Rhizome thick, woody, oblique or erect, densely scaly; scales bright ferruginous- 
brown, to I cm long, broadly lanceolate, long-acuminate, membranceous, fimbriate, mixed 
with smaller linear ones; fronds caespitose, stipe 20-35 cm long, stout, rufo-straminous, 
densely clothed throughout in similar but somewhat smaller spreading curled scales, 
which extend upward over entire rachis and base of pinnae beneath, lamina oblong-ovate, 
35-60 cm long, 17-25 cm broad, acuminate, base not narrowed, bipinnate; pinnae 8-14- 
jugate, 10-20 cm long, 3-4 cm broad, linear-lanceolate, acuminate, subpatent, basal ones 
opposite, upper ones subopposite, 5-6 cm apart, short-petiolate, base truncate, slightly 
cordate, fully pinnate under deeply pinnatifid apical part; pinnules 14-18-jugate, 1.5-3.5 
cm long, 5-I0 mm broad, deltoid-oblong, subopposite, sessile, obtuse with auriculately 
broadened base on both sides, basal ones in the basal pinnae rarely any longer than neigh- 
bouring ones, subentire, or crenate-serrate or, in large forms, lobato-pinnatifid half-way 
down into 4-6 pairs of oblong truncate lobes under serrate acuminate apex; texture 
coriaceous, light green, glabrous above, rather copiously fibrillose-scaly on costa of pinnae 
beneath, stipe and rachis moderately muricate by the persistent base of fallen scales; 
venation obscure, veins in pinnules or lobes pinnate; sori rounded, medium-sized, brown, 
one-rowed midway between costa and margin or often much nearer to the margin, dorsal 
on the anterior basal veinlet of each group; indusium rotundo-reniform, notched, brown, 
subcoriaceous and fallen off at last.

This distinct fern, now found to be very common in the eastern and south-eastern 
parts of China, resembles in general habit D. erythrosora (Eaton) with which it has 
hitherto been considered as identical and from which, however, it can always be distin- 
guished by, above all, the characteristically golden brown, spreading, broadly lanceolate, 
fimbriate, curled, dense large scales from base of stipe upwards throughout the entire 
length of rachis and the underside of costa, by somewhat oblong-deltoid falcate pinnules 
with auriculately broadened base and thicker texture.
