in northern China, to whom its introduction to horti- 
culture is due. Struck by its suitability as a rockery 
plant, Mr. Meyer sent rootstocks to Kew, as those of a 
species of Savifraga, in 1913. Since their arrival these 
aaah have been kept in pots in a cold frame. They 
ave thriven satisfactorily and flowered freely both in 
1915 and 1916, when our drawing was prepared. Though 
it has not yet been planted out, 0. rupifraga promises 
to be quite hardy at Kew. The leaves, in autumn, turn 
brown-purple.
