to be identical. This Brazilian species has been published by 
Casaretto in his ‘ Decades,’ under the name of 7. Brasiliensis. 
Amongst those of Presl’s species which we have had occasion to 
examine, we have identified many also with well-known older ones, 
and many more still are distinguished on grounds, which in our 
opinion, are insufficient; but on this head there is, we are aware, 
much disagreement amongst systematic botanists; and as several 
of the new species are really valid and well described, it would be 
useless here to enter into details without a careful critical exami- 
nation of the whole, which would take much more time than the 
author can possibly have bestowed on the compilation. In his 
synonyms he has succeeded in detecting some blunders of others ; 
although he not unfrequently corrects one blunder by another. 
If, therefore, this memoir is one which must be consulted on 
account of the right of priority acquired for all really new species 
there described, we would not recommend any of the determina- 
tions of species to be accepted without verification; nor should we 
deem it necessary to adopt Presl’s name where unaccompanied by 
any character or distinctive indications. 
With regard to the date of the work, we see that the 1st of 
April, 1843, is affixed to the preface; although it was only laid 
before the Society on the 21st December, 1843. The date of 
printing is 1844; but it can scarcely have been published in 
that year, as we have heard it was not in booksellers’ catalogues 
till 1846; thus the priority of names over those published in the 
commencement of 1845 might become questionable.
