DENDROBIUM. 39 



SUb-varS.— candidulum (Gard. Chron. V. (1876), p. 654), flowers white 

 with the usual two orange-yellow blotches on the lip and purple spot 

 on the spur ; Mr. Elliott's (Id. p. 756), flowers more deeply-coloured 

 than the common form. 



One of the finest of Gibson's discoveries on the Khasia Hills, 

 and communicated by him to the Chatsworth Gardens in 1837 j it 

 was subsequently detected by the Rev. C. Parish in the Moulmein 

 district; it is now known to be widely distributed over Northern 

 India, Assam, Burmah, Siam and Southern China. The variety 

 rhodoneurum was sent from Moulmein, by the Rev. C. Parish, in 1867. 

 The sub-variety candidulum first appeared in Mr. Barber's collection, 

 at Spondon, near Derby ; and Mr. Elliott's, in that gentleman's 

 collection at Downs Park Road, Clapton, and also in Sir Trevor 

 Lawrence's, at Burford Lodge, but both are extremely rare. The 

 flowering season of Dendrobium Devonianum is from the beginning 

 of May to the middle of June.

 by the Rev. C. Parish; and still occasionally seen in collections. 

 Major- General E. S. Berkeley invariably found this plant growing with 

 Dendrobium albo-sanguineum on the tops of lofty trees. It flowers in 

 June and July. The specific name, from §te, " twice," and ^avOog 

 (xanthos), i( yellow," refers to the two shades of yellow observable in
