Rhizome creeping, grey-brown. Stipes slender, stramineous, 6 — 8 c.M. 

 long, naked, or provided with blackish setulae downwards, winged nearly or 

 quite to the base. Fronds oval, + 40 c.M. long, ±18 c.M. broad, deeply 

 pinnatifid. Terminal lobe ±18 c.M. long, caudate; lateral lobes ± 4—5 on 

 each side, ± 2—3 c.M. apart, ± 10 c.M. long, ± I'/a c.M. broad, caudate, 

 connected by a costal wing ± 1 ^j^ c.M. broad, the sinuses broadly rounded, 

 the lowest lobes decurrent into the wing. Texture flaccido-papyraceous, hyaline ; 

 colour pale-green; surfaces naked; costa and costulae distinct, stramineous; 

 main veins slender, curved, indistinct near the edge; areolae numerous, with 

 included free veinlets. Sori numerous, rather small, roundish, irregularly 

 2^-3-seriate, not immersed in pits.

Rhizome woody, the scales roundish, oblong when young, entire, adpres- 

 sed, dark-brown, deciduous. Stipes ± 20 — 43 c.M. long, firm, glossy. Fronds 

 30 — 120 C.M. long, 15 — 30 c.M. or more broad, cut down into few or seve- 

 ral spreading or erecto-patent lobes on each side. Lobes linear, acuininate to 

 caudate, ± 1 — 4 c.M. broad, connected at the base by a costal wing '/a — ^■ 

 c.M. broad, the sinuses rounded; lowest lobes decurrent so as to form a nar- 

 row wing to the stipe. Texture papyraceous; surfaces naked; primary veins 

 flexuose, becoming gradually finer towards the margin, uniting several times 

 so as to form ± 3 series of alternate, ± hexagonal primary areolae; secon- 

 dary areolae numerous, fine, indistinct, with copious free veinlets. Sori su- 

 perficial or immersed, in 2 — 5 rows on each side of the central ribs of the 

 laciniae.

Rhizome stout, creeping, the scales large, lanceolate, glossy, ± black, 

 subcoi'iaceous, not hair-pointed. Stipes 13 — 25 c.M. long, naked, glossy, on 

 short branches of the rhizome. Fronds 15 — 45 c.M. long, 20 — 30 c.M. broad, 

 cut down to a broadly winged costa into 6 — 20 pairs of segments. Seg- 

 ments 1 — 3 c.M. broad, a little serrulate, acuminate, the lowest pair generally 

 deflexed and either a little decuiTent on the stipe or scooped out and sub- 

 cordate at the lower bas6, sotnetinies quite spreading as are the other seg-
