broad and 1 — 2 smaller ones on each side. Lobes lanceolate, acute or acu- 

 minate, the edges entire or irregularly crenate; lowest lobes (or the base of 

 the simple frond) gradually decurrent so as to form a narrow wing to 

 the upper part of the stipe. Texture herbaceous; surfaces naked or the lower 

 ± scaly on the veins ; areolae fine, copious, with free veinlets ; main veins not 

 reaching the edge. Sori small, not abundant, scattered irregularly, 1 — 7 be- 

 tween the main veins.

 ■ Rhizome creeping, the extremity clothed with black, lanceolate scales. 

 Stipes seriate, 10 — 15 c.M. long, stramineous, naked, or sparingly scaly to- 

 wards the base. Fronds deltoid, pinnatilid. Lobes divaricating, connected at 

 the base by a costal wing 2 — 3 m.M. broad, the lowest lanceolate, 10 — 12 

 c.M. long, 1 — 1 74 c.M. broad, entire or undulate, acuminate, the base decur- 

 rent on the stipe so as to form a short wing to 3 c.M. long. Texture mem- 

 branaceous; surfaces naked; veins laxly reticulate; areolae with few free 

 veinlets. Sori scattered or irregularly seriate, superficial.
