Cyrtomium viltatum Christ ex Léveille, Bull. Acad. Géogr. Bot. (r9r0, non 1905). 
Rhizome short, oblique or erect, densely scaly; scales large, 1 cm or longer, 
rufo-brown or atro-castaneous, glossy, ovate, acuminate; fronds cespitose, stipe 
15-30 cm long, strong, densely clothed in the similar scales, which are mixed with 
others of linear outline, lamina oblong, 15-45 cm long, 10-17 cm broad, pinnate under 
the free hastate end-pinna; pinnz 10-20-jugate, alternate, lower ones hardly short- 
ened, in typical form, up to 10 cm long, 2 cm broad, falcate, long-acuminate, shortly 
petiolate, base broadened, rounded or auricled above, margin finely serrate through- 
out; texture chartaceous, light green, not glossy in living state, rachis fibrillose- 
scaly throughout; veins distinct, copiously reticulated, areole hexagonal, oblique, 
each with 1-2 excurrent included soriferous veinlets; sori rounded, scattered over 
the underside, terminal or infra-apical on the veinlets, indusium large, coriaceous, 
grayish, rounded, peltately attached, depressed at centre, with wavy margin. 
This is one of the most common ferns throughout the Yangtze valley and 
extends as far north as the southern part of Shensi and southwardly to the north 
of Canton (Lokchong, W. 7’. Tsang 20706). Also Japan and southern Corea; recent- 
ly known from Tonkin. 
A very distinct but very variable fern, generally regarded hitherto as a 
variety of C. falcatum, from which it can be easily told apart by its much thinner 
leaves of a light green color, not glossy, in living state, its generally more numer- 
ous, lanceolate-falcate or sometimes oblong-ovate (as in var. polypterum) pinne 
always with minutely and regularly serrate margin from the base upwards. Gen- 
erally grown as pot plant.
