Rhizome firm, creeping, scaly, the scales with a bluntish, roundish or 

 oblong, peltate base and a suddenly very long-acuminate, hair-like, erecto- 

 patent or spreading apex + l^-l'/i c.M. long. Stipes scattered, 5 — 10 c.M.

 broad, lanceolate, % — 3-pinnatifid. Pinnae spreading, lanceolate, the central 

 ones the longest, I'/j — 4 c.M. broad, deeply pinnatifid wilh oblong or linear-

 flaccid; rachis and under surface and occasionally also the upper surface hairy 

 or fibrillose especially on the costae and veins. Sori 2 — 12 to a segment, 

 very small, semicupulifoi-m or semicylindrical, placed near the centre of the 

 teeth at the base, whether or not ciliate. — Copeland distinguishes 3 forms:
