high. There is a variety 

 called alba, which flowers very freely. 



Burseriana and its variety major are gems of 

 the Kabschia section. The former is a native of 

 Carniola, and bears its creamy flowers on stems only 

 three or four inches high in winter or early spring. 

 Its charm is enhanced by the pink- tinted stems. The 

 plant spreads quickly into broad grey tufts. It likes 

 gritty limestone or loamy soil, and a Httle shade in a
