DENDROBIUM. 



clothes the trunks of the fallen trees in the hot valleys of the 

 lower Sikkim Himalayas.* Over so extensive a range the flowers 

 are found to vary considerably in size and somewhat in form, the 

 sepals and petals being more pointed, and the lip broader in some 

 forms than in others. Dendrobium Pierardi is horticulturally in- 

 teresting as being one of the first, if not the first Indian Dendrobe 

 introduced into the glass structures of Europe ; it was sent to the 

 Royal Gardens at Kew, by Dr. Roxburgh, in the early part of 

 the present century ; it is also known to have flowered in the 

 Botanic Garden, at Liverpool, in 1821 ; also in Lady Banks' 

 collection, at Spring Grove, in the same year. It is named after 

 Pierard, by whom it was introduced to the Botanic Garden at 

 Calcutta, in the first decade of the present century.
