Stipes 15 — 25 c.M. long, erect, naked, dark-brown or blackish, polished. 

 Fronds 15—45 c.M. long, 10 — 25 c M. broad, + deltoid in outline, 3 — 4- 

 pinnate. Leaflets suborbicular, broadly flabellate, rather equilateral, the base 

 straight, rounded or broadly cuneate, the outer edge rounded, broadly and 

 shallowly lobed. Texture thinly herbaceous to papyraceous ; rachis and sur- 

 faces naked; veins terminating in the ultimate crenations or serralures. Sori 

 in several roundish or Iransversally oblong patches in rather half-rounded 

 hollows; capsules springing from the veins and parenchyma.

Rhizome short, densely clothed with linear-subulate, entire, bright-reddish- 

 brown scales. Stipes approximate, to 20 c.M. long, erect, blackish, polished 

 like the rachises, scaly at the very base. Fronds + 15 — 20 c.M. each way, 

 3-pinnate with several alternate, erecto-patent lateral branches below the 

 terminal one, the lowest largest, branched again in the lower part. Leaflets 

 + 1 c.M. long, V2~lV2 c.M. broad, obliquely flabellate or suborbicular, 

 stalked, the base cuneate, truncate or rounded, the outer edge rounded, often 

 irregularly and shallowly lobed. Texture papyraceous, firm, subpellucid; sur- 

 faces naked like the rachises and the stipes ; veins terminating in the serratures. 

 Sori 2 — 6 to a leaflet, roundish or Iransversally oblong, placed in indistinct 

 or shallow hollows of the outer edge, the sporangia springing from the 

 veins only.
