POLYPODIUM (Evrotypoprum) vecrinatom, LD. 
Pectinated Polypody. 
Potyropium (Eupolypodium) pectinatum ; caudex moderately stout, elongated, 
horizontal, svaly, tuberculated above with the bases of the former year’s 
fronds and which are also sealy ; stipites scattered, approximate, 1-5 inches 
long, terete, blackish-brown, espetially hairy on one side; fronds decurved, 
a foot to 14 foot long, 2-4 inches broad, lanceolate or ensiform, acuminate, 
more or less attenuated at the base, pinnatifid nearly to the rachis, firm- 
membranaceous, blackish-green when dry, villosulous ; segments very nume- 
rous, horizontally patent, from a broad base which is singularly dilated up- 
wards, gradually but obtusely acuminated, entire or subsinuate, strongly 
costate, veins rather remote, internal not readily conspicuous, once or twice 
forked, sometimes anastomosing so as to form large costular ureoles, the 
lowest veinlets on the superior side soriferous; sori globose, sulphur-coloured, 
forming a continuous series on each side between the margin and the costa ; 
rachis and costa hairy, especially beneath.

This Polypodium belongs to a group of the genus whose 
species are very ill-defined, and which I suspect vary consider- 
ably, a circumstance which leads to their being needlessly multi- 
plied; but it would require more time and space than can here be
