along the midribs of the ultimate divisions beneath ; veins usually once forked,

Venezuela along the Andes to Peru,—P. muHcata, Hk.,
differs from /3 principally by its lower pinnæ being conspicuously stalked at the base.
Ihis species much resembles P. dejlexa in general appearance, but may be known readily
by Its muricated rachises. A muricated plant, gathered by Dr. Spruce in the Central
Andes (Nos. 5707 and 5665), is probably distinct. The stipe is strong and distinctly
prickly, and is marked in one of the numbers as 5, and in the other as 12 feet in leno-th.
Une ot the pinnæ is 2 feet long, the largest pinnule 10 inches, and the largest ultimate
segment 1 inch long, 2 lines broad. The venation is fainter than in P. coriacea, and both
surtaces are bright-green. What appears to be the same plant is in the Herbarium from
S e ^ p FU p^ Î 9T Lieut. Norton, and these latter are the P. conacea ¡3 of
