532 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. ` 
example is pasted down on the same sheet as Blume’s, without any original ticket. 
This marked fern may have been accidentally issued by Blume as his JY. glandulosum ; 
if so, it might be renamed JV. meniscioides. 
Var. lete-strigosa (Pl. LXXIV. fig. 2). Fronds 2-4 feet; pinne pinnatifid 3 the way 
to the midrib ; involucres firm, nephrodioid, glabrous, sori not confluent. ` 
Sylhet, Griffith. Chittagong Hills, alt. 0-500 feet, abundant, C. B. Clarke.—This 
differs from JV. pennigerum, Hk., by the frond being strigose above, abrupt at the base. 
37. N. PENNIGERUM, Hook. Sp. Fil. iv. 72. Stipe villous; frond large; lowest pinnæ 
reduced distant sometimes to auricles; pinnæ cut 1—3 the way down to the midrib; 
lobes ovate, subacute, hardly toothed, 2-8 pairs of veinlets uniting; rhachis and 
under surface villous; involucres subpersistent.—Hk. & Baker, Syn. Fil. 292.

Ceylon, Malay Peninsula and Islands, Tropical Africa. 
. Var. multilineata, Wall. Cat. 353. Main rhachis and veinlets beneath puberulous, 
minutely pubescent or glabrous; frond otherwise glabrous. 
East Bengal from Mishmee (Griffith) to Chittagong, where it is plentiful, alt. 200- 
1000 feet.—Distrib. Malay Peninsula. 
98. N. AMBOINENSE, Presl; Hook. Sp. Fil. iv. 75. Stipe and main rhachis beneath 
nearly naked; frond somewhat reduced at the base, but scarcely tapering; pinnse 
subentire or cut 3 the way down to the midrib into close oblong subfaleate lobes, 
several pair of veinlets uniting, minutely hairy beneath or glabrous; involucre 
glabrous, deciduous.—Hk. & Baker, Syn. Fil. 292. VN. extensum, var. B. minor,

Bengal and Assam, near the foot of the hills, common.—Distrib. South India, Ceylon, 
Burma, Malaya, Tropical Asia, Africa, and America. 
This fern is that portion of JV. parasiticum that has the pinnz cut down less than 4 the 
way to the midrib. The separation of the two species is artificial. I altogether doubt 
their distinctness. It is impossible to state the area of JV. amboinense with any accuracy, — 
as a considerable number of the specimens are quite uncertainly referred to it, and may [e 
be N. parasiticum.—As to N. latipinna, if separable as the most trifling var. of W. am- 
boinense, it grows in Chittagong. My examples and the Hongkong typical are. identical. 
X Arbuscula, Desv., is said by Col. Beddome to be ** general ” in India. | There are no 
exa mples of typical N. Arbuscula from North India; there are placed i in the Kew N. Ar-
