Rhizome thick, short, woody, erect, scales dense, imbricate, linear-lanceolate to 

 linear-subulate, 1. 5-2 cm. long, with long hair-pointed frizzy apices, often 2-cleft, 

 blackish, ciliate; stipes strong, 50-85 cm. long, about 1 cm. thick, dark brown, and 

 paleaceous near the base, greenish upward, turning dark stramineous upon drying, 

 broadly channelled above, scales similar to the rhizomatic ones, sparse on the basal 

 part of the stipe, glabrous upward; fronds ample, 40-60 cm. long, 20-26 cm. broad, 

 simply pinnate, broadly oblong, slightly abbreviate towards base, glabrous on both 

 surfaces; texture herbaceous, moderately firm, glossy green above, paler below (when 

 living); pinnae 7-9 on each side below a broad and shallowly pinnatifid acuminate 

 apex, 2-3 cm. apart, oblong-lanceolate, petiolate (petiole 5 mm. long), the uppermost 

 ones adnate, 17-19 cm. long, 3-4 cm. broad, base sub truncate to subrotund, apex 

 acuminate, margin remotely lobato-crenate into broad rounded short lobes; midrib 

 prominent, lateral veins spreading about 7 mm. apart, veinlets 5-6-jugate, free, very
