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

 with short, brown hairs. Fronds subsessile, subtufted, erect, 1 — !'/» c.M. 

 long, + '/a c.M. broad, ovate, subcuneate at the base, simply pinnatifid, the 

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

 long, + */, 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 — % terminal on the higher segments ; 

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



New Guinea.

Rhizome creeping, tomentose. Stipes 5 — 13 m BI. long, slender, winged 

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

 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—7 '/j c.M. long, 

 2Vj — 4'/j 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'/, m.M. long, + '/^ 

 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.
