MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 539 
as A. siifoliwm, Mett.; and Mr. Baker has accepted this authority for reducing the 
Peninsula plaut N. Wightii to the Javan A. Teijsmannianum; but the two essentially 
differ: A. Teijsmannianum has the fronds little dimorphic, the fertile pinnze shorter, but 
twice as broad as those of AN Wightii, the lower pinnz with a rounded base, often 
furcate, the margin of the pinne crenate, often sublobed, the sori large, confluent, 
ultimately resembling Meniscium. In short, I regard V. Wightii as abundantly sepa- 
rable (for a Sagenia) from A. siifolium, Mett.—But I am very doubtful about the only 
North-Indian locality, Bhotan. There are several specimens of N. Wightit from Wight’s 
Herbarium ; and it is one of these which is marked as having been got by him from 
Griffith, Bhotan. There is no original ticket of Griffith ; and though Wight got large 
duplicate bundles of Griffith’s Malay collections, I do not know that he got sets of any 
other of Griffith’s plants. 
51. N. pecurrens, Hk. & Baker, Syn. Fil. 299. Rhizome creeping; stipe with many 
linear-subulate brown persistent scales below; frond 1-pinnate; main rhachis 
winged, the wing often decurrent down the stipe; fertile frond often 3 feet; lowest 
pinne 8 in., furcate; barren frond smaller, sometimes undivided palmately 3-lobed.

Mettenius says that his 4. pteropus is not decurrens, Presl; but as he quotes Cuming, ` 
no. 148, it is certain that it is, as Mr. Baker states. The margin of the barren fronds is 
usually quite entire, of the fertile undulate-crenate, which may have puzzled Mettenius, 
who had very scant material. There are placed in the Kew N. decurrens bundle now 
some specimens from Brazil, which are very near, but do not, I think, belong, as the 
sori are not at all regularly biserial. 
52. N. CICUTARIUM, Hk. & Baker, Syn. Fil. 209. Stipes tufted, with many scales close 
tothe bases; main rhachis and primary partial rhachises beneath glabrous or nearly 
s0; frond very thin in texture, nearly glabrous on the surface beneath, 1-2-pinnate, 
sometimes 3-pinnate, deltoid in outline; sori both terminal on a vein terminating 
within looped veins and across the veins; involucres obscurely nephrodioid, some- 
times altogether aspidioid.—. WV. giganteum, Hk. & Baker, Syn. Fil. 299, largely.
