Dendrobium 



DENDROBIUM. (Living on a tree.) 



Dendrobiums belong to the hottest regions of 

 the Old World, except one Australian species and 

 one Japanese. But in India there are three which 

 grow at such elevations that the cool house suits 

 them. 



If the Belgian culture be not used, they should 

 be potted in peat and moss not more than is 

 needful to keep them moist, however, and that 

 should be mixed with roughly-pounded crocks. 

 Keep them near the light. While growing they 

 need abundance of water, but not the excessive 

 quantity demanded by their sisters in the stove, 

 because the evaporation is so much less in an 

 unheated house. The quantity found sufficient for 

 Odontoglots is enough for them. They must have 

 a distinct rest ; but the wooded hills they inhabit 

 even in the tropics are not burnt up like the plains. 

 They must be watched more carefully, therefore, to 

 prevent shrivelling. Water should be given not 

 less than once in ten days, perhaps once a week. 



All flower from the upper part of pseudo-bulbs 

 made last year or in years previous. Until these 

 are quite unmistakably dead it is rash to cut 

 them off, for buds appear in their season under the 

 most unpromising conditions.
