Dendrobium. 



A genus said to contain nearly four hundred species, very 

 many of which, and among the most beautiful of the whole order, 

 are natives of the Assam Hills. They are found for the most 

 part to thrive well in the locality of Calcutta. Several blossom 

 with drooping festoons of flowers ; these it is best to grow in 

 suspended pots or baskets. With some it answers merely to 

 attach them to the limb of a tree, binding them on with a little 

 Moss or Cocoa-nut fibre.
