This is A. ocellatum , Wall. Cat. 360, in Herb. 1823, “ Napalia 1820.’ 5 
D. Don's name was the first published, but his description was written from 
Wallioh's* specimens collected “ in Napalise alpibus.” It is also Hooker’s A, 
auriculatum , var. subbipinmta , Sp. Fil., Vol. IV., p. 11 . It is strange that 
neither Don nor Hooker mention the chief distinguishing character of this 
species, which is indicated by the specific name given tc it by ( ? ) namely, 
radicans . Clarke says— 1 ‘‘ This fern frequently produces a subfcerminel rooting 
bud on the main rhachis ; then it is called Polystichum radicans” but neither 
Baker nor Beddome mentions this character ; though it pertains to every 
plant I have seen, though not to every frond, and neither A. auriculatum , 
nor its other so-called varieties — A , marginatum , Walk and A. obliquum , Don — 
ever have it, so far as I km>w. I have a frond from Tehri Garhwal, which has 
not only a young plant with four pinnated and Poriferous fronds growing from 
its apex, but also another growing pi mt on the lowest pinna) of all, mar its 
apex. The buds and young apical plants are densely clothed with pale brown 
scales. The cutting of A. lentum varies a good deal\bdt I think it is always 
deeper than that of A. auriculatum. , and of the simple form of A marginatum , 
and is from one to two-thirds downwards to the midrib, except in Struck ey 
and Winterbottom’s Kipnaun specimens which, though proliferous, have nearly 
entire pinnae. The Ipbes^are obliquely rounded and 'pointed, with generally only 
one aristate tooth to each. The veins are pinnate in the lobes, two to five 
veinlets in a lobe, one or more of which forks. The sort are email, and 
uniserial, placed on the inferior veinlet of each group, about half- Way between 
costa and margin, and the sometimes quite free falcate auricled segment next
