Rhizome short, erect, densely radicose; scales at the apex dark brown, lan- 
ceolate-subulate, rigid, extending upward to some distance above the base of 
stipe; fronds ceespitose, stipe castaneous, terete throughout, 7-20 cm long, lamina 
pentagcnous or subdeltoid, 7-14 cm long and broad, tripinnate or tripinnatifid ; 
pinne 5-7-jugate, the lower cnes petiolate, far apart, opposite, the basal ones 
much the largest, deltoid, 5-12 em long; pinnules 5-7-jugate, the lower basal one 
much the largest and basicopically produced, 3-6 cm long, shorily petiolulate, 
the upper ones on the same side of costa sessile and adnate, gradually shortened, 
those on the upperside of costa are of about equal length, sessile, adnate, and 
much shorter than those below, alternate; ultimate pinnules oblong, blunt, lobato- 
incised with rounded lobes, or only crenate in small plants: rachis and rachilets 
deeply grooved above; texture herbaceous, veins distinct, 2-3-forked or simple to- 
wards apex in lobes; sori terminating the veinlets, distinct at first, finally sub- 
confluent, indusiwm membranaceous, oblong-ovate, distinct or subcontinuous ; 
spores bilateral, light brown.

This distinct and endemic species belongs to the group of Ch. tenuifolia Sw. 
from which it differs altogether in the rigid, dark-brown lanceolate scales on 
rhizome, less divided lamina of a pentagonous outline, with ultimate segments of 
entirely different shape. All Specimens cited above are very uniformly constant 
in all respects except size, in which the type represents a large form with penta- 
gonous lamina and acuminate apex, on Stipe twice as long; while Ch. Wilsoni and 
Ch. taliensis represent small, stunted form with less divided fronds.
