 purple spots ; it suoeeeds well in an ordinary stove tempera- 

 ture, but reiiuires a decided season of rest by being kept dry 

 at the roots, and in a minimum temperature of 50'. The 



roots may require water occasionally during the resting period, 

 but no more mast be applied than will keep the pseudobulba

 pot should be filled to one-third of its depth with drainage. 

 The best compost is equal parts of turfy peat and sphagnum ; 

 a few bits of charcoal may be added to sweeten the material 

 when it begins to decay. A goodly supply of water is neces- 

 Bary during the growing season, with plenty of atmospheric 

 moisture. When water is applied to the roots it is as well not 

 to wet the pseudobulbs. Should it be hot and dry when the 



plant is in full growth, it will be benefited by being occasion-
