 Primulas, and a host of others too numerous to 

 mention. 



As an example of the method to be adopted,

 stock of Saxifraga apiculatum. Remove from

 main stem as possible. A careful examination 

 will disclose tiny rootlets attached to every 

 piece so removed, each of which, when potted 

 up in suitable soil, will grow readily. In a 

 similar way any number of rooted pieces may 

 be obtained from the mossy Saxifrages, without 

 in the least spoiling the appearance of the 

 plant from which they are taken. In deal-

 those of the encrusted section, such as diapen- 

 sioides^ Burseriana^ Boydii^ etc., more care will 

 have to be exercised, and it is advisable, before 

 removing a portion of the plant, to see if it is 

 rooted. With some Saxifrages, such as trifur-
