Garden; and to the same gentleman the collections of the 
Royal Dublin Society and the Zoological Gardens in 
Dublin are likewise indebted for many valuable contri- 
butions. Mr. Moore informs me that one specimen pro- 
duced no less than fifteen of these singular flowers. 
Descr. The pseudo-bulbs of this species, together with 
the foliage, seem to be very similar to those of most of the 
other described Catasera. The spike of flowers is from a 
foot to a foot and a half high. Ovaries long and pedicelli- 
form, scarcely twisted. The entire blossom represents very 
nearly a depressed globe ;—the sepals ovate, acute, very 
concave, imbricated, mottled with purplish dingy brown. 
The two petals are similar in size and shape to these, but 
concealed by their closer lapping : and they are pale green, 
spotted with purple-brown. Lip very concave and ventri- 
cose, approaching to slipper-shaped, with the mouth singu- 
larly contracted, oblong, dilated towards the apex, the 
base elevated, obscurely denticulated and enclosing the 
column ;—the colour is pale green, richly spotted with 
deep purple towards the margin, and dotted with red near 
the apex. Column short, semicylindrical, pale yellow- 
green spotted with deep purple, and including the anther- 
case, not longer than the margin of the labellum. Sete 
long, purple, nearly straight.
