REMARKS ON THE NOMENCLATURE OF THE EIGHTH 
EDITION OF THE «LONDON CATALOGUK.’ 
By B. Daypon Jackson, Sec. L.S. 
In another article the progress made on the ‘ Index’ of Plant- 
names has been sufficiently given for the present. now must 
explain why I feel called upon to contribute anything to the 
discussion of changes in the eighth edition of the ‘London 
Catalogue of British Pl * Last year, Mr. Frederick Hanbury 
asked look over the MS. of the new edition a ention 
any alterations which recent work on the ‘ Index’ ld suggest 
This I did, and gave him many notes, but informed him that 
I could not give the time necessary to lo u h name i 
t MS.; and that my notes were only upon such items as 
struck me on perusal. Unfortunately I did not see it in proof, so 
that I had no second chance of detecting errors, particularly those 
of the press. 
Shortly after the issue of this edition, Mr. F.C. 8. Roper entered 
Mr. Hanbury handed me Mr. Roper’s queries, where I found many 
which I had already answered in direct c orrespondence, and having 
no wish to go over the same ground an indefinite number of times, 
I desire to place the answers on record here. Some further delay 
would probably have occurred, — not Mr. G. C. Druce sent to the 
Editor an article on the same t apenas I felt bound to take 
the matter in hand without aces for oo * leisure. 
It is by no means easy to answer some the questions pro- 
pounded, as they are often quoted from inteign authors who have 
access to books which are scarce or wanting in this country. I will 
no : 
considerations apply with greater force to 
varieties ; it j is hard en enough at times to run down species, where 
references are fre equently given; but references to varieties are 
often omitted, and thé labour of com paring European floras of, say, 
the last 120 years is more than I ean undertake, svekiaiks as the 
‘Index’ MS. gives no direct citations of varieties as such. 
Putting aside criticisms which are specially addressed to ten 
Editor for the next edition, I will give _ ise which s
