margin; indusium membranaceous, persistent. — The young plants have 

 the fronds much smaller, wibh the pinnae short, membranaceous, resembling 

 in aspect those of A. tenerum Forst. or A. Belangeri Kze.

Near A. stenochlaenoides v. A. v. R. — Stipes not articulated at the 

 base, green or stramineous; fronds of young plants laxly and deeply 3- 

 pinnatifld with linear-oblong or narrow-cuneate, subacute or emarginate 

 tertiary segments. Fertile fronds unknown. — Resembles somewhat A. 

 Wightianum Wall, which, however, has the pinnae equal-sided at the base.

Rhizome short, the scales Unear-subulate, dark-brown. Stipes approx 

 imate, 5 — 20 cm. long, ohvaceous when dry, rather naked, very narrowly 

 winged. Fronds simple or 3-foliate, or probably pinnate in the fully 

 developed plant; simple fronds lanceolate or oblanceolate, 15 — 25 cm. 

 long, 2—3 cm. broad, the apes more or less suddenly acuminate, the 

 edge very shallowly but rather broadly crenulate, bounded by a pellucid 

 strand, the base gradually decurrent; 3-foliate fronds with the terminal 

 pinna similar to the simple fronds, the lateral pinnae sessile, rather erecto- 

 patent, shorter than the terminal one, the upper base narrowly rounded, 

 the lower base cuneate, suddenly decurrent upon the stipe. Texture 

 herbaceous; surfaces ohvaceous when dry, under surface sparingly and 

 very minutely scaly, the scales brown, fimbriate-stellate ; veins subspread- 

 ing, fine, simple or forked. Sori occupying the lower '/2 — 'U ^^ ^^^ 

 veins, not reaching the costa; indusium pale-olivaceous-brown.

Pinnae remote, tough-herbaceous or flaccid-coriaceous, unequally and 

 rather abruptly rotundate-cuneate at the base, subserrate or broadly 

 crenulate, to 3'/a cm. broad. — The terminal pinna and the one next 

 below it are very close together and almost of the same size, giving the 

 frond a peculiar appearance of truncateness.
