POSTSCRIPT 
Since the foregoing pages were printed, Mr. Baker has kindly informed me of the following revisions of our 
Ceylon ferns for the second edition of the Synopsis now in preparation. 
Davallia Trichomanoides, Bl.—There has been some uncertainty about the original type of this species, but it is 
now identified, and our Ceylon species is found to be very distinct. It is named Dav. Schizophylla, Baker. 
Asplenium Persicifolium, J. Sm.—Our Ceylon species is A. Zenkerianum of Kunze, and is now regarded as 
distinct from the typical form of the Phillipine-Island original, differing therefrom in its shorter son, entire 
edge and less woody stipes. 
Asplenium Japonicum, Thunb.—The Japanese type of this species resembles very closely our Aspl. Thwaitesii, 
insomuch that the only present representative of the species at Kew from Ceylon was sent by Dr. Thwaites 
as a “large form” of Thivaitesii, and with the same C.P. number, 1343. This number therefore represents 
both species in part, if, in fact, the two are really distinct. C.P. 3951, mentioned in the list of Dr. Thwaites’ 
addenda, page 11, as Aspl. Decussatum, Wallich, and hitherto referred to A. Japonicum, is a good species, 
differing from Japonicum chiefly in having an erect caudex. As there is already an Aspl. Decussatum, 
however, Mr. Baker gives the Ceylon species the name of A. Polyrliizon, owing to its dense mass of why 
roots. This is the species figured by Beddome in plate 292 of his ‘ Ferns of Southern India.’ 
Another Ceylon species included under Japonicum in the first edition of the Synopsis, will appear 
in the second as A. Schkulirii, Thwaites. This plant has also an upright caudex. Its C.P. number is 
3100, and it is figured in Beddome’s * Ferns of Southern India,’ plate 230. To me this seems to run too 
close to some foims of the very variable species Dipl. Decurrens of Beddome, which = A. Maximum, Don. 
Polypodium Parasiticum, Mett.—The fern mentioned in the note at page 7 will appear as Pol. Mediate, 
Mr. Baker having decided, after a careful inspection of all my specimens, that it cannot be safely included 
under P. Australe, owing to the situation of the sori being farther from the midrib than in that species. 
Polypodium Lingua, Sw. —Dr. Kuhn describes our plant as a new species under the name of Pol. Pannosum, Mett. 
(Linnsea, vol. xxxvi. p. 141), which is distinguished from the typical Lingua of Japan by its sori, which fall 
(sometimes considerably) short of the edge of the frond. Its vestiture, which has no doubt suggested its 
name, is also closer and finer than in Lingua. Mettenius and Kuhn separate the Himalayan Lingua as a 
third species, under the name of Heteractis. 
Acrostichum Spathulatum, Bory.—The note at page 8 was written under the impression that Mr. Baker 
admitted the new species A. Acutum as distinct, but that is not his opinion, and our species remains in the 
Catalogue as before. 
These revisions cause the following changes in the foregoing Catalogue, viz .:— 
Davallia Schizophylla, Baker, vice D. Trichomanoides, Hk. 
Asplenium Zenkerianum, Kunze, vice A. Persicifolium, J. Sm. 
Additional species:— 
Asplenium Polyrhizon, Baker. 
Asplenium Schkuhrii, Thwaites. 
Polypodium Mediale, Baker. 
All peculiar to Ceylon.
