Rhizome short. Stipes aggregate, about 40—60 cm. long, stram- 

 ineous or pale-brown, provided in the lower part with scattered, subu- 

 late-lanceolate, sparingly eroso-denticulate or subentire, fuscous scales, 

 the rest naked, as is the rachis. Fronds about 25 — 50 cm. long, pinnate, 

 the barren fronds the largest. Barren fronds with the pinnae simple, 

 much acuminated, entire to subrepand or subsinuate; terminal pinna 

 lanceolate-oblong, 25 — 30 cm. long, 10 — 12 cm. broad, cuneate at the 

 base; lateral pinnae 1 — 6 on a side, ascending, opposite, lanceolate, 

 straight or subfalcate, 20 — 30 cm. long by 3 — 10 cm. broad, the highest 

 adnate and suddenly decurrent at the base, free or connected with the 

 terminal one, the lowest the largest, shortly petiolate. Texture coriaceous ; 

 surfaces naked ; main veins oblique, straight or more commonly upcurved, 

 connected by nearly straight transversal veins so as to form numerous 

 subquadrangular primary areolae; secondary areolae irregular, with free 

 included veinlets. Fertile fronds with the pinnae about Vj — ^U as large 

 as in the barren fronds, with the areolae nearly square with solitary 

 escurrent free veinlets Sori large, numerous, in 2 rows between the 

 main veins, terminal on the free veinlets, suboblong ; indusium persistent.

Stipes naked, castaneous. Fronds deltoid, + 30 — 45 cm. each way, 

 3-pinnatifld. Lower pinnae largest, deltoid, unequal-sided, with large 

 lanceolate pinnulae, the lowest deeply lobed. Texture moderately firm; 

 surfaces bright-green, densely pubescent on the ribs; rachises castaneous, 

 pubescent; areolae fine, with copious included free veinlets. Sori largej 

 uniserial near the main veins; indusium minute, fugacious. — A duplicate
