Rhizome thick, oblique. Stipes tufted, 13 — 25 c.M. long, the base black, 

 clothed with black, subulate scales, the rest slender, slightly setose with 

 scattered, black bristles. Fronds 20 — 45 c.M. long, 8 — 25 c.M. broad, ovate- 

 oblong, acuminate, pinnate, gemmiferous and sometimes viviparous. Pinnae 

 ± 6 — 16 on each side below the pinnatifid apex, more or less distinctly 

 stalked, ± horizontal, acute, to ± 2 c.M. broad, crenate at the base on the 

 lower side, the upper base truncate, auriculate, the edge coarsely crenato- 

 lobate, the lobules short, to 3 m.M. long, 3 — 5 m.M. broad, decumbent, sub- 

 acute, tooth-like; lowest pinnae shorter, deflexed. Texture herbaceous; sur- 

 faces and rachis naked; colour blackish-green above, paler beneath; veins 

 pinnate in the lobules Sori on the anterior veinlets, often double, to 7 m.M. 

 long; indusium thin, decoloured, diaphanous. — [Texture subcoriaceous ; pin- 

 nae cut Vs'way down to the costa. (Bk.)].

Rhizome short, horizontally creeping. Stipes approximate, 10 — -20 c.M. 

 long, the lower part asperous, the base black, clothed with scattered, brown, 

 caducous scales, the upper part smooth, naked, greenish or stramineous. 

 Fronds 20 — 35 c.M. long, 6 — 15 c.M. broad, 2-pinnatifid, the rachis naked. 

 Pinnae 10 — 20-jugate, alternate, the central ones the largest, ± spreading, 

 broadly lanceolate, acute, cut down nearly to costa; lower pinnae rather 

 distant, somewhat shorter, deflexed. Lobes oblong, 3 — 4 m.M. broad, serrate 

 towards the apex. Texture chartaceous; surfaces naked; veins rarely forked. 

 Sori 4 — 6 on each side of the costulae, occupying the lower part of the veins.

Rhizome or caudex erect or suberect, clothed with lanceolate scales. 

 Stipes tufted, 30 — 50 c.M. long, firm, erect, stramineous or brownish, the
