A highly curious and extremely rare epiphyte, found in 
Ceylon by Mr. Watson, the Superintendant of the Govern- 
ment Garden at Peradenia, and transmitted by him to the 
Horticultural Society. It has very much the habit of a Geo- 
dorum, only it has pseudo-bulbs, instead of tubers. 
* A name, the meaning of which is not explained by its author, Dr. Blume.
