POLYPODIACEAE 
CYCLOPHORUS CALVATUS (Baker) C. Christensen, Ind. Fil. 198 (1905). 
Polypodium calvatum Baker, Journ. Bot. (1879) 304. 
Niphobolus calvatus Diels in Engl. Jahrb. 29: 207 (1901). 
Polypodium stigmosum Christ (non Swartz) in Warburg, Monsunia 1: 62 (Ig00). 
Rhizome thick, oblique, rather short-creeping, densely scaly; scales ferruginous, 
spreading, linear-lanceolate, fimbriate; frond caespitose, several together, stipe 5-9 cm 
long, thick, when young densely clothed in loose, long-armed articulated but deciduous 
fine hairs, lamina lanceolate, 20-30 cm long, 2-2.5 cm broad, gradually narrowed 
downward, apex acuminate, margin entire; texture thick coriaceous, color clear light- 
green, pitted above and with a few fine but deciduous stellate hairs, thinly subfurfuraceous 
with gray, wooly, stellate hairs beneath, but becomes perfectly glabrous at last: lateral 
main veins rather distinct in the lower part; sori confined to the upper one-third, 
sparcely intermixed with wooly hairs, rounded, distinct, or sometimes imperfectly fused, 
arranged in 3-5 distinct rows between lateral main veins.

A pretty and distinct fern, with which C. subfurfuraceus (Hook.) from the 
Himalayas is perhaps the only close ally, which differs in much larger dimension, persis- 
tent, thicker, gray wooly hairs on the underside of lamina and in frond of a different 
color.
