DENDROBIUM. 



Originally discovered by Wallich in the early part of the present 

 century, growing on moss-covered trees in the hot, damp valleys of 

 Nepaul, and introduced by him about the year 1828 — 29 ; it 

 flowered for the first time in this country in Messrs. Loddiges' 

 Nursery in 1830. It was collected on the Khasia Hills, in 1836, 

 by Gibson, while on a mission to India for the Duke of Devon- 

 shire. It is sparingly spread over the lower Himalayan zone from 

 Nepaul to Assam, where its vertical range is 2,500 — 3,500 feet. 

 The variety Schroederi first appeared in the collection of Mr. J. W. 

 Schroeder, at Stratford Green, Essex, and has ever since been 

 recognised as one of the most beautiful of Dendrobes. The flowering 

 season of Dendrobium densiflorum is from March to May.
