Rhizome short, erect, densely scaly; scales rufo-brown, lanceolate-subulate ; 
fronds tufted, stipe 2-5 cm long, dark castaneous, shining, terete with a channel 
above, densely scaly throughout, lamina lanceolate, 8-20 cm long or longer, 1.5-6 
cm broad, shortly acuminate, sub-bipinnatifid; pinnx 10-15-jugate, subsessile, the 
lower ones more or less shortened, the middle ones 1.4 cm long, or longer, 0.5-2 
cm broad, oblong-deltoid, acute or obtusish, pinnatifid nearly down to costa into 
4-6 oblong, crenate or erosed segments, with 2-4 oblique and simple veinlets to 
each tooth, rachis more or less scaly, castaneous, costa of the same color under- 
neath, both sides glabrous; texture herbaceous, greenish; sov7 globose, distinct on 
each crena with the reflexed margin of an oblong shape as indusium. 
Numerous specimens have been seen from Chekiang (including type, leg. 
Alexander in Chusan Island), Kwangtung (including type of Ch. Fordii), Fukien, 
Kwangsi, Kiangsi, Hupeh, Kweichow, Szechwan (including type of Ch. Bockii, 
leg. Rosthorn 1766 in Nanchuan) and Kiangsu. A complete enumeration of the 
Specimens from the above localities will be given later in my ‘‘Studies of Chinese 
Ferns,”’ 
Specimens from Japan (Nagasaki, leg. Maximowicz 25), Tonkin (Balansa 
129), Formosa and Luzon are also examined. 
The present fern, now found to be very common in Eastern, Southern and 
Central China and Japan, has generally been considered as identical with Ch. 
mysuriensis Wall. of East India from which it differs in characters as already noted 
in my previous paper (Cf. Bull. Dept. Biol. Sun Yatsen Univ. No. 6: p. 26).
