68 DENDROBIUM. 



smaller pseudo-bulbous tribe ; these will require 

 billets of wood, whicli should be either oak or ash, 

 and the rougher the bark the better will the plant 

 root on it; these, before using, should have a slight 

 covering of long sphagnum, secured down with 

 lead wire. I prefer this to placing them on 

 the bare billets, as moisture remains longer about 

 their roots, which is most essential while the 

 plants are growing ; the other part of the treat- 

 ment is the same as that for the first section. 

 The temperature for the whole, while growing, 

 should range from 70° to 80", but when at rest it 

 may fall as low as 55° or 60".
