margine repando-dentato ; soris rotundis uniserialibus subimmersis 

 distantibus. 



Polypodium alterni folium, "Willd. Spec. PI. 5, p. 168. 



Hab. Sandal-wood Bay, Feejee Islands. 



Stipe smooth and half round. Frond somewhat coriaceous and deeply 

 pinnatifid; its segments somewhat alternate and spreading, linear-lanceo- 

 late, attenuate to a point, the margin repand-dentate. Sori round, ar- 

 ranged in a single row, subimmersed, distant. 



This considerably resembles some forms of the preceding species ; 

 but differs in its narrower, longer and more distant, attenuated, re- 

 pand-dentate segments, with smaller sori : these are about the size of 

 mustard-seed, arranged in a single line, situated much closer to the 

 costa, and less immersed. 



21. Drynaria glauca, Sp. Nov. 



D. stipite glabro tereti basi squamoso; fronde coriacea utrinque glauca 

 profunde pinnatifida, laciniis suboppositis linear i-lanceolatis leviter 

 acuminatis; soris parvis rotundis solitariis uniserialibus. 



Hab. Mount Maijaijai, Luzon, Philippine Islands. 



Stipe from 6 to 8 inches long, about the thickness of the quill of a 

 pigeon, round and smooth, with a few slender subulate scales at the base. 

 Frond coriaceous, a little longer than the stipe, oblong and acuminate 

 in circumscription, glaucous beneath, partially so on the upper surface, 

 deeply pinnatijul : segments subopposite, distant, the terminal one the 

 longest, linear-lanceolate and slightly acuminate, or linear-oblong and 

 mucronulate (so in one of our specimens, which is perhaps distorted 

 from the attack of insects), the margin thickened. Sori small, round, 

 solitary, confined to the upper half of the frond, and arranged in a 

 single row, equidistant between the costa and margin, and continuing 

 to within half an inch of the apex of the segments.
