 longer than the basal portion. Stipes articulated to the rhizome. Fronds 

 divided, herbaceous, more or less copiously hairy on both sides, as is the 

 main rachis; veins free; soriferous veinlets sometimes very short and 

 then the sori apparently medial on the anterior side of the veins.

Rhizome firm, vs^oody, creeping, the scales with the base small, peltate, 

 round or oblong, the apex abruptly narrowed into a very long, subulate, 

 setiform or hair-like, spreading or erecto-patent acumen + 1 — I'/a cm. 

 long. Stipes scattered, 5 — 10 cm. long, firm, erect, pubescent, as is the 

 main rachis. Fronds lanceolate, + 20 — 60 cm. long, ± 7 '/a — 25 cm. 

 broad, 2— 3-pinnatifld. Pinnae spreading, lanceolate, the lower moderately 

 reduced, the central ones the longest, 1 Vj — 4 cm. broad, deeply pinnatifld 

 with more or less crowded, oblong or linear-oblong, entire, toothed, lobed 

 or pinnatifld, blunt or acute segments. Texture herbaceous, rather 

 flaccid; under surface and occasionally also the upper surface more or 

 less copiously hairy or flbrillose especially on the costae and veins. Sori
