I formerly thought that the characters by which the following species 
is distinguished were of sufficient importance to justify me in separating 
it from Eria as a particular genus, for which I accordingly adopted Dr. 
Hamilton's manuscript name of Pinalia. Subsequent experience has how- 
ever led me to doubt the value of these characters unconnected with other 
differences, and I have accordingly reduced the genus to a subgenus of 
Eria. I may however observe that the degree of developement of the 
viscid matter by which the pollen masses cohere is greater in Pinalia than 
in any other Malaxideous plant with which I am acquainted, and that it 
exhibits an instance of a near approach to the cartilaginous gland of 
Vandee.

Different as the plants of this genus are from Dendrobium in appearance, 
it is impossible to distinguish them by characters derived from the fruc” 
tification; the distichous equitant leaves however offer an excellent mar 
of distinction.
