POLYPODIACEiE. 79 



Hab, Mount Maquiling, near Banos, Luzon, Philippine Islands. 



Both kinds of fi-onds are pinnate, and about equal in height ; the 

 sterile one with a squamose rhachis, the upper half of which has a 

 narrow marginal wing, and rooting at the apex. Pinnae alternate, 

 horizontal, 2 to 2i inches long and 6 lines broad, oblong-lanceolate, 

 with an irregularly serrate margin; the base truncate and slightly 

 auriculate; the stipe slender, about 6 inches long, sulcate and sparsely 

 squamose-hirsute. Fertile fronds shorter and narrower, with a stipe 

 one foot in length : pinnae 6 to 8 lines long, oblong or ovate-oblong, the 

 margin recurved and entire. 



Allied to Polybotrya marginata of Blume. The whole habit of the 

 plant is somewhat that of many species of Nephrolepis. 



2. POLYBOTRYA MARATTIOIDES, Sp. Nov, 



P. rhizomate scandente; stipite angulari rufo-squamoso ; frondibus mem' 

 branaceis glabris impari-pinnatis ; pinnis suboppositis sessilibus oblongo- 

 lanceolatis acuminatis serratis basi oblique cuneatis ; rhachi squamosa 

 marginata. 



Hab. Island of Savaii, Samoan Group. 



Rootstoch smooth, long, and climbing. Stipe angular, from 10 to 

 12 inches in length, with numerous small, appressed, peltate, reddish 

 scales on its surface. The fronds are ?nembranaceous, glabrous, imparl' 

 pinnate, with from 6 to 8 pairs of pinnae; which are nearly opposite, 

 sessile, spreading, oblong-lanceolate and slightly acuminate, deeply ser- 

 rated towards the point, from 4 to 5 inches long, and 10 to 12 lines 

 broad, with an oblique cuneate base. Rhachis margined, and together 

 with the costa sparsely squamose. Veins slender, parallel, simple or 

 sometimes forking close to the costa. (Fertile fronds wanting.) 



This is distinct from the preceding species, in its shorter and 

 broader frond, with fewer and larger, deeply serrate pinnae, which are 

 not articulated with the rhachis. The pinnae very much resemble 

 in their outline, some states of the pinnules of Marattia fraxinea; the
