Rhizome short, erect, clothed at the growing tip in dense large brown and broadly ovate, acuminate, 
fimbriate scales; fronds tufted, upright - or spreading and nodding, stipe ‘slender, 8-14 cm long, copiously 
covered with similar spreading scales, fertile lamina Jinear-lanceolate, gradually acuminate, not _ nar- 
rowed towards base, 15-20 cm long, 2.5-3.5 cm broad, pinnatifid at the base almost down to 
the rachis but leaving a broad wing along the rachis upwards; segments numerous, close, patent, oblong- 
ovate, acute, entire, 1.2-14 cm long, 7 mm broad, not auricled in the anterior base, the apical part gradually 
tappering and entire; texture subcoriaceous, dry brown, glabrous above, scaly over the lower side and 
rachis; veins in segments obscure, close, all forked or rarely triforked with very obliquely ascending veinlets 
reaching the margin;-sori medial and uniseriate on each side of costa, exindusiate. The sterile lamina similar 
to the fertile ones, usually less deeply pinnatifid or sometimes simple with wavy margin below, rachis 
lengthening out into a long whip-like: nodding stolon and viviparous at the apex.
