Rhizome creeping, slender, filiform, covered with scattered hairs. Stipes 

 rather distant, 3 — 7 c.M. long, hairy or naked. Fronds deltoid, Novate or 

 lanceolate, 2—13 c.M. long, 1 — 4 c.M. broad; main rachis winged throughout. 

 Pinnae erecto-patent, oblong or linear-oblong to rhomboidal, cut down to a 

 winged rachis into, simple, linear, bifid or more compoundly divided pinnulae. 

 Texture thin, hyaline; surfaces glaucous or ceraceo-pruinose and covered with 

 long, jointed, or short, not-jointed brownish hairs; the edge bounded by 

 a + marginal, spurious vein; veins 1 — 2 in each segment, flanked on each 

 side by a very broad, distinctly visible stripe of darker coloured cells. Sori 

 1 — 4 to a pinna, terminal on short lobes ^e ctwcc H the barren, longer ones; 

 indusium subcorneal, the mouth + dilated or truncate.
