Denprozivum dixanthum. Rehb. fil. in Gard. Chron. (1865) ‘ New Plants,’ 
n. 301. 
Moulmein, that inexhaustible mine of new Dendrobia, is 
the native country of this pretty plant which was discovered 
in 1864 by the Rey. C. P. 8. Parish and sent to Messrs. H. 
Low and Co. of Clapton. It grows rapidly and flowers freely 
(in the early summer) under ordinary treatment. Untfor- 
tunately the leaves fall off the stems—old and young alike— 
before the flowers have had time to expand, a circumstance 
that detracts materially from their effect. 
In Professor Reichenbach’s otherwise accurate description 
of the plant in the ‘Gardeners’ Chronicle’ he speaks of the 
flowers as appearing singly on the side of the old stems, a 
mistake which the examination of additional examples—pro- 
duced at Knypersley and elsewhere—has enabled me to 
correct. The name is in allusion to the two tints of yellow 
which are found in its blossoms. 
In the form of its leaves—which are grassy and very sharp- 
pointed—this species resembles D. aduncum, from which 
however it is otherwise entirely distinct. 
Drscr. Stems upright or nearly so, smooth, somewhat club- 
Shaped, about half a yard high. Leaves grassy, three or four 
inches long, very sharp-pointed, falling off before any flowers
