SUPPLEMENT TO NOTES ON RUBI.—No. 2. 
By Cuartes C. Basineton, M.A., F.R.S. 
I wave recently received, through the kindness of its author, a 
very valuable and interesting paper entitled ‘‘ Some observations on 
“a Genus Rubus. Pt. 1. age og TE Tere of the Rubi in 
he Scandinavian Peninsula,” b W. C. Areschoug, Ph.D.,. Pro-

conclusions. Doubtless the Rubi present almost insuperable di

Yet Genevier made the colour of the petals a prominent part of 
his classification. Focke gives great ind deserved weight to the 
colour of oo flowers, but has avoided what I consider to be the 
erro 
rror of Genevier.
