Stipes tufted. 30 — 60 cm. long, furnished with dark-coloured, hnear-

 3-partite. Lateral pinnae opposite or subopposite, short-stalked, unequal- 

 sided, with the anterior segments small, falcate, subentire, the posterior 

 ones much produced, lanceolate, acuminate, the 2 — 3 lower ones cut 

 about '/j down into falcate lobes ; central (terminal pinna deeply pinnatifid, 

 with the lowest segments T'/i — 15 cm. long, cut '/^ of the way down to 

 the costula. Texture moderately firm; surface naked above, pubescent 

 on the veins beneath; areolae with a few free veinlets. Sori scattered, 

 small, generally compital; indusium variable, reniform, curved, horseshoe- 

 shaped or nearly peltate, persistent. — The proper place of this species 

 is uncertain because of incomplete description.
