żin. to Zin. long, gin, broad; lower pinne lft. to 14ft. long, 6in. to 
Yin. broad, with numerous lanceolate pinnules on each side, which 
are cut down to a broadly-winged rachis into lobes about In. long 
and jin. broad ; rachis and both surfaces hairy. sori lateral in 
the ultimate lobes, but not reaching the apex. West Indies.

central pinnz lanceolate, caudate, pinnatifid, with numerous 
similar pinnules; lowest pinne deltoid, with pinnules often 
2in. long, and again pinnatifid. sori not — the tips of the

P. macroptera (large-winged). sti. lft. or more long, raked, 
erect, straw-coloured or brownish. fronds 2ft. or more long, lft. 
to 14ft. broad, cut nearly to the rachis in the upper part into 
numerous linear lobes, the lowest of which are 6in. to 9in. long 
and żin. broad, with about lin. between them at the base, the 
oint gradually narrowed and very faintly toothed when barren ; 
. lateral pinne few, often only a single pair, like the terminal one, 
but smaller. sori not reaching the tips of the segments. Brazil. 
Syn. Litobrochia macroptera. 
P. Milneana (Milne’s). sti. strong, erect, yellowish-brown. 
fronds 2ft. to 3ft. long, with numerous pinne on each side, cut 
down throughout nearly to the rachis into linear-oblong, falcate 
lobes, šin. to jin. long; lowest pinne 6in. to Qin. long, lin. to 
l}in. broad, with a single similar, but smaller, pinnule at the 
base on the lower side. sori falling short of the sub-entire tips.
