The Dendrocoryne section of the fine East Indian genus Dendrohium forms, T)r. 

 Liudley observes, "a peculiar group, best perhaps characterized by their liaving a 

 fleshy, angular stem, with two or more manifest articulations, one or more leaves at tlie 

 nppcr end, and a lip not broken up into a tuft of hairs or fringes. They are, as it 

 were, Bolhophylla passing into Bendrohia. In the group thus limited are included D. 

 densiflorum, Gnffithii, aggregatimi, fetragonum, Veitchianum, speciosum, and some others 

 formerly placed in Besmotrichum, a species whose lip is broken up into a brush.' 



The plant here figured is certainly not among the least handsome in this hnx-ly 

 group, and was imported from India by Messrs. Henderson. It flowers in tlie spring 

 months, and is highly ornamental to the stove at that season. It requires the same 

 treatment as B. densiflora, but usually comes into blow a week later than that species.
