Rhizome strong, wide-creeping or climbing, the apex clothed with brown 

 hairs. Stipes 5 — 10 m.M. long. Fronds lineai'-lanceolate, 15 — 30 c.M. long,

 Pinnae short-stalked, the upper ones sessile with a narrowed base, the lower 

 ones 2 X as long as broad, the apex rounded, the barren ones toothed, inciso- 

 dentate or -crenate or irregularly pinnatifid '/a'way down or more, the stalks 

 winged, the base obliquely cuneate, the lowest anterior lobe often prolonged; 

 central ribs pinnate. Fertile pinnae more deeply pinnatifid, sometimes con-

Rhizome fdiform, sparingly clothed with spreading hairs. Stipes filiform, 

 brown, 5 — 6 c.M. long, covered with short hairs. Fronds 6 — 15 c.M. long, 

 1 — 2'/2 c.M. broad, obovate-oblong, cut down to a winged rachis. Segments 

 erecto-patent, + 5 — 10 c.M. long, to + 2 c.M. broad, simple, forked or 

 pinnatifid. Lobes erecto-patent, to ± 3 c.M. long, 1 % — 2 m.M. broad, simple 

 or divided again, the apices of the ultimate segments bluntisb or rounded. 

 Texture thin ; surfaces naked, but the margin of the segments sparingly ciliale 

 with short bristles. Sori terminal; indusium obconical, sunk, the mouth fur- 

 nished with deciduous hairs.
