only difference was that the Mount Barrow plants were larger. 
As compared with the plant just described, this form differs in 
the following respects: Stem always slender, 8 to 18 inches in 
height. Stem-leaves chiefly towards the base, rather narrow- 
lanceolate, the upper ones bract-like and small; 5 to 7 in number. 
Upper lip rarely less than 2 inches long, narrowed into a fine 
point, much curved over. Lower lip much bulging at the sinus, 
the lobes extending in. fine points to an inch beyond the dorsal 
sepal. Fruit small and narrow. To these remarks I may add 
that in the Mount Wellington plant the dorsal sepal has a pro- 
nounced indentation not far from the base, which is not present 
in the other.
