- P. tentaculata (Restrepia tentaculata. 
jppig, t. 59.)—I do not perceive in what 
respect this plant differs from Pleurothal- 
lis, with which it corresponds in habit, in 
the adhesion of its lateral sepals, and in 
having only two pollen-masses ; the latter 
is the only point in which Restrepia ap- 
pears to me really to differ from Pleuro- 
thallis. To be stationed next. P. grandi- 
ra.

from Cuchero agree very well with the de- 
between my sections of Pleurothallee and 
cal, although not the natural distinction 4

Very near the last, from which it appears, 
from the plate in Póppig's work, to | iffer 
in having smaller flowers, with the lat : 
sepals quite distinct to the very base, 
with the labellum of another figure.
