154 ORCHIDS. 



one to three feet in length, often branched. They are of 

 easy growth. 



They should have a good supply of heat and moisture 

 in the growing season, which is from March to the latter 

 part of October. At this season the day temperature 

 should range from 70 to 80 ; the night temperature in 

 March and April, 65 to 70, and afterward 70 to 75. 



The plants may be grown in baskets, in pots, or on 

 blocks. Sphagnum moss and broken potsherds are the 

 best of potting materials. They should never- be allowed 

 to become wholly dry, as the roots are liable to shrivel 

 and the bottom leaves to fall off. They require but a 

 short season of rest, and the moss should always be kept 

 damp, but during the resting season no water should be 

 allowed to rest at the base of the leaves. 



They are propagated by cutting them in pieces, having 

 a root attached to each piece ; some are, however, easier 

 to increase than others. No collection of Orchids can be 

 complete without some of these charming plants.
