Placed by Rev. W. M. Rogers (in litt.) under his var. britannicus, 
‘going off towards var. ferow”’ ; but, after studying the living plant 
twice, I venture to think that it could not be confounded, in that 
state, with either of these varieties, and that iheiefore it merits 
distinction and recognition as a separate variety of R. dumetorum. 
The triangular aspect of the very numerous broad-based thorns, of 
the sepals, of the spaces between the panicle- branches, of the whole 
panicle; and to a less degree of the leaves, their leaflets, and the 
leaf-serration, suggests the pr oposed varietal name as appropriate.
