Rhizome wide-creeping, thick as a small finger, densely scaly; scales narrowly 
lanceolate, entire, dark-brown, thick; frond 1-3 cm apart, stipe 30-60 cm long, dark 
straminous, naked, deeply grooved above, lamina ovate-deltoid, 30-50 cm each way, 
simple pinnate or bipinnate at base; pinnae generally 1-3-jugate under the terminal one 
similar to the lateral, 14-20 cm long, 3-4 cm broad, broadly lanceolate, petiolate, 
attenuate-cuneate at base, caudate at apex, the basal pair long-petiolate (petiole to 2 cm 
long), generally 2-3-foliolate with the lower one or basal pair of pinnules somewhat 
smaller than the upper or central one; texture thickly chartaceous, margin regularly and 
prickly serrate with deltoid cartilaginous teeth, glabrous above, densely pubescent beneath; 
veins fine, distinct, once or twice forked, veinlets parallel, extending into the serrature, 
each provided with a large prominent brown hydathode at the tip; sori linear, extending 
from costa to near the margin.

This distinct fern, now found to be common in Sikkim-Himalayas and the western

I-3 pairs of pinnae with long-caudate apex, regularly and prickly serrated margin and 
densely pubescent under surface.
