Probably there is no plant among all the species of 
Dendrobium now known to our gardens which is more deli- 
cately beautiful than this. Its colours too are so singular as 
on that account alone to render it an object of much interest ; 
for here we have the cvanic and xanthic tints in one and the 
•/ 
same flower. We are always prepared to find red spots on a 
yellow ground, or vice versa, but it is a most unusual thing to 
find clear pure violet on petals the whole remainder of whose 
tint is yellow. In this plant, however, the combination oc- 
curs, producing a very gay and unexpected effect. 
It was sent from Ceylon, to His Grace the Duke of Nor- 
thumberland, by Mr. Nightingale, and flowered at Sion in 
August last. It has pendulous stems like those of D. 
Pierardi, hut of a delicate purple when young ; the leaves 
too are stained underneath and at the edges with the same 
colour. The flowers are as large as those of D. aggregatum, 
of a clear fawn colour, with the tips of the segments and lip 
stained with a deep rich violet. There is moreover a scarlet 
spot in the middle of the lip. 
Fig. 1. represents the outline of the lip of this plant. 
Fig. 2. shows the form of what I take to be a variety, larger.
