in the atmosphère should also be abundant, and the température should range 
from io° to 14 0 Centigrade (50° to 58° Fahrenheit) in winter, and from 18 0 to 
20° C. (65° to 70° F.) in summer. 
During the period of growth the plants require copious waterings. After the 
flowering period, they should be allowed to undergo a period of repose for some 
little time, during which the waterings should be reduced to that strictly neces- 
sary, and afterwards, as they increase progressively in activety, the amount of 
water at the roots should be gradually augmented, until the pseudobulbs hâve 
arrived at maturity. At this epoch — we speak of September to October —- care 
should be taken to let the plants hâve as much sun as possible, so that the 
growths of the year should be thoroughly ripened. Lastly, they should hâve a 
good rest, from the end of November to about the end of February.
