Rhizome wide-creeping, scaly, the scales brown, triangular-subulate, 

 more or less deciduous. Fronds distant, partly branched partly 

 unbranched. -- Branched fronds long-stalked, with the stipes naked, 

 dark-brown, 10 — 20 cm. long; lamina deltoid to oblong, up to + 30 cm. 

 long; branches up to + 10 on each side, erecto-patent, distant, pinnate, 

 the lower ones + 4 cm. apart, +. 10 — 20 cm. long, + 2 — 3 cm. broad, 

 sessile, broadest at or near the base, narrowed towards the apex. 

 Leaflets numerous, close, up to + 30 on each side, cut down on the 

 upper side to a filiform, decurved rachis into very slender, filiform 

 segments, the largest leaflets + 5 mm. broad; higher segments forked, 

 lower twice forked. Texture firm but not thick; surfaces and rachises 

 naked. Unbranched fronds sessile, similar to the branches of the branched 

 fronds, rather broadest at the middle. Sori roundish, small, subterminal 

 on the dilated apices of the ultimate segments, I to each segment.

(I2fl.) I., biillata, r. A. r. JR., in Bull. Btz., 1914, XVI, 20. 



Rhizome short-creeping, clothed with brown, flbrilliform scales. Stipes 

 somewhat remote, 3 — 5 cm. long, deciduous fibrillose at the base, grooved 

 above, and naked, as is the rechis. Fronds linear, + 5 — 10 cm. long, 

 1 — I'/i cm. broad, simply pinnate, narrowed gradually towards the apex, 

 rather truncate and whether or not slightly narrowed at the base. 

 Leaflets spreading, petiolulate, the largest 4 — 8 mm. long, 3 — 5 mm. 

 broad at base, the apex blunt, the lower edge entire, upcurved towards 

 the apex, the upper edge distinctly but not deeply incised into 3 — 5 

 lobes, the inner edge rather parallel to the rachis. Lobes entire or 

 emarginate, rounded when barren, truncate, somewhat retuse and often 

 irregularly denticulate at the apex when fertile, the lowest lobe of the 

 lowest leaflets sometimes free and cuneate at the base. Texture firm; 

 surfaces naked; veins simple or once forked, hidden beneath, distinct 

 above. Sori solitary on the veins or uniting the fork-branches of forked 

 veins, immersed so as to form submarginal, bullate protuberances on the 

 upper surface ; indusium firm, often irregulaiiy denticulate, bullate.
