base, on petioles ± S c.M. long. Pinnulae lanceolate, 15 — 20 c.M. long. 

 Tertiary segments ± 3'/j c.M. long, + 1 c.M. broad, cut down to a narrowly 

 winged rachis into 10 — 12 oblong, obtuse segments on each side, which are 

 bluntly lobed. Texture herbaceous ; surfaces naked ; tertiary rachises and mid- 

 ribs with a few, longish, white hairs on both sides. Sori in the axils of the 

 1—2 lower lobes on each side of the segments; indusium distinct, mem- 

 branaceous.

Rhizome densely clothed with short, spreading fibrils. Stipes 20—100 

 c.M. long, puberulous like the rhizome but less so. Fronds to 300 c.M. 

 long, 4 — 5-pinnate. Lower piimae ovate-lanceolate, 20 — 100 c.M. long. Ulti- 

 mate segments linear-oblong, bluntisb, free or joining at the base by a very 

 narrow wing, the edges toothed or shallowly pinnatifid. Texture herbaceous; 

 surfaces sparingly artlculato-pilose, the rachises more so. Sori in the 

 ultimate sinuses.

Sori roundish or oblong, terminal on the veins, at first small and distinct, 

 afterwards more or less laterally confluent into a submarginal line. Indusium 

 semiorbicular or transversally oblong, contiguous or confluent, consisting of 

 the wholly or partially recurved, modified margin of the frond. 



Rhizome ascending or creeping, mostly short, scaly. Stipes dark-coloured, 

 not articulate to the rhizome. Fronds divided; veins free, the tips thickened.
