44 ROSACEJE. 



RUBUS Linn. Bramble, Blackberry. 



It will be understood that the brambles here enumerated have very 

 unequal systematic values. The names adopted are those of Babington's 

 Manual, 8th edition ; corrected in accordance with his Notes in Journal 

 of Botany for 1886. 



The determination of fruticose Ruhi, by ordinary botanists, is so un- 

 reliable that we pass over all notes of such, which have not the sanction 

 of special authorities ; those recorded here have been either named, or 

 confirmed by Prof. Babington.
