or toothed especially towards the apex, the lowest lobes a little smaller and 

 somewhat narrowed at the base. Texture firm but. not rigid; veins dislinct,, 

 forked, 8—10 on each side; costae and costulae hairy like the rachises, es- 

 pecially beneath. Sori occupying nearly all the veins except the higher ones, 

 medial; receptacle hairy, with a distinct, flat, brown, subentire, orbicular, 

 spurious indusium. — Under surface paler than , the upper one, but not glaucous.

Stipes blackish-brown, the base covered with aculeate, rough tubercles 

 and long, erect, curved, rigid, dark-coloured bristles. Fronds broadly ovate, 

 ± 100 c.M. long, + 40 c.M. broad, 5-pinnatifid, narrowed towards the base; 

 main rachis yellowish, rough, furfuraceous. Pinnae close, broadly ovate, ± 8 

 c.M. broad, sessile, short-acuminate, the rachis clothed above like the costae 

 with large scales, some of which are dark-coloured and lanceolate and the 

 others bullate or cupuliform and greyish with a black centre. Pinnulae ligu- 

 late, short-acuminate, + 5 m.M. broad, + 22 on each side below the pinna- 

 tifid apex, the lower ones shorter, cut down nearly to the costa into erecto- 

 patent, pectinate, falcate, subacute, slightly crenate lobes, with the margin 

 revolute; veins conspicuous, 4 — 5 on each side, naked or scaly. Sori minute, 

 numerous; indusium not seen.

Stipe furfuraceous at the base and covered like the lower portion of the 

 main rachis with small, prominent, aculeate tubercles with dark -red or blackish 

 points ; upper portion of the rachis clothed with long, moderately firm, coarsish, 

 brown hairs and with few, slender, yellowish, ovate, crinite scales like the 

 stipe. Fronds 5-pinnatifid, sub-5-pinnate. Pinnulae sessile, broadest at the 

 base, narrow, lanceolate, deeply pinnatifid, the point slender, subulate. Seg- 

 ments linear-oblong, distant, falcate, + obtuse, the lower ones free. Texture 

 herbaceous; under surface slightly glaucous and covered with flatfish, whitish 

 scales on the costae; veins forked. Sori occupying the whole under surface 

 of the segments. 



War. cong'esta: Segments close or imbricating, the lower ones 

 overlapping the rachis.
