Plate XXXIII. 
Mr. Clarke’s description is “ Frond large, oblong or ovate-lanceolate, not 
narrowed at the base, 2-3 pinnate ; lowest pinnae often 12 io. 1., falcate ; 
main and partial rhachises nearly free from scales ; tertiary pinnae oblong, 
obtuse, serrate or pinnatifid sometimes nearly to the midrib ; texture, venation, 
and sori nearly as Filix-mas . — Himalaya, alt. 6-9<>00', from Bhotan to 
Kumaun, common in Sikkim ; Khasia, ait. 5000' ; Kohima 6000V , 
Mr. Clarke observes “ This form is called var. elongatum {of N. F.-mas) in 
the Kew bundles, and also by Indian collectors ; but I do noo see that it is 
much like N. elongatum , Hk, & Gr., Ic. Fil. t. 234- {Aspidium % Milde, Fil.Eur. 
1 24), which is founded on a Macaronesian fern that seems to me much more 
like var. KhasiamN In this I quite concur, but I cannot do so in what follows 
the above. N, marginatum , Wall., is quite common as far westward as Simla, 
and even in Western Kashmir, according to Col. MacLeod ; and I have a speci- 
men from the Hazara District collected by Mr. Trotter. I give the habitats I 
have noses of— -as follow: — 
Kashmir : On the range between Jhelam and Kishenganga Valleys— * common 
from 6 to 11,000V’ MacLeod in MS., 1893. 
Punjab : Hazara Dist. — near Dungagali 7000', Trotter No. 546, 189© ; Chamba — 
below Dalhousie 5000', Blanford 1886 ; McDonell ; Kangra Vy. List, — Dharmsala 
6500', Trotter j Simla Region — Simla 5500'-6000', Hope, Blanford, Bliss. 
iV- W. P. : D.D. List. — Mussooree and neighbourhood, from 5000 to 6960', common 
in forest. T. Garh.— Aglar Valley, Dnthie ; Kumaun 47-6000. 
Distrib.— Asia : N. Ind. (Him.), Sikkim (common), Bbotan ; Assam— Khasia 
5000', Kobima 6000' Clef he. 8. Ind., on the Western Mts., 4-6000', Beddome. Ceylon 
(Beddome H. B.). Malay Peninsula— Perak (Beddome Suppt. H. B.> 
The description of N. elongatum, Hk. & Gr., given in the 4 Synapsis ’ under 
N, Filix-mas Kich,, is:— “/r. sometimes 3-4 ft. 1., 2 ft. br., subdeltoid, 
quadripinnatifid ; lower pinnase 1 ft. or more 1., 4-6 in. br., pinnl. dose, 
lanceolate, cut down nearly to the rhachis into oblong orenated lobes ; invoL 
lin.br.;” and the concluding remark, under N. F. -mas, in which is 
included N. elongatum , as var. 7 is— u The extremes as described differ widely, 
but we cannot draw any clear line between them. A. SeUmperianum, canariense , 
Ludomianum , and marginatum , none of them seem clearly separable from 7 
which might be looked for in group 7,” Group 7, when we come to it ten pages 
further on in the ‘ Synopsis / contains 28 species with fronds ample, more than 
1$ — 2 ft. 1., 1. ft. br., decompound. 
Had the description of N. elongatum given in the ‘ Synopsis ’ been simply 
of the Macaronesian plant, as figured in Hooker and Greville’s leones Pilicum, 
the suggestion that the fern mighu be looked for in group 7 of nephrodium 
could hardly have been made. The figure is of the Madeira fern, as gathered
