Hab. Feejee Islands. Samoan Islands. Luzon, Philippine Islands; 

 terrestrial. 



This is an extremely well-marked species, of peculiar habit, and of 

 frequent occurrence on these islands, in humid mountain forests. 

 The rootstock is erect, from one to 3 inches high, supported all round 

 by strong and black, wiry roots, and bearing at its summit the nearly 

 erect pinnate fronds, from 3 to 6 in number, and 6 or 8 inches in 

 length, of a harsh and firm consistence, and usually drying black ; 

 the stipe and rhachis round, not very distinctly margined, beset with 

 scattered blackish hairs. Pinnae alternate, subpetiolate, linear-oblong, 

 obtuse and obliquely cuneate at the base, the upper margin and some- 

 times the outer half of the lower one deeply incised or serrate. The 

 urceolate and nearly free indusium is seated in the sinuses of the 

 lacinise, its mouth entire ; and the straight receptacle is exserted for 

 about half its length.

 of trees. 



A well-marked species, with a slender creeping rhizoma, and fili- 

 form stipes, usually about half as long as the fronds, which average 

 from 3 to 4 inches in length, and are oblong-lanceolate in form, some- 

 times linear-oblong, and pinnatifid a little more than half-way down 

 to the rhachis, when dry of a reddish-brown colour; the segments 

 obtusely lobed, beautifully punctate-reticulated. Indusium orbicular 

 and two-valved, a little sunk in the points of the lobes ; the receptacle 

 short and included.
