? (No. 5); frond very large, tripinn., the segments serrulate; no fr. Savaii.

; very large, and the segments large. "Sea-coast of Tutuila," Erackenridge. 



(No. 7). Habit of Nephrodium exaltatum ; a foot high ; frond simply pinn. 



Among grass, in a natural opening at the elevation of five hundred feet on Tutuila, 



rare. 



(Chinensis, No. 8). One to one and a half feet high ; frond pinn., the segments 



appendiculate at base, the barren ones serrulate. Frequent in the lower portion of 

 Upolu and of the other islands. 



Polybotrya (No. 2) ; frond tripinn. " Upolu," Piich. 



Thelypteris (No. 2); pubescent; sori of two sizes, the larger along the nervure of partial 

 frond, the smaller along the nervures of the segments. Savaii. 



(No. 3); sori all equal. Savaii. 



(No. 4) ; sori very small. " Tutuila," Brackenridge. 



(Nephrodium); compare (No. 1) Metia. Habit of Aspid. exaltatum ; sori in two rows. 

 Tutuila. 



Aspidium ? (No. 2). Scandent on trunks of trees; frond pinn., the segments trapezoid, 

 obtuse. Savaii. 



(No. 3); frond tripinn., multifid ; the segments trapez., aristate. "Upolu," 



Brackenridge. 



Diplazia (No. 2). Four to eight feet high, and often viviparous; frond simply pinn. ; the 

 segments serrate, penninerved, the fruct. diverging from each nerve. Frequent on 

 Upolu and Savaii. 



(No. 3). Six to eight feet high; frond tripinn. Frequent in the deep forest of 



Interior Savaii. 



(No. 4). Very large ; the frond bipinn.; the stipe prickly. "Upolu," Bracken- 

 ridge. 



? (No. 5); frond bipinn.; the stipe hairy. "Upolu," Rich and Brackenridge.

 ple. Manua and Savaii. 



(No. 7); frond simply pinnate, lacerate; dent. ac. Upolu and Savaii. 



? (No. 8). Habit of A. trichomanes ; eight to ten inches high. Savaii. 



(No. 9). One to two feet high ; frond tripinn., segm. lac, inequ. Apparently 



the same species, growing six to eight feet high. Savaii. 



(No. 10) ; frond lanceolate, very long, rooting at the apex ; fr. large ; compare 



Scolopendrium. "Upolu," Rich and Brackenridge. 



Nov. gen. Asplenioid?, (No. 1). Scandent, creeping about trunks of trees; fronds pinn., 

 serrulate, penninerved; in the fertile frond, the fr. extends along nerv. to margin. In 

 the forest of Interior Savaii. 



;, perhaps distinct, growing on the ground; sori not seen. In company with the 



preceding, in the deep forest of Interior Savaii.
