Woodsia Veitchit Christ, Bull. Acad. Géogr. Bot. (1906) 121; C. Chr. Ind. Fil. Suppl. I. 74 (1912). 
Rhizome short, erect or oblique, densely scaly; scales broadly lanceolate, finely 
acuminate, denticulate, atro-brown or castaneous; fryonds caespitose, stipe to 14 cm long, 
soft; dark-straminous below with lax lanceolate smaller scales, lamina to 20 cm long, 8 
cm broad at base, oblong-lanceolate, acuminate, base hardly narrowed, truncate, 
subbipinnate; pinnae 6-10-jugate, patent, short-petiolate, oblong-lanceolate, acuminate, to 
4 cm long. 2 cm ‘broad at truncate-cordate base, pinnate; pinmnules to 10-jugate, 
sessile or more or less adnate, patent, ovate-oblong; rounded, base truncate, to I cm 
long, 6 mm broad, pinnatifid half-way down with 3-4-jugate, rounded, sharply dentate 
teeth; texture thin, soft, becoming hyaline towards margin, rachis and costa of pinnae 
fibrillose-scaly, otherwise glabrous; veins very distinct, pinnate in ultimate segments, one 
to each tooth, but not reaching the tip; sov7 rather small, rounded, one-rowed and nearer 
to costa of pinnule than margin, borne on the lower middle of anterior basal veinlet of 
each ultimate segment, indusium fairly large, rounded, deeply notched, gray, membra- 
naceous, with fimbriate margin.

Himalayas, Sikkim and Bothan; also Formosa Island; very common in Sikkim. 
A distinct rather little fern of the genus, characterized by, above all, spinulose- 
dentate serrature and gray membranaceous indusium with rather long-fimbriate margin.
