TIT. 154 (1934) 
Rhizome wide-creeping, densely scaly; scales fusco-brown, linear-lanceolate from 
ovate base, clathrate, entire; frond far apart, subdimorhpous, the fertile one with stipe to 
20 cm long. straminous, glabrous, lamina 20-24 cm long, to 8 cm broad, oblong-elongate, 
with caudate apex, simple pinnate; pinnae to 16 pairs, subopposite, obliquely patent, to 5 
cm long, 7 mm broad, basal ones not shortened, gradually abbreviated towards the 
caudate apex, narrowly lanceolate, acuminate, entire, considerably constricted above 
decurrent base, the upper ones are connected by a narrow wing along rachis; texture her- 
baceous, green, glabrous on both sides; veins anastomosing only in two rows of oblique 
areole along costa; sori linear, oblique, extending from near the costa to margin; sterile 
fronds conform but much shorter, on stipe 10 cm long, lamina 15 cm long, to 7 cm broad;
