of the peculiar position of the pinnae mentioned by Jenman, which 

 makes it necessary to twist them around in order to have them lie 

 in a plane with the rachis.

of this species- 



The Devonshire marsh, where it grows, lies in the central valley 

 of the large center island known as "the Mainland/ 1 and is out of 

 the reach of tide water. The plants strike every one who sees 

 them as being magnificent in size, reaching far above the head of 

 any man, sometimes to the height of eight or nine feet Mr. Jenman 

 says: "This is the plant figured in Eat. Ferns N. Am. for A. 

 aiireitm, though the true aureian is also found in Florida. It (A 

 lomarioides) ranges from Florida and the Bahamas down through 

 the West Indies and Guianas to the Brazils." This, therefore, adds 

 another species to the ferns of our own country. Eaton figures 

 only the fertile frond, but shows a section of a pinna with the spo- 

 rangia removed, thus disclosing the venation. This is represented 

 as running rather more oblique to the rachis than it does in A. 

 lomarioides, but in other respects the figure is very good. It is 

 taken from an Indian River specimen, where, Eaton tells us, the 

 fronds grow very tall and have all the pinnae of the fertile frond 

 fertile and closely appressed to the rachis ; which is a correct, con- 

 densed description of A. lomarioides.

In addition to the above named species, Governor Lefroy put 

 at the end of his list Blechnum occidental L. which, he said, " was 

 planted out in suitable places in 1877." Neither Hemsley nor 

 Reade seems to have had any native specimen of it, nor is there 

 any evidence of its existence there now. It must therefore be 

 regarded as another case of failure to become naturalized. 



If we eliminate from this list the species Dryopteris mollis, 

 which was evidently catalogued through- some mistake, there 

 will remain 25 species and varieties of ferns that may properly be 

 regarded as native or naturalized in Bermuda. An analysis of
