near the costa, a very few only extending outwards beyond a line 

 with the base of the sinus of the segments. 



A very marked resemblance exists between this and the Filix non 

 ramosa, lathis dentata minor of Plumier's Plantes de L'Amerique, t. 

 17; but the pinnae in our plant are more distant, with the points 

 less attenuated, and more deeply serrate. 



4. GONIOPTERIS GLANDULIFERA, Sp. Nov. 



Q. stipite nigro angulari basi paleaceo; frondibus pinnatis; pinnis 

 alternis subpetiolatis pinnatifidis coriaceis glabris supra nitidis, laciniis 

 oblongis obtusis margine setosis; rlxaclii sulcata; soris biserialibus 

 pilosis juxta marginem approximatis. 



Hab. Tutuila, Samoan Islands. 



Stipe about 2 feet long, stout and obtusely angular, smooth and of a 

 brownish-blade colour from the lower end upwards to the base of the 

 frond : on each margin of the front side of the stipe is a row of distant, 

 orbicular, glandular bodies, apparently abortive pinnae. Fronds pin- 

 nate, erect, about 4 feet long and 15 inches broad at the middle, of 

 an oblong-lanceolate form. Pinnae, coriaceous, alternate, and spread- 

 ing, seated on a very short petiole, towards the point of the frond 

 sessile and confluent, terminating in a long serrate pointy upper surface 

 smooth and shining, the base oblique, truncate-cuneate, and pinnatifid 

 about half way down to the costa : segments oblong, obtuse, with a setose 

 margin. Veins prominent on the upper side, the three lower opposite 

 pair of venules angularly combining. Sori biserial and approximate, 

 seated on the free venules of the segments near the margin, seldom on 

 the anastomosing venules. Sporangia sessile, and intermingled with 

 short white hairs. 



5. Goniopteris longissima, Sp. Nov. (Tab. 5.) 



G. subarborescens ; frondibus magnis pinnatis; pinnis sessilibus hor'u- 

 zontalibus subalternis approximatis coriaceis longe linearibus attenuates
