72 NEPIIRODIUM, 



above pale almost silvery, one or two of the lowest pairs of 

 veinlets united, sori very copious on nearly all the veinlets 

 and on nearly all the pinnte in two rows from the rachis to 

 the apex, involucres very small convex firm reniformi-cordate 

 soon obliterated by the copious capsules. 



Ilal). Fernando Po, G. Mann. — It is with much hesitation I make of tliis a new 

 species; and yet I cannot satisfactorily refer it to any described one. Its vena- 

 tion closely resembles that of iV. mollc, but the primary veins arc conspicuous on 

 the upper side ; and it may be a gigantic and very copiously pinnated state of 

 that plant, glabrous in every part. The involucres are small, but distinctly pre- 

 sent, or I might have considered it a form of the very little understood 

 Polypodium (Goniopteris) tetragonum. The specimen is a remarkably fine one 

 6 feet long, including the stipes, wanting only the caudex. 



21. N. (Nephrodium) extensum,^\.; caudex long creep- 

 ing black (in African specimens), stipes 1-1 ^ foot long slightly 

 scaly at the base, fronds 1^-2-3 feet and more long 1-1^ 

 foot broad oblong-lanceolate acuminate submembranaceous 

 copiously pinnate pinnatifid at the apex, pinnae numerous 

 approximate subhorizontal 8-12 inches long in the broadest 

 part 4-4 of an inch wide from a broad sessile base linear- 

 oblong finely acuminated glabrous pinnatifid about half- 

 way down to the rachis, the acumen entire, segments narrow- 

 ovate or oblong or oblong-linear subfalcate entire subacute, 

 lowest pairs of veinlets angularly uniting the rest free, sori 

 copious but solitary on the veinlets between the costule and 

 the margin often strictly confined to the segments (as in Dr. 

 Blume's original specimen in my herbarium) at other times 

 extending to the lowest veinlets so that the disk is sorife- 

 rous, involucres small orbiculari-cordate glabrous often ap- 

 pearing quite orbicular and peltate. (Tab. CCXL. A.) —
