NOTES ON BRITISH RUBI. 917 
determine many critical points. He knew very little apparently of 
the plants of Western Europe as described by Génévi d 
also to make a careful catalogue of all the plants of Europe, not 
simply of the Rubi. We, as well as Focke and Génévier, are able 
more to concentrate our attention upon the Rubi. have, as is 
well known, especially studied our Brambles, as Focke did those of 
Germany, and Genevier those of Western France. I find that 
there is much still to be done before omenclature is quite in 
is our best guide; in the latter Focke. I have endeavoured to do 
this, but feel strongly that the results are often not so satisfactory 
as could be desired. much doubt remains 
are not final, and if I have at a future time to modify my present 
views in many respects. 
Génévier’s book is difficult to use, from his system of arrange- 
ment often distantly separating nearly allied plants, on account 
of the colour of their flora rgans differing. But have 
@ local cause of much difficulty from our having almost uni- 
versally neglected the proportions and colours of the petals, 
Stamens and styles. I believe, with those great authorities, that 
we have neglected a valuable series of characters. as I 
have been able to make use of them I have found them valuable. 
I shall now proceed to make such remarks on the list as it 
Seems to require, omitting all notice of plants which are not likely 
to be misunderstood or questioned. The numbers in at the 
beginning of the remarks on each plant, are those of the ‘ London 
Catalogue,’ ed. 8. if 
1. (416b) R. Inzus L., b. Leesii. I possess R. Leesit as the 
Genévier. Focke says of it that it is the R. obtusifolius Willd., 
but Gandoger (‘ Rubus Nouveaux’) places that next to R. Thuilliert 
P. i i e R. N. The 
Ki. Ideus v. sterilis is apparently a very slight deviation from the

resembles r plicatus, but has ultimately reflexed, not patent

better neglected. That of Boulay, which Focke identifies with our 
R. suberectus, has the strong hooked prickles of our R. plicatus, and
