Rhizome elongate. Stipes 20—30 cm. long, rufo-stramineous, clothed 

 with short and long, grey hairs, as is the rachis. Fronds 50 cm. or more 

 long, + 12 — 15 cm. broad, oblong, acuminate, pinnate, with a large, lobed 

 terminal pinna to + 12 cm. long and S'/j cm. broad. Lateral pinnae 

 sessile, oblong, falcate, to + 10 cm. long and 2 cm. broad, shortly 

 acuminate, broadly and shallowly lobed, the base truncate on the upper 

 side, semicordate and overlapping the rachis on the lower side; lobes + 

 5 mm. broad; lower pinnae rather suddenly reduced to triangular auricles 

 (4—10 on a side. Texture herbaceous; upper surface minutely hairy, 

 lower hairy especially on the costae, costulae and veins, the hairs more 

 or less resembling those of the stipe; veins + 6 on a side, the 3 — 4 

 lower anastomosing, those of the terminal pinna more numerous. Sori 

 4 — 10 on each side of the main veins (costulae), medial, often somewhat 

 oblong; indusium partly persistent partly deciduous, short-hairy. — The 

 description is taken from a duplicate of Elmer's No. 11723.

Stipes 25 cm. or more long, villose, clothed below with narrowly 

 lanceolate, sparingly ciliated scales. Fronds elongate-ovate, + 40 cm. 

 long by 25 cm. or more broad, pinnate. Pinnae 10 or more on each 

 side below the terminal one, subsessile, suberecto-patent, elongate, the 

 apex short-acuminate, subentire, the edge cut '/i ■ '/3-way down to the 

 costa; central pinnae 13 cm. or more long, + 2 '/a l^i^t- broad; 2— 4 lower 

 reduced; 1 — 2 lowest auricle-like. Lobes straight or subfalcate, 3 — 4 mm. 

 ;long by + 4 mm. broad at the base, bluntish. Texture herbaceous; 

 or subcoriaceous ; rachis and costae partly hairy partly strigose; upper 

 surface densely strigose with short, white hairs; under surface glandular 

 and sparingly pilose; veins hirsute with long, white hairs on both sides, 

 10 or more on a side, + 8 — 4 lower anastomosing. Sori subterminal on 

 the veins; capsules short-hairy; indusium provided with a long, white 

 hair. — Rhizome
