Colombo, December, 1880. 
The M.S. of the Ferns proper of this list was finished on the 15th 
October, 1873, and was printed off as far as No. 153 before May 1875.— 
From a Supplement by Col. Beddome to his Ferns of Southern India and 
British India published in 1876, I have inserted some additional numbers 
discovered in Ceylon, and made a few corrections. In a paper on the Ferns 
of Northern India, by Mr. C. B. Clarke, published in vol. 1, 2nd series, of 
the Linnean Society’s transactions, in 1880, he has fully discussed several of 
those about which I had previously written, confirming my views in many 
instances. From this paper and a check list of Ceylon ferns, by 
George Wall, Esq., I now add the following names which differ from those 
in my list. Mr. Clarke gives some ferns as Ceylon ones which I do not 
believe have been found in the island. Mr. Clarke’s elaborate paper, which 
is intended as a supplement to the Synopsis Filicum of Hooker and Baker, 
proves what a vexed question the proper names of ferns has become in 
many cases, and also that there is no danger of the subject being exhausted. 
In transferring this list .of altered names, I do not mean that all Mr. Clarke’s 
alterations should be adopted as correct.

with the following note on it : — Fronds cordate without marginal 
rim, and spurious venules, not T. muscoides. Trichomanes Motley i,

where, remarked : — Different from T. Motleyi in having setaceous 
margin, and the fruit not in a sinus.
