Rhizome 4-6 mm thick, wide-creeping, densely clothed in bright brown linear- 
lanceolate scales to 3 cm long; frond approximate, stipe 10-25 cm long, straminous, 
densely clothed at the swollen base in a cushion of golden brown scales similar to 
those on rhizome, glabrous upwards, deeply grooved and hirsute above, lamina 
deltcid-pentagonous, 10-25 cm long and broad, 4-pinnatifid; Bi 5-10-jugate, the 
basal ones much the largest, petiolate; pinnules of 2nd. order oblong, bluntish, base 
rotundo-cuneate, equal, decurrent above the middle, deeply pinnatifid into oblong, 
rounded lobato-serrate segments with roundish apex; texture herbaceous, both sides 
densely setose hairy; veins distinct, free, pinnate in segment; sori large, rounded,
