10 LINDLEY ON PERUVIAN ORCHIDEXR. 
circle of 300 yards in circumference; while the Pines of North 
America, which attain the height of 200 feet, would singly 
occupy about a dozen acres. 
The flowers are apparently pale yellow, and very large for 
the genus. I have not been able to examine the exact struc- 
ture of either labellum or column. The stems are very short, 
and covered with loose sheaths, the uppermost of which en- 
wraps the base of the peduncle, and with it the lower part of 
a rather long petiole, with which the leaf is very distinctly 
articulated.
