broadest on the upper side at the base ; largest pinnae + 6 cm. long 

 by 2 cm. broad; lowest pinnae somewhat abbreviated. Pinnulae + 7 — 8 

 on a side, obtuse, the lowest + 1 — 1 '/a cm. long by 1 cm. broad, pinnate. 

 Tertiary segments 1 — 2 on a side, cuneate, + 5 mm. long by 2 mm. 

 broad, inciso-dentate on the anterior side. Texture herbaceous; rachises 

 often proliferous in the axils, castaneous, glossy, naked above, scaly beneath, 

 the scales scattered, flbrillose, lanceolate from a hastate-ciliate base ; surfaces

Stipes rather slender, 20 — 45 cm. long, generally flbrillose. Fronds 

 oblong-lanceolate, 25 — 50 cm. long, 2-pinnate in the lower part, the 

 rachis flbrillose, compressed and often proliferous below the apex. Pinnae 

 + 10 — 15 on a side, patent, the lowest + 7'/; — 12 '/2 cm. long by 2 '/j— 4 

 cm. broad, pinnate towards the base, the upper basal pinnule parallel 

 to the main rachis. Pinnulae stalked, ovate-rhomboidal or oblong, 3—5 

 below the pinnatifid upper part, ± 2— 2'/2 cm. long by ± 1 — P,', cm. 

 broad, with a broadly cuneate or abscisso-truncate base, obtuse, bluntly 

 toothed or serrate. Texture chartaceous; upper surface inpresso-striate 

 between the veins; veins oblique. Sori 6 — 7 to a pinnule, reaching costa 

 and margin, those of the pinnatifid portion of the pinnules similar to 

 those of A. pseudofalcatum Hilhbr.

 giabrescent. Fronds 15 — 25 cm. long, 2'/i — S'/j cm. broad, acuminate, 

 2-pinnate. Pinnae stalked, ovate, obtuse. Pinnulae of the largest pinnae

 mm. long and 6 mm. broad, the apex rounded, sUghtly inciso-crenate 

 with obtuse lobes. Texture herbaceous; surfaces naked; rachis castaneous 

 in the lower part, greenish and winged in the upper part, sometimes proliferous 

 in the wing; venation lax. Sori short, not near the margin; indusium 

 broad, pale.
