Specimens of this tree in fruit have been several years in my herba- 
rium, but I never had the good fortune to detect the flowers until this 
year (1852) ; the male flowers are still unknown.

One of those singular-looking epiphytes, of which the stalked Den- 
drobia exhibit so many examples in this country, where a beautiful and 
showy inflorescence seems to be strangely engrafted on an apparently 
withered and lifeless twig. This twig during the first year of its 
growth is of a lively green and clothed with leaves; these afterwards 
fall off, leaving only their sheathing bases, which envelope the stem in 
a grey, membranous, dead-looking covering. It is when in this state 
that the plant now described is ornamented with its beautiful, highly- 
polished, rose-coloured flowers; at the end of the third year, when the 
- plant has perfected its fruit, the membranous sheaths fall off, and the 
stem dies, new shoots springing from the base, to go through a similar 
course. The pedicels of this plant are rose-coloured, like the flowers ; 
across the front of the column, and below the orifice of the stigmatic 
cavity, there is a small crest, terminated on each side by a deeply- 
coloured horn, two- or three-toothed at the apex—these are doubtless
