A native of Ceylon, where it was discovered by the late 
Mr. James Macrae, who some years ago sent me dried 
specimens and a drawing of it. Upon the former I found a 
minute blanched portion that seemed still alive; this was 
fastened by a nail and shred to a damp shady wall in a stove 
in the garden of the Horticultural Society, where it gradually 
recovered its green colour and began to grow. By tending 
it carefully, and not feeding it until it had recovered the 
effects of its long fast while buried between two sheets of 
brown paper in a dry chest, it gradually recovered and grew 
into a plant, the offspring of which has been distributed. 
From one of them, which flowered in the garden of Mr. 
Tesina the accompanying drawing was prepared in June 
ast. ' 
The species approaches to D. Pierardi, cucullatum, and 
pulchellum, than all of which it is less beautiful, and it requires 
precisely the same treatment as those species.
