KNUMERATIO FILICUM PHII.IPPINAHUM, 393 



tion from the islands of Java, Celebes, &c., presented to me 

 by Professor Reinwardt of Leyden, many of which are iden- 

 tical with Mr Cuming's; and on looking at the labours of 

 Horsfield, Reinwardt, and Blume, in these Islands, and Haenke 

 in the Philippines, &c., we need not be surprised to find the 

 greater part already known; and it is even highly probable 

 that some which I have now given as new species, may, on 

 further examination, and reference to specimens, prove to be 

 previously described. Nevertheless, I trust the following 

 enumeration will be found useful, and serve as a key to those 

 who may be inclined to assist in clearing up any doubtful 

 species. 



The arrangement adopted is the same as given by me in a 

 paper on the " genera of Ferns," which was read last year 

 before the Linnean Society, and which in principle agrees 

 with that of Presl, but differing on points as regards the value 

 of characters and affinities and extent of some genera. 



In the collection there are a few o;eneric forms which I was 

 not before sufficiently acquainted with, to warrant their adop- 

 tion in my original paper; and in order that the following 

 should be confined to a list of names, I have refrained from 

 giving the characters of the new forms, as I intend to treat of 

 them more at length in a separate paper, as an addendum to 

 my original article. I have therefore only made a few ob- 

 servations on the new forms, as also on the peculiarities of a 

 few of the species, brought about by difference of age and 

 place of growth, and which, in my opinion, are not suffici- 

 ently attended to by many botanists.
