mentioned plants are to be considered as one there is no gain, in beauty at least, 
to CO. rufa, a8 the dubia form is very rough and coarse,—late in the season 
at least: some specimens almost wholly cover my sheets—1 SC EE 
Taking large, whole plants of each species, they are all three distinct ; but 
individual fronds might be culled to match from all three,

: The texture of this fern varies from almost membranous to ceriaceous and 
very heavy. I agree with Mr. Clarke, that it is easily separable from C. rufa 
and C.:albo-marginata ; but he might have gone furthur and have said that 
it has no resemblance to either, beyond being of the same genus, 
. In his “ Summary of New Feres” (Ann. Bot., Vol. V.) Mr. Baker refers to 
the late H. F. Blanford’s paper on “ Silver Ferns of Simla?’ read before the 
Simla Natural History Society, June 25th, 1886, for an account of the Indian 
forms of (. farinosa, and says he cannot separate specifically C. anceps and 
(. grisea therein described as species. But Mr. Blanford modified his views 
afterwards, and in his “ List of the Ferns of Simla,” Journ. Asiatic Soe. 
Bengal, Vol. LVII, Part IL, No. 4, 1888, gave those plants as merely 
varieties of C’. farinosa. 'This is what. he said of the type plant in the latter 
mentioned paper :— 
“This is very abundant in the Siwaliks and Doons, and in the deeper 
valleys of the outer Himalaya up to 4000’, In the neighbourhood 
— of Simla it may be found as hi:h as 5000’, above which I have nob 
met with it. The following characters distinguish i from other allied 
‘forms. Stipes up to 12 ins. long, generally longer than the frond, 
deep red-brown, naked or with a few linear scales near the base only.
