THE FERNS OF NORTH-WESTERN INDIA. 633 



ifc applied to the distance between the pinnae or to the distance between 

 the fronds ; but, as Don does not mention the venation, and says — 

 " pinnis distantibus" I think it may be concluded that the name refers to the 

 pinnae. Whether the present fern ought to be called P. paliulosum, or by one 

 of Wallich's three or four names, is a point that perhaps may never be settled ; 

 but that it is distinct from P. distans, Don, cannot, I think, be questioned. 

 In the difficulty Wallich created by not attending to the nature of the rhizome, 

 and by giving so many names to his specimens, it seems advisable 

 to give a new name to those that caunot reasonably be put under 

 P. distans.
