above the rim of the pot, with a layer of small 

 pieces of turfy peat placed upon the outside, 

 to keep the mould together. This may be se- 

 cured by the means of small pegs thrust through 

 them into the mould. Care must also be taken 

 while potting that the base of the pseudo-bulbs 

 is not covered ; for if planted too low, they sel- 

 dom make much progress, being so liable to 

 damp off when making the young shoots. 



The best and most proper time for potting is 

 when they have commenced growing, or at least 

 when they have begun to form new roots. The 

 plant should be made firm after potting ; no 

 water should be given them until they have 

 made a good progress in their growth, as the 

 moisture of the house will be sufficient for 

 them during the time I have specified. After 

 that water may be given cautiously at the first, 

 increasing by degrees as the plant becomes more 

 established with roots. A little syringing occa- 

 sionally will be beneficial to them ; but as soon 

 as they have nearly completed their growth, the 

 water must again be reduced, so as to bring 

 them into a regular dormant state. No water 

 will be required for them whilst they are at rest, 

 if placed in a cool house. The temperature while 

 growing should range from 70° to 80*^ for the 

 first three genera; and for the latter from 65° to 

 70', falling to 50° or 55° for the resting season.
