linear attenuated below deeply pinnatifid, the segments sub- 

 ovate or dentiform, fertile ones liearing the sori on the 

 changed caudate and generally more, or less entire usually 

 falcate extremity, the very aj)ex sometimes sterile and pin- 

 natifido-serratc, veins solitary in each lobe soriferous in the 

 fertile portion at their base clulibed at the apex, sori oblong 

 soon confluent. — Metten. Folypod. p. 32, Grammitis, Sv).

 variable species it must be confessed, and I fear my X. Jamesoni is one of the states 

 of it. 



31. P. (Eupolypodium) setosmn, Metten.; caudex short 

 creeping scaly, fronds here and there imperfectly setose 

 tufted 1-2 inches high 1 line wide coriaceous rigid scarcely 

 stipitate linear-lanceolate obtuse dentato-pinnatifid for its 

 whole length, upper half soriferous. — Metten. Polypod. p. 33.

 the author in my herbarium is P. serrulatum. 



Ilab. Brazil, Jiaddi. Organ Mountains, Gardner {without number). — This Avants 

 the caudate and nearly entire fertile apex ; the teeth or segments of the barren 

 aiul fertile portion are uniform : perhaps a mere variety of serrulatum. At any 

 rate Raddi has considered the two as one, and the figure of Schkuhr, so generally 

 quoted for that supposed species, seems identical with setosum. 



32. P. ? (Eupolypodium) binerve, Hook. ; caudex creep- 

 ing ? (a dense mass of tufted fibres only appears on our spe- 

 cimen, concealing the rhizome), stipites scarcely any, fronds 

 nearly sessile very numerous CcEspitose 3-6 inches long ] of 

 an inch wide firm-membranaceous lurid-green linear sub- 

 flexuose or a little falcate deeply pinnatifid nearly to the ra- 

 chis, lobes ol)long- or rotundato-quadrate, the narrower ones 

 with a single rarely forked vein, the broader ones with tno 

 distant parallel undivided straight veins clavate at the apex
