Rhizome wide-creeping, the scales dense, linear-lanceolate, brown. Stipes 

 remote, 15 — 60 c.M. long, polished, blackish, naked, scaly towards the base, 

 the scales linear-subulate, spreading, crisped, leaving the stipes rough when 

 they fall. Fronds 20 — 40 c.M. each way, 2 — 3-pinnate with a terminal branch 

 15 — 25 c.M. long, 2 — 4 c.M. broad and a few lateral ones on each side, the 

 lower ones branched again with 2 — 4 erecto-patent secondary branches. Leaf- 

 lets dimidiate or slightly inequilateral, close, the largest to + 2 c.M. long, to 

 + 1 c.M. broad, the lower edge upcurved, the upper one nearly straihgt, 

 the apex bluntish, but not rounded. Texture coriaceous; rachises hirsuto- 

 tomentose on the upper side; surfaces naked; veins terminating in the ul- 

 timate serratures. Sori obreniform, small, numerous, placed on the upper 

 and often also on the outer edge in slightly rounded hollows ; capsules spring- 

 ing from the veins and parenchyma.

Rhizome short, the scales narrow, dense, brown, narrowed gradually 

 from the base towards the acuminate point. Stipes approximate, + 30 — 40 

 c.M. long, polished, dark-purple-brown or nearly black, with the lower ^/j 

 covered with irregularly scattered, spreading, crisped, brown scales, which 

 leave the stipes rough (subaculeate) when they fall. Fronds + 20 — 35 c.M. 

 long, 15 — 30 c.M. broad, 2— 3-pinnate with a terminal branch i2— 15 c.M. 

 long, ± 3 c.M. broad, and 1—4 lateral branches on each side. Lowest 

 branches largest, erecto-patent, generally branched again at the base, with 

 the secondary branch on the lower side often the longest. Leaflets dimidiate 

 often close and imbi-icate, the largest ± 2 c M. long, + 1 c.M. broad, erecto- 

 patent, the lower line upcurved, the upper edge + straight, the apex rounded, 

 denticulate, the upper edge slightly lobed and denticulate, the base cuneate, 

 the lowest leaflets of each branch + flabellate. Texture coriaceous; rachises 

 purple-blackish, rather hirsute-tomentose on the upper side; surfaces naked; 

 veins terminating in the ultimate serratures. Sori transversally oblong or
