bristle-like scales. Stipes dense, ± 17 — 18 c.M. long, ebeneous and glossy 

 like the rachis. Fronds + 45 c.M. long, linear, simply pinnate, proliferous, 

 narrowed gradually towards the apex. Leaflets subsessile, spreading, to 2 c.M. 

 long, 5 — 8 m.M. broad, the upper base obliquely truncate or cuneate, the 

 outer edge obtuse. Lobes ovate or transversally oblong, the lower ones 2-fid, 

 the barren ones obtusely denticulate, the fertile ones retuse. Texture rigidly 

 chartaceous ; rachis hairy above ; veins prominent, strigose. Sori solitary on 

 the lobes; indusium coriaceous, transversally oblong.

Rhizome short-creeping or erect, clothed with brown, lanceolate scales. 

 Stipes tufted or approximate, 5 — 15 c.M. long, wiry, dark-brown, clothed with 

 a brown tomentum. Fronds simply pinnate, 15 — 30 c.M. long, the apex 

 often nudate, elongate, caudate, rooting at the point. Leaflets dimidiate, + 

 sessile with a cuneate base, 1 — 2 c.M. long, half as broad, the lower edge 

 straight and entire, the upper and outer more or less broadly cut, often deeply 

 and repeatedly, the outer edge bluntly rounded, lowest leaflets not rarely sub- 

 flabellate. Lobes linear-oblong or oblong, with the apex rounded or truncate, 

 entire or serrulate. Texture coriaceous; rachis and surfaces more or less 

 densely pilose. Sori roundish or transversally oblong, terminal on the lobes; 

 sporangia springing from the veins only.

Near A. caudatum, L. Fronds elongate-lanceolate, simply pinnate, often 

 tapering into a long rooting and proliferous apex bare of pinnae. Leaflets 

 alternate, short-stalked, semiovate, the upper base truncate, parallel to the 

 rachis, the upper edge lobed, the lobes retuse, soriferous, shining above. 

 Texture chartaceo-coriaceous ; rachis ebeneous or reddish-brown like the slightly 

 chafl'y stipe, naked, glossy; surfaces + naked; veins numerous, compact, fine. 

 Indusium obreniform, thick, coriaceous.
