SAXIFRAGES (ROCKFOILS). 183 



pretty class, and loves a warm spot in a chink of lime- 

 stone with loam and limestone grit. 



Ligulata, a species from Nepaul, with purple 

 flowers in spring, belongs to the Megaseas, and ranks 

 with cor di folia, crassi folia, and other large-leaved kinds. 

 The thick, shining foliage is evergreen. The variety 

 ciliata is very popular. 



Lingulata, very close to the preceding in name, 

 is widely different in habit, for it is one of the precious 

 encrusted section, known to botanists as Euazoonia. 

 It is a native of Switzerland, and forms charming 

 rosettes of silvery leaves, from which the flower-stems 

 rise to a height of fifteen or eighteen inches in spring. 

 The flowers are white with rose spots. Lantoscana, 

 described by some authorities as a species, is probably 

 a large form of it (see photograph). Superba is 

 another. These beautiful encrusted Rockfoils will 

 thrive in gritty loam in rocky fissures. 



Longifolia belongs to the same class as the pre- 

 ceding, and is a lovely plant, forming silvery rosettes, 

 from which arise in June graceful stems a foot or so 

 high, carrying white flowers spotted with red. None 

 of the encrusted Rockfoils is more beautiful than this. 

 It should be planted in a slanting position, so that 

 water does not lodge. It likes loam with limestone 

 grit, and will thrive in a moist fissure of the rocks, 

 preferably on their northern face. 



Maweana is a species from Morocco, belonging to 

 the mossy group of which hypnoides is the principal 

 type. The white flowers are borne on stems a few 

 inches high in May^ and overhang the dense cushion
