as an Indian fern, though a rare one. I have since found other Indian 
specimens of the typical plant at Kew. Most of the seven varieties which 
Clarke adopted or set up have already been upset or reduced to other species of 
Athyrium , and his var. 1, dentigera (Polypodium dentigemm , Wall. Cat. 334), 
I cannot distinctly separate from the type, the only real differences being in 
the shape of the pinnules, which are more equal-sided and less pointed than are 
those of the type, and in the cutting of the segments, which in dentigemm are 
always sharply toothed. I have seen the latter plant growing in the Simla 
Region, and at first I thought it was distinct ; but I had no living specimens 
of the type with which to compare it. The type plant has not yet been found 
in the Simla Region by me or by any other collector in recent times ; though 
there is a specimen of Dr. Thomson’s in Kew marked as from Hattu Mountain. 
Without taking into account sports and cultural varieties, there is so much 
variation in individuals of A. Filix-jemim found in Europe, that I could not 
expect European pteridologists to agree with me were I to separate A. dentigemm ; 
but the fact remains that it is the common Himalayan plant, and that it does 
not vary, except in size. The smaller, and sometimes narrower-fronded, plants 
are Clarke’s var. attenuata of the type.

I quote Colonel Beddome’s description 
“ Athyrium Duthiei Bedd. Rhizome wide-creeping, black, nearly naked ; 
stipe 3— 4 in. long, furnished with a few ovate or lanceolate 
deciduous scales, glabrous, pinkish ; fronds narrow, ovate-lanceolate, 
about 12 in. long by 3 — 4 in. broad ; pinnse lanceolate, alternate, 
about 20 on each side ; lower ones gradually reduced, the central 
ones \\ — 2 in. long, f in. broad, pinnatified nearly or quite 
to the rhachis into sharply-toothed obovate or lanceolate lobes 
about two lines broad ; texture herbaceous ; rhachises glabrous, 
pinkish, furnished with a few deciduous large lanceolate scales ; 
both surfaces glabrous ; veinlets forked ; sori asplenioid or hippo- 
crepiform, 6—8 to each pinnule or lobe, i. e., 3 — 4 on each side 
on the lower veinlets midway between the edge and the midrib.
