arrangement. The older and better known names are re- 
stored to many of the plants; and though no single work is 
followed in this respect, the nomenclature is generally the 
same as that of the British Flora. The general list includes 
only native and naturalized plants; the latter being distin- 
guished by a different type. A separate list is appended, 
including upwards of a hundred “excluded species," being 
those * not recently found in the localities indicated for 
them, erroneously introduced into lists of native plants, or 
not sufficiently naturalized.” 
Differences of opinion will doubtless be entertained about 
the correct allocation of certain plants among the native, the 
naturalized, or the excluded; but there is an obvious conve- 
nience in making such distinctions. Still more diversity of 
Opinion may be anticipated in regard to the limits drawn 
between species and varieties; many appearing only as va- 
rieties in the London Catalogue, which have been described 
as species by authors. Here the discrepancies between the 
Catalogues of the two Societies, those of Edinburgh and 
London, are very wide. The species of the Edinburgh 
Catalogue exceed those of the London Catalogue by one 
hundred and ten; but as a set-off against this, we find the 
latter enumerating nearly five hundred named varieties, more 
than double the number of varieties included in the Edin- 
mentioned, it rises much higher in our esteem on account of the candour 
With which he speaks of his predecessor in the same line ; and it detracts 
nothing from Mr, Smith's merit that Presl was his predecessor in these 
!nnovations, for the two writers worked wholly independently of each 
other, “I had nearly," says Mr. J. Smith, “completed my arrange- 
ment, when I received a copy of Presl’s “Tentamen Pteridographie,’ a 
Work. published at Prague in 1836, but not seen by me till 1838. That 
author’s opinions so nearly coincided with mine, that it might seem as if 
a communication of ideas had passed between us ; but, after allowing him 
due credit for his labours, I must still continue to differ from him in a 
number of important points ; yet in order to avoid adding synonymous 
Seneric names, I have revised my original ones, and in all cases, where 
ets character of his genera are conformable to my view, I have adopted 
J names,” :
