SUb-var. — candidum, flowers white, except the orange-yellow disc of lip, 



on which are two light red-brown blotches near the base.

Two distinct forms of this superb Dendrobe, received from two 



different localities, are known in gardens ; one from Burmah, with 



long stems that produce large flowers, and the other from Assam 



Dendrobium Wardianum. 



and the Khasia Hills, with shorter and more slender stems, that 

 produce smaller flowers with brighter colours than the Burmese 

 form. The Assam form was introduced first ; it was collected by 

 Simons, about the year 1856, and one of the plants sent home 

 by him flowered in Messrs. Jackson's Nursery, in the spring of 1858, 

 and was figured and described in the Botanical Magazine as a variety 

 of Dendrobium Falconeri. About the same time, or in the following 

 season, a plant (whether one of Simons' or not it is not stated) 

 flowered in the stove of Dr. Ward, at Southampton, which showed 

 a more marked deviation from D. Falconeri than that figured in
