540 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
Chota Nagpore, alt. 1000-4000 feet, :common.—Distrib.. South: India, ‚Ceylon, Burma, 
Malaya. Inthe tropics of nearly the whole globe. 
Var. coadunata, Wall. Cat. 877, partly. Frond thick, hairy on the DEEN and often 
on the frond beneath ; involucres nephrodioid.—Hk. & Grev. Ic. Fil. t. 202. Sagenia 
coadunata, Bedd. Ferns South. Ind. t. 81. S. variolosa, Bedd. Ferns Brit. Ind. 
1170. 
As widely spread in North India as the typical NW. cicutarium, and still more plen- 
tiful. So far as the North-Indian examples are concerned, N. coadunatum may be held a 
distinct species; but in the large collections from all parts of the globe I cannot sort as 
between N. cicutarium and N. coadunatum. In North India N. cicutarium is, when 
fairly developed, 2-3 feet across, very thin, light green and glabrous, 2-pinnate, often 
3-pinnate, the pinne often remote; while N. coadunatum is a stout firm thick hairy 
frond on a short stipe, often 1-pinnate, or if 2-pinnate with approximate pinne. 
Wallieh's type sheet of Aspidiwm coadunatum is very glabrous, and is unfortunately 
exactly that variety which has been known in India as not var. coadunata. 
53. N. MULTICAUDATUM, C. B. Clarke. Stipe 1-3 feet, densely clothed nearly its whole 
length with linear-subulate brown persistent scales; frond very large, 2-pinnate, 
3-pinnatifid ; primary lower pinnæ usually 1 foot long; rhachises beneath rusty- 
puberulous, slightly paleaceous.— Aspidium multicaudatum, Wall. in Herb. Sagenia 
silhetensis, C. B. Clarke in Herb. (Pl. LX XVII.) 
Southern base of the Khasi Hills, alt. 0-1000 feet, from Shooshung to Cachar, 
C. B. Clarke.—Distrib. Chappedong. _ 
Much the finest of Indian Sagenias, and easily known by the long densely paleaceous 
stipe: I can see little difference in the venation and sori between this and X. cicutarium, 
var. coadunata. 
30. NEPHROLEPIS, Schott. 
1. N. CORDIFOLIA, Hk. & Baker, Syn. Fil. 300. Rhizome abbreviated, roots often 
bearing tubers ; pinnze numerous, crowded, obtuse or not very acute; ‘sori midway 
between the midriband margin, or sometimes nearer the margin ; involucres horse- 
shoe-shaped.— Luerssen, Fil. Graeff. 198. JV. tuberosa, Presl; Hook. Sp. Fil. iv.

North India, general; alt. 0-5000 feet, from Chumba to Bhotan and SE as 
well as on the hills bordering Hindosthan on the south.—Distrib. South India, Ceylon, 
Burma, Malaya ; the tropics of the whole world, extending to New Zealand, Japan.
