Rhizome probably creeping. Fronds + 43 c.M. long, ovate, acuminate, 

 4-pinnatipartite ; main rachis stramineous, canaliculate at the upper side. Pin- 

 nae petiolate, trapezoidal or oblong-lanceolate, the apex curved and caudato-acu- 

 minate. Pinnulae short-stalked, trapezio-ovate or oblong, the apex short, nar- 

 rowed, obtuse. Ultimate divisions trapezio-oblong, obtuse, pinnatipartite at 

 the base. Lobes spathulate-cuneate, with the upper edge crenate. Texture 

 thinly chartaceous, firm; veins thickened at the apex, covered with a calcare- 

 ous scale on the upper surface of the frond. Sori unknown.

Rhizome stout, the scales dense, pale-brown or whitish, linear. Stipes 

 erect, wiry, 10—20 c.M. long. Fronds 20 — 50 c.M. long, 10—20 c.M. broad, 

 deltoid, 5 — 4-pinnatifid. Pinnulae of the lower pinhae lanceolate-deltoid, 5 — 

 7 '/a c.M. long, 2'ij c.M. or more broad. Lower segments toothed in the barren 

 fronds, cut down nearly to the rachis in the fertile ones. Texture coriaceous. 

 Sori large ; indusium balf-cupshaped, + as long as broad, very shortly attached 

 on the sides nearly as in Humata, the apex whether or not reaching the 

 margin.

Fronds 30 — 45 c.M. or more long, 15 — 2o c.M. broad, lanceolate-deltoid, 

 2 — -3-pinnatifid ; main rachis slightly winged a'bove. Lower pinnae 10 — 15 

 c.M. long, ± 5 c.M. broad, lanceolate-deltoid, acuminate, cut down to the 

 rachis in the lower part into linear- or deltoid-oblong, blunt segments, only 

 the lowest of which are deeply toothed. Sori copious, placed obliquely in 2 

 long rows in the pinnulae near the edge; indusium broader than deep.
