Rhizome creeping, rather woody, slender but not filiform, sparingly covered 

 with short, brown hairs. Fronds subsessile, sub tufted, erect, 1 — I'/a c.M. 

 long, + '/2 c.M. broad, ovate, subcuiieate at the base, simply pinnatifid, the 

 rachis narrowly winged. Segments 3 — 4 on each side, linear, 2 — 3 m.M. 

 long, ± */3 m.M. broad, acute, ± mucronulate, the higher ones shorter, 

 rarely produced, ± radiating. Texture thin, diaphanous; rachis and veins 

 blackish; the margin of the pinnae bounded by a blackish, thickened line; 

 veins 1 in each segment. Sori minute, 1 — 2, terminal on the higher segments ; 

 indusium campanulate, winged, the mouth 2-lipped; receptacle short but exserted.

Rhizome creeping, tomentose. Stipes S — 15 m M. long, slender, winged 

 above. Fronds lanceolate-obovate in general outline, 1 '/i — S c.M. long, to 1 Va 

 c.M. broad, 2-pinnatifid; main rachis narrowly winged. Ultimate segments 

 linear, simple or forked. Texture membranaceous; surfaces naked but the 

 veins often covered with distant, short scales ; a central vein in each segment ; 

 no spurious veinlets, but the frond bounded by an indistinct, + marginal line 

 uniting the apices of the veins. Sori solitary on the upper side of the seg- 

 ments, at the base; tube slightly winged, the mouth spreading, 2-lipped.

Rhizome creeping, densely tomentose. Stipes short, 5 — 10 m.M. long, 

 narrowly winged towards the apex. Fronds deltoid-oblong, 5 — T'/j c.M. long, 

 2^1 — 4^/2 c.M. broad; main rachis narrowly winged. Pinnae spreading, oblong, 

 cut down to a narrowly winged rachis. Lowest pinnulae again deeply pin- 

 natifid with narrow, linear, simple or 2-fid lobes to 2'/a m.M. long, ± V2 

 m.M. broad, yellow-green, purveyed with a submarginal, flexuose, slightly in- 

 terrupted spurious vein and many short, flexuose, longitudinal ones between 

 the latter and the single costa. Sori 2 — 8 to a pinna, the tube winged, 

 with the mouth 2-lipped, the lips bluntish or rounded.
