Rhizome thick, creeping, densely scaly; scales rufo-brown, ovate- acuminate ; 
frond approximate, stipe 25-35 cm long, glossy, dark castaneous, lamina deltoid, 
bipinnatifid under the coadunate pinnatifid terminal pinna; lateral pinne 2-4-jugate, 
the basal ones much the largest, shortly petiolate, cordate, deltoid-lanceolate, 10- 
20 cm long, to 12 cm broad, pinnatifid to a narrow wing along costa, the upper 
pinne more or less adnate, also deeply piped with entire, falcate segments, 
of which the lower ones broadly lanceolate, 5-7 em long, about 2 em broad, acumi- 
nate, lobato-incised; lobes falcate, rounded, entire; tewture thin herbaceous, upper- 
side densely pubescent with short, clear, reddish hairs, underside sparcely so, 
margin ciliate, rachis and costa shining castaneous underneath; veins anastomo- 
Sing, areole elongate, mostly without including veinlets; sori rounded, far apart, 
regularly uniseriate on each side of costule of segment, mostly apical on the in- 
cluding veinlets, indusium rotundo-reniform, large, brown, fallen off at last. 
As previously cited, the species is known from Yunnan, Szechwan and 
Kweichow in China, besides Northern India, Siam and Peninsular India. Addi-
