this species is Blume's plant. A few weeks ago a large num- 

 ber of very nice living specimens were gathered in West-Java 

 and transplanted in the Botanic Gardens, where they do very 

 well, so I had the best occasion to study it. 



Sir W. J. Hooker regarded this fern as being an abnormal 

 form of Polypodium lomarioides Knze and so does Mr. Baker, 

 but on various reasons I believe the species is a distinct one. 

 Not only the rhizome is very different from that of P. loma- 

 rioides and P. sinuosum and wholy destitute of scales , but the 

 venation too is quite distinct by its large costal areoles as can 

 be seen in comparing the figures on Plate VII where a part 

 of the fertile pinnae of both specimens and a part of the ste- 

 rile pinna of the above mentioned is represented. Besides this 

 the colour of the caudex and the frond , the texture , which is 

 by no means coriaceous, the peculiar place of the sori and the 

 circumstance that the same form has been gathered in very 

 different parts of our Archipelago (I possess specimens from 

 Java, Celebes and Borneo, Mr. Blume's specimens being gathe- 

 red in the Moluccae) may prove this. However there is no 

 reasou , why to place the plants in question in a distinct genus 

 as Mr. Blume did ; undoubtedly it is allied to Polypodium loma- 

 rioides and must be placed near that species. 



I cannot help thinking Mr. Cesati's Davallia (Microlepia) de- 

 parioides, Felci pag. 13 fig. 4) must be the same plant. In 

 general outline and peculiar caudex and in various other res- 

 pects it resembles it so very much that if not Mr. Cesati as- 

 sured that the sori were indusiate when young I should think 

 it was the same species.
